no audio on some Twitter videos

Postby i_hate_guis » 03 Jul 2023 03:11

An issue has shown up only recently on some Twitter videos downloaded with yt-dlp (a bit more challenging the last couple of days, but that has nothing to do with this problem). For a small percentage of Twitter videos (again, I have never seen this until a few weeks ago), VLC will play the video perfectly, but won't play any audio at all (other media players, such as mpv, will play both video and audio correctly).

In attempting to determine the cause of this issue, I have a possible clue. It appears that the videos with no sound output display a different muxer in mediainfo. For example (obscuring some irrelevant details):

Sound working:

Code: Select all

Audio ID : 2 Format : AAC LC Format/Info : Advanced Audio Codec Low Complexity Codec ID : mp4a-40-2 Duration : 1 min Bit rate mode : Variable Bit rate : 128 kb/s Channel(s) : 2 channels Channel layout : L R Sampling rate : 48.0 kHz Frame rate : 46.875 FPS (1024 SPF) Compression mode : Lossy Stream size : 0.90 MiB (10%) Title : Vireo Ears v2.9.1 Encoded date : 2023-06-30 00:00:00 UTC Tagged date : 2023-06-30 00:00:00 UTC
Sound not working:

Code: Select all

Audio ID : 2 Format : AAC LC Format/Info : Advanced Audio Codec Low Complexity Codec ID : mp4a-40-2 Duration : 1 min Bit rate mode : Variable Bit rate : 128 kb/s Channel(s) : 2 channels Channel layout : L R Sampling rate : 44.1 kHz Frame rate : 43.066 FPS (1024 SPF) Compression mode : Lossy Stream size : 0.90 MiB (10%) Title : Twitter-vork muxer Default : Yes Alternate group : 1
VLC will play the audio if I remux the second video (with mkvmerge, for example), but obviously, I believe that VLC should play these videos correctly without remuxing, particularly since other media players can. I (or rather the less sophisticated user who discovered this) have VLC 3.0.18 (compiled from source).

Any thoughts on this?

Please open Tools -> Messages (set Verbosity to 2) before you start the playback, and then paste the full resulting log here or on Pastebin.com or on Justpaste.it if it's too long.

Also upload a short sample of your original problematic file to WeTransfer.com or Disroot.org and then post the link to the file here.

I don't know about the maximum length (it doesn't seem too long to me), so I will paste the messages here). Update: I just received a message that a past has a maximum number of characters of 5998, which means I have to use a pastebin.

You can find the log here:

Just cutting part of the file from the beginning produced errors on playback (partial file, error reading packet), and I wanted to avoid any processing that might change the containers, so I just uploaded the whole thing (about nine minutes and 150 MB).

Yes, I can reproduce the issue with the demuxer set to automatic, but it's playing fine when forcing the demuxer to Avformat.

You should create a new report ticket on the VLC issues tracker with your above report, the link to your sample file and the link to this thread:
https://code.videolan.org/videolan/vlc/-/issues

I signed in to my GitLab account, and then went to https://code.videolan.org/users/sign_in . When I select Gitlab.com and allow "Authorize VideoLAN Gitlab to use your account?," I get the message: "Signing in using your GitLab.com account without a pre-existing GitLab account is not allowed." The page https://gitlab.com/-/profile/applications does show "VideoLAN Gitlab" as an authorized application, but the videolan.org page won't let me log in.

Any ideas?

I know, there are plenty of similar reports on the forum about logging in to this site but it looks like no one from the staff has ever replied or done anything about this issue.
I guess you need a specific new account for code.videolan.org.

Maybe you can send an email to videolan (at) videolan.org about the issue.

Or join the IRC channel:

Server: irc.libera.chat
Channel: #videolan

People on the IRC channel confirmed the disabling of account creations due to spam.

Can someone with an account file an issue about this?

Hello,
was this resolved?

I have a similar issue with downloaded twitter videos (via twitter video downloader extension)
Usually they work fine, but everyone now and then, like 15% of them,
have issues with the audio and a few of them will also just cut of after a few seconds of playback.
Those files play without issues in any other player or browser.
Here an example log of a file that plays without the audio.
And a link to the original file https://we.tl/t-Bxm4yBufmb

Thanks for the help.
