"gpac",
"gpac"
] | ## Context
We are creating our own Low Latency Hls server using ByteRange mode. We are having problems with some fragments that in
the manifest already has a defined range, but at the moment of requesting them they are still incomplete (they are not
preload hint fragments).
This behavior happens so often that we had to validate the range of bytes requested vs. the current size of the segment
in our server. If the requested bytes are not yet there we need to wait for Gpac to finish writing them.
We are not clear if this behavior is normal.
If the fragments have a byte range defined in the manifest does not mean that they are already ready in that range of
bytes?
(I clarify again that we are not talking about preload hint fragments)
We have been testing with some players and in all of them, we have seen the same behavior.
## Evidence
The player got a playlist like this:

```
The segment_track2_103.m4s is supposed to have its Part 0 or first fragment with a defined range and already written
from 0 to 3996 Bytes.
The player requests that fragment by sending in the headers `Range: Bytes=0-3995`
Our server handles the request and validates the current size of the segment vs. the range of bytes being requested. In
the next image we can see that the segment has a size of `196 bytes` and the fragment that was requested has a range from
`0 to 3995 bytes` i.e. **it is not ready yet**, and we will have to wait until Gpac finishes writing it.
We would like to know why this is happening, the fragment is not ready yet, but in the playlist, it says it is ready...
This is our command:
```gpac -i 'rtmp://nginx/playback' -o http://origin:8080/live/public/playlist.mpd:gpac:dual=1:segdur=2:cdur=0.2:asto=1.8:llhls=br:hlsc=1:cmaf=cmf2:profile=dashif.ll:dmode=dynamic:template=segment:hmode=push:rdirs=gmem```

I'm trying to encrypt and dash an MP4 file (https://www.mediafire.com/file/z92dwuhpwxsdf9c/bbb_avc_aac.mp4/file) using the command `gpac -i bbb_avc_aac.mp4 cecrypt:cfile=crypt.xml -o bbb.mpd:dual:stl:profile=live:pssh=mv` along with the crypt file:

I've got this PSSH from my DRM provider, EZDRM. It has a length of 63 bytes and can be correctly parsed by https://tools.axinom.com/decoders/PsshBox. However, the resulting MPD file has a different value for it:

This value, `AAAAX3Bzc2gAAAAA7e+LqXnWSs6jyCfc1R0h7QAAAD8AAAA/cHNzaAAAAADt74upedZKzqPIJ9zVHSHtAAAAHxIQCOh/QVJCTNSyi9TApITz4RoFZXpkcm1I49yVmwY=`, is 32 bytes longer. Trying to decode it on https://tools.axinom.com/decoders/PsshBox gives an error. Looking at the hexadecimal version I can clearly tell that the start and end of the values are similar, but something is added in the middle.
My main problem is that the DRM provider's servers respond with an `500 Internal server error` when I try to retrieve the license for playback (using e.g. Google Chrome along with `video.js`). I can fix this error by manually replacing the longer PSSH values in the MPD file with the one from the input crypt file. But I'd rather know if I'm doing something wrong while encrypting and dashing my content. Is there a way that I can tell GPAC to copy the PSSH value exactly, instead of rewriting it?
For completeness: I'm running GPAC on macOS with the latest version `2.1-DEV-rev429-g6f4ed0c29-master` installed using `brew install gpac --HEAD`, but I encountered the same problem when trying the older `1.0.1` release. | Widevine PSSH in MPD is 32 bytes longer than provided in crypt file | https://api.github.com/repos/gpac/gpac/issues/2297/comments | 2 | 2022-10-31T18:01:02Z | 2022-11-04T18:32:57Z | https://github.com/gpac/gpac/issues/2297 | 1,430,257,170 | 2,297 |

# Description
A fixed length buffer value_string is allocated in smil_parse_time_list, while in the later memcpy, it doesn't check the length and simply copy content to this buffer, causing overflow.
```c
static void smil_parse_time_list(GF_Node *e, GF_List *values, char *begin_or_end_list)
{
SMIL_Time *value;
char value_string[500];
char *str = begin_or_end_list, *tmp;
u32 len;
/* get rid of leading spaces */
while (*str == ' ') str++;
while (1) {
tmp = strchr(str, ';');
if (tmp) len = (u32) (tmp-str);
else len = (u32) strlen(str);
memcpy(value_string, str, len);
while ((len > 0) && (value_string[len - 1] == ' '))
```
# Impact
Since the content is absolutely controllable by users, an unlimited length will cause stack overflow, corrupting canary, causing DoS or even Remote Code Execution.
# Mitigation
We can just set a length limit to it, making it less than 500 byte.
# Reproduce
On Ubuntu 22.04 lts, make with this.
```
./configure --static-bin
make
```
Run the following command with POC.svg.
```
MP4Box -mp4 -sync 0x1000 ./POC.svg
```
You may get a buffer overflow detected error.

