] | Hello, everyone. Is there any method to obtain the frame data of the hevc tiled video?
When i use MP4Box to produce DASH video from a single MP4 file, I can simply concatenate the init.mp4 and the .m4s files like this:
```
cat init.mp4 1.m4s 2.m4s 3.m4s > target.mp4
```
Then i can use other tools to obtain the frame data of the video.
However, if i produce a tiled DASH video according to the wiki "HEVC Tile based adaptation guide", i find that the method i used no longer works.
When i want to concatenate the DASH files of one of the tracks (3x3+1 in wiki), the output can not be played seperately which means i can not obtain the frame data with other video processing tools(like ffmpeg).
Is there any helpful method in GPAC that can achieve this? | How to obtain the frame data? | https://api.github.com/repos/gpac/gpac/issues/1751/comments | 3 | 2021-04-21T07:12:36Z | 2021-04-21T08:53:45Z | https://github.com/gpac/gpac/issues/1751 | 863,524,074 | 1,751 |

] | The AV1 parser doesn't read enough bytes for the ispe element - getting the correct values requires looping over every OBU_FRAME or OBU_FRAME_HEADER in the source bitstream and finding the maximum size, but currently it only reads one block (currently 5000 bytes). There are a couple of solutions for this, but I'd like to know which one is appropriate for gpac.
1. Configure the AV1 parser to read an arbitrary number of bytes.
2. Use a function like av1_get_layer_size added by my a1lx PR specifically for the ispe element to determine sizes (it could in fact be the exact same function).

Hi,
After reading the
documentation, I've tried to use ffavin to load a stream through [NDI](https://www.ndi.tv/sdk/).
[EDIT]
To reproduce :
ffmpeg compilation:
```sh
sudo cp -av /NDI_Folder_Location_for_linux/lib/x86_64-linux-gnu/libndi.so* /usr/lib/
#compile ffmpeg
#configure
wget -O ffmpeg-snapshot.tar.bz2 https://ffmpeg.org/releases/ffmpeg-4.1.3.tar.bz2 && tar xjf ffmpeg-snapshot.tar.bz2 && sudo rm ffmpeg-snapshot.tar.bz2
cd ffmpeg-4.1.3
./configure \
--extra-cflags="-I/NDI_Folder_Location_for_linux/include" \
--extra-ldflags="-L/usr/lib/" \
--extra-libs="-lpthread -lm" \
--pkg-config=pkg-config \
--enable-libndi_newtek
#make
make -j$(nproc)
sudo make install
#quick test log
ffmpeg -h demuxer=libndi_newtek
```
Gpac compilation:
```sh
make config.mak
make -j$(nproc)
```
I've compiled ffmpeg with NDI support - 4.1.3 -, and gpac with my local version of ffmpeg: when running :
`./gpac -hx ffavin:libndi_newtek`
i get :
``` sh
ffavin:libndi_newtek
Description: Network Device Interface (NDI) input using NewTek library
Version: Lavd58.5.100
Max Input PIDs: 1
Flags: URLMimeProber
Priority 0
Options (expert):
find_sources (bool, default: false): Find available sources
wait_sources (uint): Time to wait until the number of online sources have changed
allow_video_fields (bool, default: true): When this flag is FALSE, all video that you receive will be progressive
extra_ips (str): List of comma separated ip addresses to scan for remote sources
```
all good so far.
But when trying to specify my input I don't get the right command..
<br>
With ffmpeg i do:
```sh
ffmpeg -f libndi_newtek -i "PIERRE-ALL-SERIES (NDI_TEST)" -frames:v 100 output.mp4
```
<br>
I have assumed this would work:
```sh
./gpac -i libndi_newtek:i="PIERRE-ALL-SERIES (NDI_TEST)" compositor vout
```
but i get : `Failed to load filter for "libndi_newtek:i=PIERRE-ALL-SERIES (NDI_TEST)": Requested URL is not valid or cannot be found`
Any pointers?
Thanks for your great work and support, :).

