"gpac",
"gpac"
] | Hi,
I am trying to stream 360 tiled video content. I am streaming video from 360 camera with rtmp to nginx server and generating video content with this:
gpac -i rtmp://localhost/live ffsws:FID=S -+kvazaar-params=tiles=3x3,slices=tiles,mv-constraint=frametilemargin,rc-algorithm=lambda enc:SID=S:c=libkvazaar:b=1m:fintra=1:rc @ tilesplit:FID=1 enc:SID=S:c=libkvazaar:b=200k:fintra=1:rc @ tilesplit:FID=2 -o live.mpd:SID=1,2:dmode=dynamic
so this produces mpd file and a lot of m4s files. I would like to understand the background of this command (what are the proccesses between input file and mpd output) and I wasn't been able to find some documentation, so I am wondering if you could provide me some information or documentation file.
Secondly I would like to stream generated mpd file and play it in mp4client. I found this: https://github.com/gpac/gpac/wiki/Tiled-Streaming#how-to-stream-360-video-content, so if I understand correctly, all I should do is
m4pclient http://localhost/live.mpd#360LIVE
and this produces hls stream? So on the client side I would select an input http://localhost/live.mpd and it should play?
Thanks for all the information

] | Hello,
I have a problem with hls playlists,I don't know if this is a bug, or if I am missing an option somewhere.
I tested with 1.0.1, and the last master version.
I tested this command
```bash
MP4Box -dash 4000 \
-profile onDemand \
transcoded_720.mp4#video \
transcoded_720.mp4#audio \
-out manifest.m3u8
```
I tried with the gpac tool directly too.
The resulting playlist is playable with vlc and ffplay for example.
But it fails with videojs or hls.js, only the first segment is played.
Here is the resulting playlist for the video track:
```

If I analyze the file with your tool at https://gpac.github.io/mp4box.js/test/filereader.html,
In the segment view I get:
| Segment | referenced_size | segment offset |
|---------|-----------------|---------------|
| 0 | 930114 | 1836 |
| 1 | 743971 | 931950 |

| 14 | 514508 | 8041463 |
| 15 | 258588 | 8555971 |
From what I see the segment offset from the online tool doesn't match with the byte range offsets in the playlist.
It seems to be missing 876 bytes for each range in the playlist.
If I replace the byte range starting offsets in the playlist with the ones reported by the online tool it works again
with videojs and hls.js.
Here is the xml mp4 box dump of the file:
[gpac.md](https://github.com/gpac/gpac/files/6915816/gpac.md)
Is it intended to be like that, or is there a specific option to make it work ?
Regards,
Romain

] | Hello,
I'm not sure if this is a bug, a missing feature or a user mistake.
1.0.1 MP4Box GPAC version is used (Windows 64 bits installer)
I'm trying to mux some files (1 video stream, 2 audio streams (eng/fre) and 2 subtitles streams (forced/regular, both fre)).
The target players are VLC (3.0.11 on Windows) and AppleTV app (iOS device (14.6)).
VLC player works as expected : It play the video track, the non-disabled audio track, and the forced subtitle by default.
iOS player play the video, an audio track and the regular subtitle : Forced subtitle is NOT shown (and don't appears in the dropdown list on the player, but this may be intented).
As far as I know (from [QuickTime File Format Specification](https://developer.apple.com/library/archive/documentation/QuickTime/QTFF/QTFFChap3/qtff3.html)) :
- A dedicated forced subtitle track must have "All samples are forced" display flag (resulting in `0xC0000000`) :
> If this flag is set, the subtitle media handler treats all samples as forced subtitles, regardless of the presence or absence of a 'frcd' atom. This flag’s value is 0x80000000. If this flag is set, the Some Samples Are Forced flag must also be set (making 0xC0000000).
- Because of the previous assertion, I don't try to set the "Subtitle Sample Data" to "frcd"
- Subtitle track must be a media type of "sbtl" :
> Subtitle media is used to store text data used for subtitles in QuickTime movies. It has a media type of 'sbtl'.
To try to achieve this, I'm using the following command :
```
MP4Box ^
-tmp .\ ^
-inter 1000 ^
-add tmp-video.h264:lang=ENG ^
-add tmp-audio-fr.aac:group=1:lang=FRE ^
-add tmp-audio-en.aac:group=1:lang=ENG:disabled ^
-add tmp-subs-fr-regular.srt:group=2:lang=FRE:hdlr=sbtl:disabled ^
-add tmp-subs-fr-forced.srt:group=2:lang=FRE:hdlr=sbtl:txtflags=0xC0000000 ^
-chap tmp-chapters.txt ^
-new out.mp4
```
Both audio tracks are in a dedicated group (group 1) because it seems to be a common practice.
Both subtitle tracks are in a dedicated group (group 2) because it seems to be a common practice.
A given audio track is disabled (mandatory, because all un-disabled audio tracks will play simultaneously in Quicktime/iOS).
The regular french subtitle track is disabled, because it should not be played by default.