# Description
An arbitrary free can be triggered in csgp_box_del when doing gf_free
```c
void csgp_box_del(GF_Box *a)
{
GF_CompactSampleGroupBox *p = (GF_CompactSampleGroupBox *)a;
if (p->patterns) {
u32 i;
for (i=0; i<p->pattern_count; i++) {
if (p->patterns[i].sample_group_description_indices)
gf_free(p->patterns[i].sample_group_description_indices);
}
gf_free(p->patterns);
}
gf_free(p);
}
```
# Analyse
After encountering a POC (see attachment) can trigger segmentation fault and analysing it thoroughly, I found that this is actully the same bug mentioned in this [issue](https://github.com/gpac/gpac/issues/2214), ASAN detects a huge chunk malloc failed. More precisely, csgp_box_read will return OOM error to gf_isom_box_parse_ex if users try to malloc large chunks. After this, newBox structure is corrupted but the program doesn't fall fast, and later calls gf_isom_box_del(newBox) to free all the elements of it, which causing free to uninitialized memory (ps. no-check flag is not set, if it's set, more unexpected things would happen). By constructing heap fengshui to leave malicious data on heap, this bug can be leveraged to arbitrary free or double free.
# Impact
Since video content is controllable by users, this will crash the service, causing Denial of Service and Remote Code Execution potentially.
# Mitigation
After OOM error, the program should fall as fast as possible. Since the issue mentioned above is closed but unfixed, the best way here is to reset ptr->pattern_count when malloc fails in csgp_box_read. See [pull request](https://github.com/gpac/gpac/pull/2292).
# Reproducer
On Ubuntu 22.04 lts, Make with this.
```
$ ./configure --static-bin && make
```
Run the following command with POC.mp4.
```
$ MP4Box -split 1:2 ./POC.mp4
```
You will get a Segmentation fault. GDB info as below

Hello, I tried to change the value of `speed` [parameter](https://github.com/gpac/gpac/wiki/inspect), but the play back speed does not change. Can you please let me know how to change playback speed when `inspect` filter is used as a sink?
Here is the code I tested, I used the newest code in master.
```
import libgpac as gpac
import time
fs = gpac.FilterSession(0)
f1 = fs.load_src(f"http://localhost/dash/coaster2/coaster2_10x5.mpd")
f2 = fs.load("dashin")
f3 = fs.load("tileagg")
f4 = fs.load("inspect:interleave=true:deep=true:dur=15:buffer=3000:speed=0.02")
f2.set_source(f1)
f3.set_source(f2)
f4.set_source(f3)
btime = time.time()
fs.run()
print(f'\n\nDone, executing time: {time.time() - btime}')
fs.print_graph()
fs.delete()
gpac.close()
```
I changed `speed` to different values, from 0.02 to 100, but the reported executing time is always about 2.4 seconds. If I set `dur` to 15 and `speed` to 1.0, should the total time report be around 15 seconds too?

The [Wiki page for import opts](https://github.com/gpac/gpac/wiki/mp4box-import-opts/) recommends "(see ISO/IEC 23001-8)" under the **colr** option. [That standard has been revised and replaced by three, new, separate standards,](https://www.iso.org/standard/69661.html) because _of course_ ISO would like you to pay for three, separate standards...
Tools like mkvtoolnix, x264, etc. include the codepoints in their documentation.
If directing end-users to the appropriate external document or standard is the desired look in the gpac/mp4box documentation, then perhaps point them to something easily and freely available, preferably directly, like a link to [ITU H.273](https://www.itu.int/rec/T-REC-H.273/en) which I believe the ISO standards are just referencing anyways. | Wiki suggestion | https://api.github.com/repos/gpac/gpac/issues/2288/comments | 1 | 2022-10-17T02:21:42Z | 2022-10-18T14:34:58Z | https://github.com/gpac/gpac/issues/2288 | 1,410,775,812 | 2,288 |

HI， I want to do tile streaming and follow the instruction in https://github.com/gpac/gpac/wiki/HEVC-Tile-based-adaptation-guide
However, after I package the video and ran the following code:
MP4Box -add video_tiled.hvc:split_tiles -new video_tiled.mp4
MP4Box -rem 3 video_tiled.mp4 -out test_tile_lost.mp4
I had some problems opening the output video (video_tiled.mp4 test_tile_lost.mp4). I tried several ways to open but all failed:
1） gpac -i video_tiled.mp4
No filter chain found for PID video_tiled.mp4 in filter fin to any loaded filters - NOT CONNECTED
2）ffplay video_tiled.mp4
No decoder could be found for codec none
Failed to open file 'video_tiled.mp4' or configure filtergraph
3） I open the mp4 file with the some players and it turns out that hvt1 and hvc2 decoder are required.
Besides, I also found some problems with the gpac, like when I ran:
gpac -gui
[Compositor] Failed to load a video output module.
Failed to load filter "compositor:player=gui": I/O Error
I am new to this and I have looked the issues and cannot find the solutions. I think I have the same issue with https://github.com/gpac/gpac/issues/1550#issue-665001400 , but it is closed.
Thanks a lot if you could give some suggestions !