] | I'd like to generate a HLS .m3u8 at the same time as the DASH .mpd, but - as I'm new to streaming tech - have been overwhelmed by all the options available.
Having read about the gpac 0.9.0 rearchitecture I gather this is possible, and have been exploring 1.0.1 on Debian testing - but can't see how to manage it.
I've successfully used FFMPEG to create multiple scaled represenatations of a video (and a single separate audio file), and then MP4Box to create an .mpd file and adjust the video container information as needed - resulting in a working stream with single files for each representation (serving byte-ranges via Apache).
I'm currently using gpac 0.5.2 on Debian 10 this with command:
```MP4Box -dash 5000 -frag 5000 -rap -profile onDemand -out film.mpd film_360.mp4 film_540.mp4 film_720.mp4 film_1080.mp4 film_audio.mp4```
It seems that, to get the .m3u8, I need to specify the *dasher* filter with the *dual* option, but haven't wrapped my head around how to do this.
Any suggestions or examples?

I'm working on 360 videos using MPEG-DASH-SRD.
Details about my work are discussed in issue #1683.
I'm trying to compute VMAF and PSNR for 360 videos. For which I used avfilter with libvmaf.
When I calculated vmaf I got 0 vmaf score for most of the frames.I have attached the log for the same.
I'm not sure if there's some issue with my video or I'm calculating vmaf in wrong way.
I used following command.
`gpac -i original.mp4:#ffid=dist -i distorted.mp4:#ffid=ref ffavf::f=[dist][ref]libvmaf=log_path=libvmaf.log @ -o null`
vmaf score

This second video (distorted.mp4) can be played with only mp4client,if there's a way to make it compatible with every other video player please let me know.
Also I wanted to calculate psnr and ssim score along with the vmaf for which I used following command but I just got the vmaf score.
`gpac -i original.mp4:#ffid=dist -i distorted.mp4:#ffid=ref ffavf::f=[dist][ref]libvmaf=log_path=libvmaf.log::psnr=true=log_path=psnr.log @ -o null`

] | I am trying to create 100% even duration of video(h264) and audio(aac) segments. This is a known challenge with AAC codec 1024 sample length. We have this an even magic integer `seconds=8, rate=48000, dashscale=48000, segdur=384000` to be used. Video segment's duration is easy to match an integer duration.
**MP4box always writes one extra MDAT.TRAF payload element <ins>to the last audio segment</ins>**, it does not matter how many seconds I encode from the input.mp4 file. A bug in a segment splitter's audio sample loop counter?
I am trying to write 100% exact 1..n segments, encoding input timelimit is matched to a multiplier of 8 seconds.
Input file:
[00_llama_1080p_25fps.mp4](https://m.dtv.fi/dash/00_llama_1080p_25fps.mp4)
Statistics of the segments and few arguments, **Please note must use** ` -movflags empty_moov` flag so MP4Box is able to write an even duration of audio segments, removing a flag will make mp4box more easily write uneven audio segments, even the first segment may not match our 8s target.
```
ffmpeg : -t XX encode XX seconds from the input file
negative_cts_offsets enable negative MOOF/TRAF/TRUN.cts timestamp
empty_moov write initial moov(mp4box writes an even audio durations)

One more thing I want to add: Migrate the Android/iOS integration to Gradle/PODs. It is very **hard** to get a successful .so files and create wrappers. FFMPEG has one project with gradle integration for Android and iOS, You should do the same.

- I can remove SEI messages in a H264 bitstream upon extracting it:
`gpac -i input.mp4#video rfnalu:nosei @ -o raw.264`
- I can also remove SEI messages upon importing a raw stream directly:
`mp4box -add raw.264:nosei -new output.mp4`
- I can't remove SEI messages upon importing a stream from an existing .mp4 container, with mp4box (I get no errors but `nosei` option is ignored):
```
mp4box -add input.mp4:nosei -new output.mp4
mp4box -add input.mp4#video:nosei -new output.mp4
```
- I can't remove SEI units in-place by using the "self" mode with mp4box (`nosei `option is not marked with an "S" in the [documentation](https://github.com/gpac/gpac/wiki/mp4box-import-opts), which if I understand correctly means it cannot be used in this mode, but as a side note I can't use "self" mode with any option at all, even with the example in the docs, I always get `[Importer] Cannot load filter for input file "self"`)
`mp4box -add self:nosei src.mp4`
- I can however remove the SEI upon importing a stream from an existing .mp4 container with gpac:
`gpac -i input.mp4#video rfnalu:nosei @ -o output.mp4`
How can I remove SEI messages in-place (if even possible)?
In the last command how can I apply the rfnalu filter to a video stream but also passthrough/stream-copy all other tracks to the output file? The above only adds the video stream to output.mp4.

Since most contents don't contain this information, this is a regression for most users. I propose we recompute a bitrate when missing. @jeanlf proposes to add this in the isobmff demuxer.
The bitrate cannot be reliably estimated until a sufficient amount of data is available.

(I need separate audio and video for some other reasons)
2) Package to DASH:
`MP4Box -dash 1920 -frag 1920 -rap -bs-switching no intermediate-video.mp4#trackID=1 intermediate-video-1.mp4#trackID=2 intermediate-video-2.mp4#trackID=3 intermediate-audio.mp4#trackID=1 -single-file -single-segment -out output/manifest.mpd`
you see there - intermediate-video-1.mp4, intermediate-video-2.mp4 - they should be either symlinks or copies of intermediate-video.mp4 - otherwise it just doesn't work and the result contains only 1 rendition. I just cannot use the same file! It was not a problem with symlinks, but now we moved to the NFS storage and they are not an option anymore. Copying the file is too slow.
Is there a way to use one source mp4 file to get multiple renditions in the manifest?

Hello everybody,
I tried to change the language and name of audio tracks using mp4box (–lang 2=Eng -name 2="Surround 5.1").
The tool does indeed set the language but the track name stays the same (title0). Did I do something wrong, is it the tools fault or is it simply not possible to change names in mp4box.

We created a new Android Studio 4.1 project compatible with the newest Android tools, by following the **mp4box_android** sample project.
The new Android project can be downloaded from [here](https://drive.google.com/file/d/1R0iV5oK9KSArBYV0CsFCU1CYwXQ9RBrp/view?usp=sharing).
We granted the **write_external_storage** runtime permission and set `android:requestLegacyExternalStorage="true"` in the AndroidManifest.xml since we are using `compileSdkVersion 30`
We added the sample video onto device file within the Android Download folder [legend.mp4](https://drive.google.com/file/d/122-BJc9lJOHssyM_hLFHObi8XrZlHgoT/view?usp=sharing)
Within the Android app we have tried to load successfully all the .so libs compiled
Within the Android project we have tried to execute the following command for mp4box: "`MP4Box -frag 240000 /storage/emulated/0/Download/legend.mp4 -out /storage/emulated/0/Download/legend_frag.mp4`"
We get the following console output:
```

**Current** result:
- no output video file
**Expected** result:
- /storage/emulated/0/Download/legend_frag.mp4 should be created
We have tried different command lines but with no good result.
One thing I have to note here, when doing -frag or some other command lines, the terminal should pop the message `WRAPPER_JNI: mp4terminal::end` only after ~10seconds since the video processing takes a while, depending of how long the input video is. Currently `mp4terminal::end` comes right after `mp4terminal::start` no matter which command line is executed

] | Hi,
I'm trying to use mp4box to generate growing and timeshiftable dash output that can be played in browser (currently trying shaka/video.js).
Application generating mp4 source is ffmpeg with empty_moov+omit_tfhd_offset+frag_keyframe+default_base_moof movflags set (25 frame GOP) and tried various other settings.
Currently using node-gpac-dash to serve the dash content and a small node.js based webserver for the video.js/shaka test page.
The result is playing back ok in chrome but mp4box doesn't seem to be handling the growing mp4 file, so the browser is never able to play beyond the duration of the clip at the time mp4box was run, I've seen suggestions to loop mp4box in shell script or similar eg. issue https://github.com/gpac/gpac/issues/835 but am not clear how to prevent it re-dashing media that was previously dashed or if there's a way to do this natively in mp4box or mp4box.js?
This is the mp4box command (and output below): ./MP4Box -dash-live 1000 -frag 1000 -profile live -mpd-refresh 1000 -time-shift 7200 -out /opt/node-gpac-dash/dash.mpd /tmp/source.mp4

Slept for 0 ms before generation, dash cumulated time 1966
etc. (it sleeps forever after this).
In an ideal world I think it would be cleaner not to have to write dash media to the disk (to avoid having to housekeep etc) so wonder if I could use mp4box.js to avoid this step by passing boxes directly to browser over websockets but I think it may have a similar issue and in any case feels like we need to resolve the growing mp4 issue first.
Any Help Appreciated!

I have an .mp4 container with 1 video stream and 3 audio streams (info is taken via MediaInfo):
```
Video, StreamOrder:0, ID:1
Audio (eng), StreamOrder:1, ID:2
Audio (ita), StreamOrder:2, ID:3
Audio (fre), StreamOrder:3, ID:4
```
This is what happens when I add a subtitle via ffmpeg:
`ffmpeg -i in.mp4 -i subtitles.srt -map 0 -map 1 -c copy -c:s mov_text out.mp4`
```
Video, StreamOrder:0, ID:1
Audio (eng), StreamOrder:1, ID:2
Audio (ita), StreamOrder:2, ID:3
Audio (fre), StreamOrder:3, ID:4
Text, StreamOrder:4, ID:5