The forced french subtitle track has the "All samples are forces" flag. This should be always played, regardless of the "subtitle off" option is trigger by the user.
Handler of subtitle streams are set to "sbtl" (see #1573 ).
This result in the following mediainfo :

My m4a causes gpac to segfaults, for my use case this is easily worked around by using an aac file instead (many thanks for adding udta support to gpac 🥇 and making this easy).
```
$ gpac -i TOS-enAD.m4a inspect
Segmentation fault: 11
```
The inspect filter is only an example it segfaults when trying to remux too, we can see that MP4Box has no such problem:

Simply remuxing with ffmpeg to mp4 `ffmpeg -y -i test.MOV -map 0 -c copy test.Mp4` , the output is playable in WMP at work.
I'm attempting to achieve the same end with MP4Box `mp4box -add test.MOV -new test.mp4` , but the output is still not playable.
mp4box_only self compiled from gpac-1.0.1-rev0-gd8538e8a-master
Is this the expected result or am I missing option(s)? There seems to be minor changes to the metadata only, but not the same for each

When I pack srt subs into an mp4, Quicktime isn't recognising the subtitles, e.g. fairly minimal commands:
`gpac -i TOS.264 -i TOS-en.aac:#Language=en -i TOS-it.aac:#Language=it -i TOS-en.srt:#Language=en -i TOS-da.srt:#Language=da -o test.mp4`
`MP4Box -group-add trackID=2:trackID=3 test.mp4`
`MP4Box -group-add trackID=4:trackID=5 test.mp4`
`MP4Box -disable 3 -disable 5 test.mp4`
Side note, I couldn't see how to create the variant groups and disable selected tracks in the gpac command?
I think the problem is that the subtitles are `text:tx3g` not `sbtl:tx3g` but I couldn't see how to change that?
I'm trying to make a more complete test file with UDTA signaling for closed captions and descriptive audio.
I couldn't see how to specify UDTA tags with a string using gpac so instead used MP4Box (from example here https://github.com/gpac/gpac/issues/1606#issuecomment-706069929), but again I couldn't see how to specify both name and tagc in one pass so instead e.g.
`MP4Box -udta 1:type=tagc:str="public.accessibility.describes-video" -lang en TOS_enAD.m4a`
`MP4Box -udta 1:type=name:str="English (describes video)" TOS_enAD.m4a`

As a git noob I was unable to use the command `git clone https://github.com/gpac/gpac gpac_public` as recommended as it failed in Visual Studio 2019 and at the command line.
I suspect this is to do with the space before gpac_public, but not sure how to deal with it. What does it mean?

There used to be an issue with encrypted 5.1 audio reported here https://github.com/gpac/gpac/issues/1274. Now it works great for 5.1 encrypted audio in AAC codec, however, it appears that there still needs to be an extra adjustment for AC-3/EC-3 codecs under the same scenario as it reports just 2 channels instead of 6 in the generated mpd even in the latest nightly 1.1.0 GPAC version.
The unencrypted 5.1 audio in AC-3/EC-3 codecs is correctly reported as 6 channels, the hex value in AudioChannelConfiguration is `F801`, which corresponds to the FL, C, FR, LS, RS, LFE mapping. But encrypted audio reports `A000`, which to my knowledge is just basic stereo in 16-bit representation, the result is:
`<Representation id="2" mimeType="audio/mp4" codecs="ac-3" audioSamplingRate="48000" bandwidth="640000">
<AudioChannelConfiguration schemeIdUri="tag:dolby.com,2014:dash:audio_channel_configuration:2011" value="A000"/>
</Representation>`
The result can be verified with this sample content https://devs.origin.cdn.cra.cz/log/ac3.mp4 in unencrypted form and https://devs.origin.cdn.cra.cz/log/ac3enc.mp4 as encrypted.
Also when dashing the encrypted version, log reports the following notification `[iso file] Unknown box type dac3 in parent enca`. Interesting thing is that when encrypting EC-3 codec, the message still mentions `dac3` even though the box is actually `dec3`. The file was encrypted by mp4box. and both AC-3 and EC-3 should be supported in ISO format normally I believe. | Encrypted multichannel AC-3 audio declared as stereo after dashing | https://api.github.com/repos/gpac/gpac/issues/1859/comments | 1 | 2021-07-14T09:16:00Z | 2021-07-14T10:52:43Z | https://github.com/gpac/gpac/issues/1859 | 944,220,149 | 1,859 |

I'm using the command below that shows a static frame when I load it into [THEOplayer](https://www.theoplayer.com/ll-hls-test-page). I'm sure I'm doing something wrong, but as I've just touched gpac for the first time I'm not sure what options I should add to get a playable video stream.
**What command should I use to stream from my webcam to generate a ll-hls stream?**
```make
gpac -i av://:src=/dev/video1 \
@ enc:c=avc \
@ -o http://127.0.0.1:8080/live.m3u8:segdur=2:cdur=0.2:dmode=dynamic:rdirs=${tmp_dir}:reqlog=GET:llhls=sf