Generated dash files are not synced when the audio track have a `start_time` greater than 0, in this case 975ms.
This is the step that i follow to crypt and dash the file where audio is not synced

--------------------------------
I found a workaround by creating a silence and append it at the beginning of the audio that solve this, but is there another way to solve this with MP4Box ?
Create silence of 975ms
`ffmpeg -f lavfi -i anullsrc=channel_layout=stereo:sample_rate=48000 -t 0.975 975ms.mp4`
Concat the files
`ffmpeg -i 975ms.mp4 -i 1_1635.mp4 -filter_complex "[0:a][1:a]concat=n=2:v=0:a=1" -metadata:s:0 language=fre tmp_1_1635.mp4 -y`

After crypt and dash audio is in sync.

Win10 Firefox cbcs test fails, what is the secret of Firefox cbcs encryption scheme? I also asked the same in dashjs slack but no answers yet. Win10 Edge(playready, cbcs1:9, cbcs0:0)=ok, Win10 Chrome(widevine, cbcs1:9, cbcs0:0)=ok, Android Chrome(widevine, cbcs1:9, cbcs0:0)=ok.
Do gpac talents know more about the Firefox issue?

] | Hi, I just start to use MP4box few days ago. this is fantastic, thank you all.
Could you please check the problem I met below:
Product: gpac/mp4box 2.0 for win-x64 (the latest stable) issued on 2022/02/22
Problem: part of font tag in srt could be miss after importing
Enviroment: Win10 command prompt
Command: mp4box -add vediofile.mp4 -add subtitle.srt targetfile.mp4
SRT sample in input file:
1
00:00:01,200 --> 00:00:04,000
\<font color=#FFFF70>The first language\</font>
The second language (english) line
(File encoding: Win CRLF UTF-8)
Text in MP4 file, same as the exported to STR file:
1
00:00:01,200 --> 00:00:04,000
\<font color=#FFFF70>The first language
The second language (english) line
The \</font> at the end of the first language line is missing.
When I open a new command prompt, and tried to export to a text-only MP4, seems the outfile is correct, but later I repeat the same command, I always got problems.
I tried with an older version (MP4box 0.5), didn't see this problem

Hello,
I follow sample code from this [issue](https://github.com/gpac/gpac/issues/2250), but if `on_rate_adaptation` return -2 for a group, the function `on_rate_adaptation` is not called for that group anymore in subsequent segments.
To demonstrate this point, I inserted a print statement at the beginning of the `on_rate_adaptation` function to print out all groups that were adapted. I returned -2 for the tile in the second row and the second column. The `group_idx` of this tile is 12.
When I run the code, the group 12 is adapted at the first video segment.
But from the second segment onward, the `on_rate_adaptation` was never called for the group 12, meaning this tile was disabled for the whole video.
Here is the [link](https://drive.google.com/file/d/1R3XYIFLFpcKtTn3BgjbNb_IM54W_XKBT/view?usp=sharing) to the mpd file and video tiles.
Here is the code I use to generate the results above:

tool: GPAC-2.1-DEV-rev273-g02437a478-master
The Created tag of my files has been set by the camera where the date had not been set.
I'm attempting to set the tag to the first date/time reported from the GPS using the
```-time [tkID=]DAY/MONTH/YEAR-H:M:S: set movie or track creation time``` format
```mp4box -time 03/05/2022-16:05:40 video.MP4```
but the result from ```mp4box -info video.MP4``` is ```Created: GMT Mon May 2 08:05:40 2022```
Admittedly, the input is local time (GMT+8), which accounts for the time difference, but not the day.
The docs are not clear if there some trickery that adjusts it to GMT. Am I doing it correctly?

Hello,
I am trying to set the buffer of the playback to 2 seconds using this command:
```
gpac httpin:src=http://localhost/dash/coaster2/coaster2_6x3.mpd dashin tileagg ffdec inspect:buffer=2000:dur=5 -graph
```
However, it seems the playback buffer is overwritten by some configuration. The streaming session also hang. Here is the error:
Setting buffer less than 1000 will resume the playback again. Can you please let me know a way to set playback buffer for the inspect filter?.

Using the `src` parameter when joining a multicast feed results in `Feature Not Supported` error. I'm running the latest revision of GPAC on Rocky 8. Without the filtering GPAC receives traffic from 2 sources which isn't working either. When using TSDuck I'm able to join the source specific multicast using
```
tsp -I ip --ssm 10.1.2.3@239.1.2.3:1234
```
Using GPAC I'm trying the following:
```
gpac -i udp://239.1.2.3:port=1234:src=10.1.2.3
```
It results in `Failed to load filter for "udp://239.1.2.3:port=1234:src=10.1.2.3": Feature Not Supported` however. | Source filtering for UDP multicast not working | https://api.github.com/repos/gpac/gpac/issues/2254/comments | 2 | 2022-09-06T13:31:54Z | 2022-11-14T17:10:20Z | https://github.com/gpac/gpac/issues/2254 | 1,363,294,679 | 2,254 |

There is a similar issues[ here](https://github.com/gpac/gpac/issues/2084), but the code provided no longer works, the link provided in the answer also die.
I tried drop the top-left tile by returning -2, then in the later iterations, I want to turn on streaming for the top-left tile by returning 0. However, the streaming client hang without returning errors:
Is there any option to temporarily drop a tile, then later enable streaming for that tile? This drop tile approach is very popular in the research community.
Here is the code of the tile adaptation algorithm:
```
def on_rate_adaptation(self, group, base_group, force_low_complexity, stats):
if group.SRD.x == 0 and group.SRD.y == 0:
print(f'We are adapting on globalid: {global_id}, group_idx:{group.idx}, active quality: {stats.active_quality_idx}')
if stats.active_quality_idx != -2:
return -2
else:
return 0
return 0
```

I'm trying to add cover to mp4 files, so I am using the code in cmd as it fallows:
`mp4box -add cover=myfile.jpg "my_video.mp4"`
And I get this error:
> Failure while importing media: Requested URL is not valid or cannot be found
> Error importing cover=myfile.jpg: Requested URL is not valid or cannot be found
This jpg files is 409*545 px
Like a week ago, I did add cover to some video files with a older version of gpc, and it worked.
Today, I'm getting this issue, so I installed latest gpac version, but same "Requested URL is not valid or cannot be found" error.
I will appreciate if someone help me out.

] | We are working with MOV files produced by Atomos Ninja V devices, which create a broken MOV file structure. The company is not responding to service such low level mistakes they made, but that is completely another topic.
**The issue:**
Audio is in "in24" format, as 24-bit 4-channel 48000 samples/second track (length 1.2sec in sample below). The path:
```
moov.trak[1].mdia.minf.stbl.stsz { 20-8 @ 65779208 = 12 }
. . . . . - version = 00
. . . . . - flags[3] = {00:00:00}
. . . . . - sample_size = 00000003 = 3
. . . . . - number_of_entries = 0000E100 = 57600
```
Given the 24-bit 4-channel configuration, one would expect a figure of 12 written in the constant sample size field. But they are made it wrong. Comparing it with other random internet found files, we see proper calculation of sample size, as a number that covers all bits of all channels = one audio sample in the time axis.
The consequence is dramatic - GPAC (and even my own mov reader code) would access only the first quarter of every given chunk, since we naturally use the sample_size * samples_in_chunk (of stsc). It does not return correct data when reading in our app using gpac library, and it does not return the correct -raw track dump using the MP4Box tool.
While we were debugging this odd behavior, I found that e.g. ffmpeg includes a quirk that overrides the constant sample_size with a calculated value that originates from the sample description (stsd) atom - if the audio is uncompressed, its easy to calculate the sample size. And this value is used then instead of the value that is read from the file - likely taking the path of - they got the data right, but they got some key metadata wrong.
**Potential solution**:
Could GPAC implement such override, eg. in the following way:
- for simple lpcm/in24 format, decode the stsd and derive an expected sample_size
- if the file indicated sample size is smaller, override it with the calculated size
- emit a big warning, that the user deals with potentially broken file (ill formatted)
- the functionality could be optional/masked, if there is a way to do it easily
**Alternative way:**
Is it possible to override the loaded isoMedia with a custom sample_size or stsz atom, when we are only using gf_isom_get_sample to read such file? We can easily detect this type of a badly setup MOV file.

