3.0.21 some mkv files, no audio

Postby general_user » 12 Jun 2024 02:54

In a freshly updated version 3.0.21 some mkv video files would have no audio. In Tools/Codec information/Statistics showed Audio decoded but not played. Backgrading to ver. 3.0.20 restored audio

What is your OS ?
What is your hardware, especially CPU and GPU ?

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.

Windows 10 64bit, i7- 5700, unknown gpu, it's someones work station and I have very limited access. Further testing unlikely. Sorry!

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

If needed cut it with DGsplit and read here about how to do it:

200 MB max should be enough but a full complete short file is better.

hello @Lotesdelere

I have the problem and investigate with a debugger attached.

The problem should be fixed by https://code.videolan.org/videolan/vlc/ ... 0ef6c35309
But the fix submitted 1 year ago was not included in a release yet.

Can confirm I had the exact same issue. Had to roll back to version 3.0.20 to resolve it.

Last time I have checked, the fix was merged to be in the next release of the branch 3.x (should be 3.0.22).
But I have no idea when that might happen