**Update**
After doing a couple more tests I've noticed that none of the experiments/tests I did works when I try to playback a video in Safari on an iPhone. This makes me wonder about the current state of the ll-hls implementation: is this supposed to work atm? Of course I still might be using the wrong command, though the commands that I use are based on the test-suite commands. | What gpac command to use for low latency hls (ll-hls) stream that captures from webcam? | https://api.github.com/repos/gpac/gpac/issues/1856/comments | 2 | 2021-07-13T10:44:26Z | 2022-01-14T09:50:17Z | https://github.com/gpac/gpac/issues/1856 | 943,161,499 | 1,856 |

I uploaded the audio, video, chapter files and the MP4Box and FFmpeg output files to [my google drive](https://drive.google.com/drive/folders/1X4xxJ5h8I6Ed00yc8sTIfJmDG-DnSpXL?usp=sharing)
The video stream was created using x264 and the audio was created using qaac.
Is this a bug or is something broken with the input files?

We compile the lastest Osmo4 project and find some issues:
We load the following video: http://download.tsi.telecom-paristech.fr/gpac/SRD/tears_of_steal/tos_srd_all.mpd.
And we call this method to switch the bit rate of dash.
```
gf_dash_switch_quality(ctx->dash, GF_TRUE, GF_TRUE);
```
It will take about 5 seconds to see the effect.
And we try to seek the time by calling the following method, then It will take about 5 seconds similarly.
```
gf_dash_seek(dash, 0);
```

Hello, I am trying to tile and dash using MP4Box and Kvazaar and have run into an issue. While I am able to get a playable tiled live DASH video through the steps available on [THIS](https://github.com/gpac/gpac/wiki/Tiled-Streaming) page the resulting video has no audio when played.
Here is the manifest it created when the dash command was run, and from a look, it seems like there isn't an audio stream included in it or the audio stream is getting set as video.
[Help_DASH.mpd.txt](https://github.com/gpac/gpac/files/6793477/Help_DASH.mpd.txt)
I was able to add an audio stream by using -add but MP4Box refused to DASH the file after adding it this way (no error, nothing in verbose output, just died).
Is there a separate way to add an audio stream for DASH, or am I missing a step in between from the origional instructions page?

I 'm playing 360 Video tiled streaming which is created by the following command.
mp4box.exe -dash 1000 -frag 1000 -profile live 10M.mp4 20M.mp4 30M.mp4 40M.mp4 -out "10x10\dash.mpd"
Could it possible to measure the merged viewport?
I saw the other people measured by VMAF and PSNR. #1713
But he used a complete MP4.
Could it possible to save the mp4 when I use the MP4Client to play the DASH ?

Hi there. I need to be able to programmatically split an mp4 file into equally sized (not duration) chunks. I found that the mp4box -splits command was the way to go for this. Please could you point me in the direction of the function which does this? I would like to wrap it using CGo so that I can call the function from a Go program instead of calling the executable from the command line. This way, the mp4box splits command will be compiled and packaged with the binary.
Where is the specific function located? | mp4box split function location | to generate cgo bindings for calling programmatically | https://api.github.com/repos/gpac/gpac/issues/1833/comments | 6 | 2021-06-27T10:20:27Z | 2021-07-01T14:06:16Z | https://github.com/gpac/gpac/issues/1833 | 930,897,240 | 1,833 |