I tried to use FLAC via HLS and was running into some issues. Trying to DASH a .flac file directly flat out doesn't work right, GPAC creates multiple periods from the single input.
At first it seemed like making a .mp4 file out of the .flac first would work, but then I ran into stuttering / skipping (depending on the player used) no matter which fragment or segment settings I used, even without a video stream to muddy up the fragment / segment lengths. Then I noticed the glitches always occurred at the same exact timestamps, and even with single file / single fragment output.
I went back and checked the "original" remuxed FLAC .mp4 used as the input for DASH, and lo and behold, it has stuttering, and you can see it in the decoder output when you try to play it back with GPAC player:

```
Every `[flac]` or `[FFDec]` message in the console corresponds to an audible glitch. I tried `-flat` to see if it might be an interleaving issue, but it didn't make a difference. Something about the way GPAC is muxing the file is causing the FLAC decoder (both here in GPAC and elsewhere) to detect channel mode and bps switches that don't exist in the source .flac file at all.
For comparison, even though ffmpeg complains that FLAC in mp4 is experimental, it seems to work just fine.

ffmpeg's file plays through to the end without a single glitch or console message, nor does it cause issues when sent through GPAC dasher.
Using ffmpeg to remux either mp4 back to .flac produces a file with an identical Audio MD5 to the original. | FLAC files not being muxed properly | https://api.github.com/repos/gpac/gpac/issues/2244/comments | 4 | 2022-08-22T22:44:15Z | 2022-09-16T10:47:39Z | https://github.com/gpac/gpac/issues/2244 | 1,347,081,081 | 2,244 |

Hello. I have a problem about muxing WEBVTT subtitle to mp4box. On muxed mp4 video using mp4box with WEBVTT won't show the subtitle only in mpv or VLC.
In mkvtoolnix muxed mkv with webvtt, it shows correct subtitle.
See the two screenshots and shared files below:

Notice that the "Sample" number is different in each representation because the xHE-AAC encoder uses different frame sizes for different bitrates. Nevertheless, the CTS for each RAP is the same in both files.

] | Hello,
My goal is to be able to build GPAC on my own for an Android version that I have available following the guide on the wiki https://github.com/gpac/gpac/wiki/GPAC-Build-Guide-for-Android. However, I'm facing problems running the gpac version built on my own. So I took a step back to have at least one version running correctly before do my changes.
Therefore, I am trying to run GPAC on Android using the nightly version `gpac-2.1-DEV-latest-master`. I have already tried on a phone with Android API 31 and an Android API 28 via Android Studio Emulator. On both cases the app just crashes while trying to use the "_Open URL_" function.
The URL that I'm trying to open contains a HEVC DASH-SRD manifest and can be found [here](https://www.mediafire.com/file/l4rydewrvwlubrt/new_york_tile_lost.mpd/file.)
I've also tried with an URL with a MP4 video and the same thing happened.
Using the Logcat tool from Android Studio it can be seen a few informations of what is happening

Can someone help me with this? It seems to be a problem with the libraries, but I am not really sure what it can be done.
Maybe I am not using the app correctly. I've also tried to run the URL Manifest in the "_Run gpac_" function running the command as I would on the PC, but it is not recognizing the `vout` filter as follows:
`-i http://xxxxxxxx/hevc_tiles_mp4/new_york_tile_lost.mpd vout`
The gpac that I've compiled have other problems that it is worth to have its own issue related to it. However, having a stable gpac android version is my highest priority.
I really appreciate any help on this case!

This is some feature suggest concerning output message from MP4Box
Error output saved to a mariadb column of type text reveal ANSI, an example error:
```
[33m[Importer] Cannot load filter for input file "/dash/3_644495.vtt:lang:fre"

```
Progress statistiques parsing the output of the following command to show progress:
```
/usr/bin/MP4Box -dash 4000 -frag 4000 -rap -fps 24 ...
```
which produce
```

```
is not possible.
The following is perfect:
```
/usr/bin/MP4Box -crypt drm.xml in.mp4 -out out.mp4
```
Output this clean one line updated
```
Encrypting: 100.00 %
```
To summarize, an option to show only errors and stats to command line would be very nice.
ffmpeg have options to do exactly that
```
ffmpeg ... -v error -stats
```
Hope this make sense

I have local videos which are considered different qualities for the same video, and I want to package them in HLS and Dash.
I was able to successfully generate both of them but without any URL to host from.
I read your wiki and tried to do so, but I encountered issues and the m3u8 did not have the host URL
I saw
[DASH Low Latency](https://github.com/gpac/gpac/wiki/dash_low_latency)
[HLS Low Latency](https://github.com/gpac/gpac/wiki/llhls)
I suspect that the commands used in for example (DASH Low Latency) are for live video encoding | [Question] How to insert my website url to M3U8 and MPD files ? | https://api.github.com/repos/gpac/gpac/issues/2235/comments | 9 | 2022-07-27T12:34:26Z | 2022-07-29T11:31:10Z | https://github.com/gpac/gpac/issues/2235 | 1,319,499,398 | 2,235 |

```Dockerfile
FROM fedora:29
RUN dnf group install -y "C Development Tools and Libraries" "Development Tools"
RUN dnf install -y zlib-devel
RUN mkdir -p /var/repo
WORKDIR /var/repo
RUN git clone https://github.com/gpac/gpac.git -b v2.0.0
WORKDIR /var/repo/gpac
RUN ./configure --static-bin
RUN make
```
Basically I cannot get past this error.
```

```
I am **guessing** that it is trying to static link with some `glibc` libraries which is generally discouraged (for good reasons). You probably want to be linking dynamically to all of `glibc`, then statically to everything else. I wrestled with your build scripts for a couple hours and I couldn't figure it out.
Extra info:
* The fedora build succeeds when I remove `--static-bin`
* I tried 2 other branches of gpac:
* `master` also has the error
* `v1.0.1` does not have the error

] | Hey folks, Im using the latest nightly build (2.1-DEV-rev254-g0102c5d4-master) where I try to convert a HLS m3u8 adaptive stream manifest to a DASH mpd manifest using the following command:
`MP4Box -mpd master.m3u8 -out master.mpd`
The problem here seems that MP4Box does not seem to respect that all representations stored are in a seperated folders, This is the mpd I get back from my command:

I can clearly see that there is a refrence to a folder, where is that folder reference translated at the mpd output? To me it seems they are simply getting ignored, it's not there. Result is that VideoJS is not able to play the stream at all where the m3u8/HLS stream works fine.
Any way to correct this?
Besides I see that mimeType is always "video/mp2t" where my stream is fragmented mp4.

"gpac",
"gpac"
] | Hello folks,
I have the following HLS structure given:
Within each folder, I have such a structure:
As you can maybe already imagine, I only have HLS in use. Now I also wanted to have Dash compatibility, so I started to convert the master.m3u8 on each subfolder like so:
`MP4Box -mpd master.m3u8 -out master.mpd`
Awesome, now I have a mpd file that basically references the m3u8 playlist. But why referencing, why not simply generate an independent mpd file from the m3u8 that references the m4s/ts segments directly?
This is the m3u8 I use as input:
```
#EXTM3U
#EXT-X-VERSION:7
#EXT-X-TARGETDURATION:9
#EXT-X-MEDIA-SEQUENCE:0
#EXT-X-MAP:URI="init-a-aac-de-mp4a.40.2_128000.m4s"
#EXTINF:9.002667,
f-0000.m4s
#EXTINF:1.056000,
f-0001.m4s
#EXT-X-ENDLIST
```
This is what I get in return:
```
<MPD type="static" xmlns="urn:mpeg:dash:schema:mpd:2011" xmlns:hls="urn:gpac:hls:aes:mpd:2015" profiles="urn:mpeg:dash:profile:full:2011" id="master.m3u8" mediaPresentationDuration="PT9S" minBufferTime="PT1.5S">

```
I'm not sure how compatible such an output is, can somebody give an advice here?
This was the first "issue", if it's really an issue in the end...
The second problem I have is at the master.m3u8 file at the root directory of my HLS structure.
The file looks like this:

If I run the MP4box command from above against this m3u8 file I get back the following error:
```
MP4Box -mpd master.m3u8 -out master.mpd
MP4Box: media_tools/m3u8.c:752: declare_sub_playlist: Assertion `0' failed.
Aborted
```
Can somebody help? How can I convert my HLS to a Dash structure?

Hello!
I'm trying to put DRM (fairplay) with `HLS SAES` but for some reason is not working as expected
1. When I put the `constant_IV` it puts it in each fragment when it should only put it in the "header" and besides it is not constant in each video fragment it increases in 1. **(look IV in the actual m3u8)**
2. The encryption type of the `EXT-X-KEY:METHOD` is left as `AES-128` and I am expecting it to be `SAMPLE-AES`.
### Command
```bash
gpac -i 1080.mp4 -o res-hls/manifest.m3u8:segdur=10:hlsdrm=drm-hls.xml
```

I don't know if maybe I'm missing something, but from all the documentation I've read, the command and the DRM config looks good

**Issue**
When downloading a nightly build of GPAC from this link https://gpac.wp.imt.fr/downloads/gpac-nightly-builds/ it states on that very site that the versions for OS X (or macOS how they call it now) are compatible "with 10.7 and above". This no longer seems to be a case.
Downloading the latest version and installing it on Mac OS X 10.10.5 (Yosemite) results in an application bundle that's blocked out in Finder (with a stop symbol across the icon) and running the contained binaries directly from Terminal results in following issue:
```
$ /Applications/GPAC.app/Contents/MacOS/gpac --help
dyld: Library not loaded: /System/Library/Frameworks/CoreImage.framework/Versions/A/CoreImage
Referenced from: /Applications/GPAC.app/Contents/MacOS/./lib/libavdevice.58.dylib
Reason: image not found
Trace/BPT trap: 5
```
With how badly the OS X ecosystem works regarding backwards compatibility you're probably no longer be able to fix the package for older systems (albeit this would be appreciated), so an update of the information of the website seems to be reasonable as a fix. | Website: Nightly Builds are not "compatible with OS X version 10.7" (and some above) anymore | https://api.github.com/repos/gpac/gpac/issues/2229/comments | 6 | 2022-07-19T14:34:30Z | 2022-09-29T17:25:42Z | https://github.com/gpac/gpac/issues/2229 | 1,309,617,356 | 2,229 |

I don't understand what first_IV is for and if i should edit this value ?

**Impact**
can cause a program to crash, use unexpected values, or execute code.
Occurrences:
avc_ext.c:2490
ps: this test was still based on the newest mp4box+asan. The bug happened in avc_ext.c:2490 which was the same location with the other issue i submitted (https://github.com/gpac/gpac/issues/2218). Maybe asan mistakenly reports "heap-use-after-free" instead of "heap-buffer-overflow". Pls check it again.

Dolby vision profile 5 is working great on Apple TV but Dolby Atmos is recognized as DD+ only. If I use mp4muxer Dolby Atmos works. This can be reproduced demuxing any mkv with FFMPEG and muxing it with mp4box.

Hello:
I have one video without subtitle, its name: 13864_en.mp4; I have one English subtitle in SRT format: 13864_en.srt; I have yet another Chinese subtitle in SRT format: 13864_cn.srt.
I can make a video with English subtitle with the following simple command:
mp4box -add 13864_en.srt:hdlr=sbtl:lang=eng 13864_en.mp4 -out 13864_English.mp4
But when I tried to make a video with Chinese subtitle, none of my commands works.
The following is the log:
D:\Videos\Youtube>mp4box -for-test -add 13864_en.mp4#video -add '13864_cn.srt:lang=zh-Hans:name=Mandarin (Simplified)' -out 13864Chinese.mp4

ps:
it also crashed under the newest gpac version(MP4Box - GPAC version 2.1-DEV-revUNKNOWN-master),,so the bug was in the version prior to GPAC version 2.1-DEV-revUNKNOWN-master.

] | I need to overlay an image that has an auxiliary alpha mask over another image. HEIF specification allows me to do this, as is showcased [in the "Alpha Mask" example](https://nokiatech.github.io/heif/examples.html#alpha-1). I tried to reconstruct this sample HEIF image. The original file `alpha_1440x960.heic` can be found [here](https://github.com/nokiatech/heif/blob/gh-pages/content/overlay_grid_alpha/alpha_1440x960.heic).
Running `mp4box -info alpha_1440x960.heic`:
```
# File Meta type: "pict" - 5 resource item(s)
Primary Item - ID 1009

Item #4: ID 1009 type iovl Name "Derived image" size 1440x960
File has no movie (moov) - static data container
```
Extract the raw streams from the original `alpha_1440x960.heic`:
```
$ mp4box -dump-item 1002:path=1002.hvc alpha_1440x960.heic
$ mp4box -dump-item 1005:path=1005.hvc alpha_1440x960.heic
$ mp4box -dump-item 1008:path=1008.hvc alpha_1440x960.heic
```
Reconstruct the HEIF image:
```
$ mp4box \
-add-image \
"1002.hvc":id=1002 \
-add-image \
"1005.hvc":id=1005 \

The derived image, `ID=1009`, does not render properly on my Mac. Instead of correctly rendering an overlayed alpha image, it just shows all black. The original image, however, renders correctly.
By the way, running `mp4box -info reconstruct.heic` shows
```

"gpac",
"gpac"
] | Issue:
Calling `mp4box -splits` doesn't distribute chapter marks onto the split files.
Example:
10min mp4 video with a chapter that starts at 9 minutes. After splitting, the first part contains the chapter mark even though that mark points to a section that is in another split file.
Command used:
`mp4box v.mp4 -splits 1024 -out v_$num%03d$.mp4`
Explanation:
While trying to split mp4 files by size (-splits option) I noticed, that chapter information is simply copied to ~~the first split while all other splits don't contain any chapter information at all~~ all splits without rebasing. This results in broken chapters, since chapters may point to times after the first split file.
Expected behaviour:
Chapter marks are distributed to the according split files (and rebased since every split video starts at 0 time again).

What I would like to do is convert an mpegts file that contains a single video stream and a single KLV data stream to CMAF according to [MISB ST1910](https://nsgreg.nga.mil/doc/view?i=5097). What I'm most interested in is mapping the KLV metadata packets into EMSG boxes in the output CMAF. There is a demo [DASH manifest](https://www.mistandards.org/demo/cmaf/data/ST1910.1/H264/cmafsample.mpd) that looks like it was created with GPAC that gives me some hope, but I'm not really sure where to start. | Producing MISB ST1910 CMAF from MPEGTS | https://api.github.com/repos/gpac/gpac/issues/2204/comments | 7 | 2022-06-08T20:47:14Z | 2023-06-15T22:37:10Z | https://github.com/gpac/gpac/issues/2204 | 1,265,290,335 | 2,204 |

Hello,
Previously it was possible to use the symbol " * " as a wildcard to dump all raw and srt files embedded in a mp4, see https://github.com/gpac/gpac/issues/925
Example :
`MP4Box.exe -dump-cover -dump-chap-ogg -raw * -srt * File.mp4`
I have not tested this since a while but seems that this doesn't work anymore, it returns an error message in both powershell and cmd :
removing the "-raw*" and "-srt*" removes the error message.
Thanks a lot.

"gpac",

] | I hope that makes sense. Unless I am missing something, there appears to be no way to generate an HLS M3U8 with absolute paths. It definitely shouldn't be a default option (Apple recommends relative paths but allows for both), yet having a way to enable it for edge cases that require it would be nice.
```mp4box -dash 10000 file.mp4 -segment-name "$File$_dash$FS$$Number%02d$" -frag-rap -base-url "https://some.url/some/folder/" -mpd-info-url "https://files.catbox.moe/om3tcw.webm" -mpd-title "Mikoboat (2020)" -mem-frags -out Mikoboat.mpd:dual```
The output .mpd does have the base-URL as expected. The m3u8 always just has segment names.
```
#EXTM3U
#EXT-X-TARGETDURATION:10
#EXT-X-VERSION:6
#EXT-X-MEDIA-SEQUENCE:1
#EXT-X-INDEPENDENT-SEGMENTS
#EXT-X-MAP:URI="file_dashinit.mp4"

file_dash01.m4s
#EXTINF:10.00,
file_dash02.m4s
#EXTINF:10.00,
file_dash03.m4s
```
Whereas it would be nice to output m3u8 directly (without batch Find/Replace-ing in a text editor) that looked like:
```
#EXTM3U
#EXT-X-TARGETDURATION:10
#EXT-X-VERSION:6
#EXT-X-MEDIA-SEQUENCE:1

https://some.url/some/folder/file_dash02.m4s
#EXTINF:10.00,
https://some.url/some/folder/file_dash03.m4s
```
I tried adding `-base-url` again after the `-out` filename, but that changed nothing. It looks like there's already an option for doing the reverse: forcing URLs to be included when generating an MPD from HLS?
> **-url-template-sim**: use SegmentTemplate simulation while converting HLS to MPD

Actually i'm editing MPD file after creation to add file.vtt to load it with dash.js:
```
<AdaptationSet id="3" contentType="text" mimeType="text/vtt" lang="fre" startWithSAP="1">
<Label>Français forcés</Label>
<Role schemeIdUri="urn:mpeg:dash:role:2011" value="forced-subtitle"/>
<Representation id="3" bandwidth="256">
<BaseURL>3_fre.vtt</BaseURL>
</Representation>
</AdaptationSet>
```
I was hopping MP4Box can do it from command line, for example:
```
MP4Box -dash 4000 -frag 4000 -rap -fps 24 \
test.mp4#trackID=1:id=video \
test.mp4#trackID=2:id=fre \
/path/to/3_fre.vtt#subtitle:id=3:asID=3:role=forced-subtitle:desc_as='<Label>Français forcés</Label>' \
-out index.mpd
```
Thank you.

From my understanding :asID=VALUE add an ID to the AdaptationSet parent of the Representation.
Using this command line:
```
MP4Box -dash 10000 -profile dashavc264:onDemand test.mp4#trackID=1:id=video test.mp4#trackID=2:id=fre test.mp4#trackID=3:id=eng test.mp4#trackID=6:id=fr_forced:asID=fr_forced:role=forced-subtitle test.mp4#trackID=7:id=fr_full:asID=fr_full:role=subtitle -out index.mpd
```
I was expecting this result (truncated):
```
<AdaptationSet id="fr_forced" segmentAlignment="true" lang="fra" startWithSAP="1" subsegmentAlignment="true" subsegmentStartsWithSAP="1">
<Role schemeIdUri="urn:mpeg:dash:role:2011" value="forced-subtitle"/>

] | Hi,
I'm trying to use DASH segmentation to remux a TS video into a DASH.
But I can't get sepparated streams (video/audio).
When I use one of the input modifiers (#audio, #video or #trackID), for example:
MP4Box -dash 1000 -profile live -segment-name file_ input.ts#audio -out output.mpd
those modifiers are ignored, and the output alerts with the message:
**Arg tkid set but not used**
Always i get all the streams muxed in the same segment.m4s
It works ok if my input is encapsulated in a mp4.
I've tried with the version
GPAC version 1.1.0
and the last
GPAC version 2.0-revrelease
with same result.
It's possible to use the modifiers when opening a TS file?
Thank you very much

] | Hi,
I would like to know if it's doable to force the sampling rate during audio stream import within MP4Box...because I would like to mux h264 video and opus audio streams but sometimes my audio streams have sampling rate @ 44.100 KHz.
Import opus streams to mp4 forces the sampling rate @ 48000 Hz. So, my question is : is it possible to put the sampling rate @ 44.100 KHz for such streams within MP4Box ?
Thanks in advance.

] | Hello,
I have used Kvazaar to split a 360-degree video (YUV format) into 3x3 tiles and make a .hvc file. I then used the .hvc file to package within a container via MP4Box `$ MP4Box -add video_tiled.hvc:split_tiles -fps 30 -new video_tiled.mp4`
Later I used the generated file to create an MPD file using the following command `$ MP4Box -dash 1000 -rap -frag-rap -profile live -out dash_tiled.mpd video_tiled.mp4`
Although the manifest file is playing on Osmo4, the tiles have been split and I can observe the splitting in the video, but it seems to be still in YUV format. Also, I am not able to play the video on my Exoplayer application. The lines in the manifest file seem to be okay. (Attaching it here for reference). Can someone point out what am I missing?

Hello,
I am working with a task of be able to view clips of video that happened during the day, triggered by motion detection from a camera. And be able to stream these video in a single player, for example shaka player.
I've thought of creating a virtual 24 hours video of, for example, 10 clips of different duration, and make a viable manifest file which kan display this video and information on a 24 hour timeline?
Or is it some other way I can create a manifest which will use all of these small videos?