And this is the end result when importing the same subtitle to the same .mp4 with mp4box:
`mp4box -add subtitles.srt in.mp4`
```
Video, StreamOrder:3, ID:1
Audio (fre), StreamOrder:0, ID:4
Audio (ita), StreamOrder:1, ID:3
Audio (eng), StreamOrder:2, ID:2

] | When trying to encapsulate H.266/VVC content into an MPEG-TS file, there seems to be 2 problems with the output:
1) Access unit delimiter appears without the stop bit (00 00 00 01 00 a1 **a0**), This appears throughout the stream (Gpac adds aud units to every frame)
2) Stream type seems to be off, according to "ISO/IEC 13818-1:2019 DAM 2 Carriage of VVC in MPEG-2 TS", it should be 0x32, whereas GPAC creates 0x33 (And from looking at the source code, it can choose between 0x33 or 0x34)
*) GPAC version used: 1.1.0-DEV-rev499-g3c03581d-master
Steps to reproduce:
1) Download a YUV file
2) Encode several frames by using a reference encoder (verified with VQ analyzer)
3) Pack to .ts file by using: gpac -i suzie_16_frames.266 m2tsmx:pes_pack=none:first_pts=1000000 @ -o suzie_16_frames_new.ts
4) Observe faulty stream type and access unit delimiter lacking stop bit by viewing hex dump / ts analyzer
Snippet from notepad++:
The aud should end with 0xa8, according to the standard. Once this value is manually changed, the analyzer can open the bitstream (Once it's stripped back from .ts to .266, maintaining the aud units)

I'm creating MPEG-DASH-SRD content using following guide.
https://github.com/gpac/gpac/wiki/HEVC-Tile-based-adaptation-guide
I have different versions available in DASH content and I'm creating a final video by selecting appropriate quality for particular tile by concatenating the tracks on the base.
MP4Client is playing the final video properly as per my requirement.
But codec information is missing in the metadata.
As per steps in the above mentioned guide codec information is present in the hvc file.
After performing following step codec information is not added in the mp4 video.
MP4Box -add video_tiled.hvc:split_tiles -new video_tiled.mp4
Do I need to follow some other steps which are not mentioned in the guide during the packaging of the video? | Codec information missing after packaging of HEVC video | DASH | 360 video | https://api.github.com/repos/gpac/gpac/issues/1683/comments | 33 | 2021-01-26T11:29:01Z | 2021-03-25T06:18:57Z | https://github.com/gpac/gpac/issues/1683 | 794,156,530 | 1,683 |

] | Hello, I am trying to package and DASHify an IMSC1 profile ttml file using the following commands:
# To wrap the ttml file around and the mp4 container:
mp4box -add <imsc1_file>.ttml -new <imsc1_ttml>.mp4
#To segment the mp4 file into 1s segments:
mp4box -dash 1000 -profile live -rap <imsc1_file>.mp4 -out <output_dir>/MPD.mpd
I understand that MP4Box currently supports only the EBU-TTD-TTML profile. As I mentioned earlier, my document has the IMSC1 profile and consists of several regions active at the same time to test various ttml parameters.
The problem I am encountering is that MP4Box currently repeats the entire document in each sample without a different start and end time and without the ‘redundant’ flag. This means the player does not know that it should just extend the presentation of the previous sample.
In practice this can impose a lot of strain on the decoder since it will have to parse and decode the same TTML document repeatedly. In theory I could break the TTML document into smaller ones but that requires a lot of overhead in order to break it up and package each file individually.

Hello,
It might not be an issue but I was wondering if it's possible to actually merge those segments of similar m3u8 as :
https://content-ause2-ur-discovery1.uplynk.com/ce6f6a0e4c0c440ca22f05e5e14a82a4/f.m3u8?pbs=294fa09c22a04e4fba447b20c5ee7f0c
into one mp4.
Those segments are AES 128 encrypted with IV in every segment.
I tried using MP4Box following what was written in here "https://github.com/gpac/gpac/issues/1236" but I was unsuccessful with it.
Any Help would be appreciated.
Thanks in advance

mp4box.exe -add \\server\d\video.264 \\server\d\muxed.mp4
results in error:
[Importer] No valid track to import in input file "\\server\d\video.264"
Error importing \\server\d\video.264: Feature Not Supported
This used to work in an older version which I have: 0.7.0-rev0-gbd5c9af-master
Checked with both gpac-1.0.1-rev0-gd8538e8a-master-x64.exe and gpac-1.1.0-DEV-latest-master-x64.exe.
(In my original post, there are two backslashes before "server" as required. The editor removes one)

Step to reproduce:
1. create an random audio file
```
ffmpeg -f lavfi -i "sine=frequency=1000:duration=10" -ac 8 test.mp4
```
2. use that audio file to create mpd and output
```
MP4Box -dash 2000 -rap -frag-rap -bs-switching no -profile "onDemand" "test.m4a" -out "output1.mpd"
```
```
mv test_dashinit.mp4 test_dashinit.mp4.bak
```
```
MP4Box -dash 2000 -rap -frag-rap -bs-switching no -profile "onDemand" "test.m4a" -out "output2.mpd"
```
I've notice that md5 of `test_dashinit.mp4` and `test_dashinit.mp4.bak` are not identical, I've assumed we use some sort of timestamp when create dashinit.
Is there anyway I could eliminate that timestamp and make it identical ?

"gpac",
"gpac"

```
mp4box.exe -add input.mp4 -add children.srt:hdlr=sbtl:group=2:layer=-1:name=MyCaptions -new output.mp4
```
You can use any mp4 file for this example. The `children.srt` file contains:
```
1
00:00:00,000 --> 00:00:05,000
We have the words "children" and "Group" here.
2
00:00:05,000 --> 00:00:13,000
We have the words "children" and "OrderedGroup" here.
3
00:00:13,000 --> 00:00:22,000
We have the words "children" and "Layer2D" here.
4
00:00:22,000 --> 00:00:32,000
We have the words "children" and "Layer3D" here.
```
The problem is that mp4box uses the `btplay` filter to read the SRT file because of the probe code in `load_bt_xml.c`.
```c
} else if ( strstr(probe_data, "children") &&
(strstr(probe_data, "Group") || strstr(probe_data, "OrderedGroup") || strstr(probe_data, "Layer2D") || strstr(probe_data, "Layer3D"))
) {
mime_type = "application/x-bt";
```
It should be using the `txtin` filter (which it uses for `*.srt` files).
There are several ways to fix this problem. For example, if a file has the `.srt` extension then you might prefer the `txtin` filter over `btplay`. | Problems inserting subtitle (*.srt) files that contain certain pairs of words (e.g. "children", "Group") | https://api.github.com/repos/gpac/gpac/issues/1656/comments | 3 | 2020-12-10T19:51:16Z | 2020-12-10T22:54:13Z | https://github.com/gpac/gpac/issues/1656 | 761,561,701 | 1,656 |

Hello,
I appreciate the quick fix in https://github.com/gpac/gpac/issues/1650 but, sadly the timestamps still seem broken
The .srt timestamps should be in the form of
[hours]: [minutes]: [seconds], [milliseconds]
While the output I get from Mp4box with -srt flag are in that form missing the Hours part and the "." should be "," :
00:06.000 --> 00:06.040
they should be :
00:00:06,000 --> 00:00:06,040
Also for the embedded webvtt, the Timestamps seems broken:
00:06.000 --> 00:06.040 position:10%,start line:85% size:80%
they should be:
00:00:04.040 --> 00:00:06.040 position:10%,start line:85% size:80%
Thanks again !

Is there a tool to use or is it all manual ? And if so, please, how to proceed ?
Sorry for this dumb question but it's been 3 days and haven't been able to find specific docs about it other than [this one](https://github.com/gpac/gpac/wiki/Common-Encryption) that explains what it is, but not how to produce one :/

Hello,
I am trying to create live dash streaming of tiled HEVC. I have been doing extensive reading, and I believe I might be on the right path, but I cannot correctly dash this.
I am doing the following every X seconds (loop) => **[ffmpeg records video from /dev/videox] -> [kvazaar tiles] -> [MP4Box packages it]**
```
rm -R dash_output/*
i=0
while true;
do
ffmpeg -f v4l2 -framerate 30 -video_size 3840x2160 -i /dev/video0 -an -f rawvideo -pix_fmt yuvj420p -t 00:00:02 - | kvazaar -i - --input-res 3840x2160 -o videos/hevc_live_output.hevc --tiles 3x3 --slices tiles --mv-constraint frametilemargin --bitrate 128000 --period 30 --input-fps 30
MP4Box -add videos/hevc_live_output.hevc:split_tiles -fps 30 -new videos/live_video_tiled.mp4
done
```
By the end of this, I have a new MP4 file I want to dash:
```
MP4Box -dash-ctx dash_output/dash-live.txt -dash-live 2000 -run-for 2000 -profile live \
-mpd-title "DASH-LIVE stream" -ast-offset 12 -no-frags-default -rap -frag-rap \
-insert-utc -mpd-refresh 2000 -time-shift 1200 -min-buffer 2000 -bs-switching no \
-out dash_output/dash.mpd -subsegs-per-sidx -1 videos/live_video_tiled.mp4:role=main
```
_I am running this on a loop for video recordings of **2 seconds each**._
**At the output of each dash run I get:**
```
[Dasher] No template assigned, using $File$_dash$FS$$Number$

```
Finally, when I try to play this MPD back on gpac I always get the same error:
```

Is this the correct way of doing this? Is this simply not supported?

Actually, gpac 1.0.1-rev0-gd8538e8a-master (.deb) seems broken for Debian stretch (oldstable, available libav\*57 are older than the ones required), Debian buster (available libav\*58 are too new for gpac), ubuntu > 18.04 (same problems).
*So, the .deb link should only report Ubuntu and *18.04*, if possible.*
## Reproducibility
The following is the only working docker image able to install gpac (it should be the same for complete OSes)
```Dockerfile
FROM ubuntu:18.04

RUN apt-get update && apt-get install -y ./gpac*.deb
```
Replacing the base image tag with 19.04, 19.10, 20.04, 20.10 shows how gpac cannot be installed there.
The same happens using either debian:stretch or debian:buster, with the `contrib non-free` source repositories enabled. | Specify Linux distributions with versions and environments on which realeases are built | https://api.github.com/repos/gpac/gpac/issues/1646/comments | 3 | 2020-11-21T18:40:26Z | 2023-01-03T13:41:37Z | https://github.com/gpac/gpac/issues/1646 | 748,075,483 | 1,646 |

I have been trying to use cbcs encryption on fmp4 content to be played by Apple devices. Testing it in Safari with jwplayer
Basically player isn't playing with error: "An error occurred when attempting to decrypt the Fairplay stream with the session key. Equivalent to Safari's "webkitkeyerror" event."
I checked with another packager, using the same keys and encryption, and the content plays out fine. I also check the content inside mdat and it is exactly equal to MP4box output, every byte.
This leads me to believe it may be something related with the header boxes before mdat?
senc box seems a match too, so I don't understand what might be the problem with the key in mp4box
Could some important config on drm.xml be missing? I tried to look for info on it but didn't find anything that pointed to a problem in my drm.xml
I also tried to decrypt the file output from -crypt with -decrypt and got the error:
**mp4box.exe -decrypt drm_cbcs.xml -init-seg 01.mp4 cbcs_constantIV.m4s -out decrypt_cbcs.m4s**

Error IsoMedia File is truncated while instantiating filter mp4dmx
[Decrypter] Cannot load demux filter for source file

Attached the drm.xml, the clear header file, clear chunk, mp4box cbcs chunk and the comparison chunk that works.
I can attach content for a complete playout if needed.