Hi,
I'd like some helpm on linking a file which i am calling form a cusotm filter I'm trying to build:
I managed to call a `.o` from my filter by adding some flags to the compiler, but upon pulling changes I erased it and can't find how to get a shared `.o` to work witjh my custom filter, :(.
I'm using `ubuntu 20.04`, `gcc 8.4.0` and gpac up tp date with the master branch - so this [commit](https://github.com/gpac/gpac/commit/206ad0907cc1f56ef031b5e3b1e30136e721ba9f) -.
I've got my Makefile which is heavily inspired by the [dec_openhevc](https://github.com/gpac/gpac/blob/master/modules/dec_openhevc/Makefile), as it is module a filter.
My command to compile my filter into a library file is :
```sh
COMMAND = @gcc -shared -o ../../bin/gcc/gf_libTest.so ../../src/filters/ff_common.o read_test.o -lm -L/usr/local/lib -L/usr/local/lib -lavcodec -lavformat -lavutil -lavdevice -lswscale -lswresample -lavfilter -fsanitize=address -Wl,-z,defs -dynamiclib -L../../bin/gcc -lgpac -ldl -fsanitize=address -Wl,-z,defs -dynamiclib
```
which gives me an error :
```sh
/usr/bin/ld: ../../src/filters/ff_common.o: in function `ffmpeg_register_free':
ff_common.c:(.text+0xe7): undefined reference to `gf_fs_remove_filter_register'

Hi,

I am trying to use Kvazaar as a GPAC filter with input being rtmp live stream currently from OBS, but in future maybe from other camera.
I tried it with local mp4 file and it is working correctly (I got mpd file and a lot of m4s files). When I put just rtmp://myUrl/live instead of file.mp4 I got this:
and no output files, and when I add :dmode=dynamic at the end of the command, I get _*** buffer overflow detected ***: gpac terminated_ . Is there something else I should do if my input is live? Should I do it in other way? Basically I would like to split live video into tiles, encode tiles to different qualities, and play it while somehow telling which quality of each tile to use.
Thanks

Then, there is a [test](https://github.com/gpac/gpac/blob/master/src/isomedia/avc_ext.c#L2731) checking for the profile and if the profile is 100, the code will be calling [gf_avc_read_sps](https://github.com/gpac/gpac/blob/master/src/isomedia/avc_ext.c#L2737) while removing the 1st byte of the sequenceParameterSets buffer.

] | Software Version: `MP4Box - GPAC version 1.0.1-rev0-gd8538e8a-master`
OS Version: `Microsoft Windows [Version 10.0.19041.928]`
This is a bit of an odd one, I'm adding captions (SRT format) to existing MP4 files, the ones _not_ initially created by MP4BOX work fine. However, the 10 files that I processed with MP4BOX (was adding commentary tracks) previously, strange things happened to the track order.
My command line for building them initially was:
`mp4box -new "filename.mp4" -add "assets\filename.hvc:name=" -add "assets\filename.aac:name=:lang=eng" -add "commentary\filename.aac:name=Commentary with Cast and Crew:lang=eng:delay=0"`
This worked fine, but now adding captions with:
`mp4box "filename.mp4" -add "filename.srt:name=:lang=eng"`
It adds the captions but now the track order is putting the commentary first. The track number remains 3 but it appears second and most software defaults to it. Very strange. Weirder, the files that were encoded and muxed by Handbrake do not exhibit this behavior. (Although they only had the video and single audio track.)

I have an input mp4 file with audio and video, and when I pass it into gpac with the command below, I get a master playlist with 2 media playlist with 2 init files. But I want a single media playlist with a single init file, is this possible with gpac? What would I have to change in my command to make it work?
This is the command that I am using
gpac -i inputfile.mp4 reframer:rt=on @ -o live.m3u8:segdur=10:cdur=0.2:llhls=br:dmode=static

] | Hi, I have tried the python DASH client and it is amazing. The example works in the beginning but the windows will freeze with some blurred block as the figure shows when the resolution is changed but the terminal prints logs as normal. I wonder to know how to fix it. The libgpac version is `gpac-1.1.0-DEV-rev770-gc8edcaff-master-x64` and the OS is windows 10.
The second question is I want to do some processes of the frames such as scaling the frame or draw a rectangle in the frame after decoding the video and get the numpy array while disabling the playing window. After reading the document in the wiki, it seems that I need a custom filter but I can not run the example in the wiki and determine the position of the filter in the workflow. Would you mind providing an example more detailedly?
Thanks for your help.

] | Hello,
I am trying to use Kvazaar as a GPAC filter, but I cannot make it work.
I've compiled ffmpeg with following commands:
sudo apt-get update
sudo apt-get install ffmpeg
moved to ffmpeg folder
./configure --enable-libkvazaar
make
make install
I've installed gpac:
downloaded source code
moved to gpac folder
./configure --use-ffmpeg=local
make
make install
I used following command:
gpac -i rtmp://MyURL/live enc:c=libkvazaar:b=1m::kvazaar-params=tiles=3x3,slices=tiles,mv-constraint=frametilemargin,rc-algorithm=1 @ tilesplit @ -o dest
and the response I got was:
Unrecognized codec identifier in "enc" definition: c=libkvazaar
Failed to find filter "enc:c=libkvazaar:b=1m::kvazaar-params=tiles=3x3,slices=tiles,mv-constraint=frametilemargin,rc-algorithm=1"
No filter with similar name found, see gpac -h filters
When I type gpac -h filters I get this:
