Bug#1112130: vlc: cannot play av01 video
Package: vlc
Version: 3.0.21-10+b1
Severity: important
I've downloaded the following video in webm format from YouTube:
https://www.youtube.com/watch?v=ar5toq-E-5M
VLC opens a window with the right size (though it doesn't fit
on my screen due to the window decorations: this is 3840x2160),
but cannot display anything: this is entirely black.
Audio is fine.
In the terminal, I can see:
libva info: VA-API version 1.22.0
libva info: Trying to open /usr/lib/x86_64-linux-gnu/dri/iHD_drv_video.so
libva info: Found init function __vaDriverInit_1_22
libva info: va_openDriver() returns 0
libva info: VA-API version 1.22.0
libva info: Trying to open /usr/lib/x86_64-linux-gnu/dri/iHD_drv_video.so
libva info: Found init function __vaDriverInit_1_22
libva info: va_openDriver() returns 0
[00007f8010ca70f0] avcodec decoder: Using OpenGL/VAAPI backend for VDPAU for hardware decoding
[00007f8010ca70f0] main decoder error: buffer deadlock prevented
According to the media information, the video codec is
AOMedia's AV1 Video (av01).
Firefox can play this video (by opening the webm file directly,
without going via YouTube). The FFplay media player (ffplay)
can play it too.
Note that I could play videos from the same YouTube channel with VLC
in the past (a few weeks ago). But I don't know whether something has
changed.
