the x264 av1 file plays only audio on vlc but works with flaws on mpv: on mpv I get audio and video, but every 5 to 6 seconds it’s like instead of getting 24 fps I get 22, the user noticing the missing frames.
Is this a hardware issue? software?
debian 12.11, vlc 3.0.21 flatpak, mpv 0.40.0 flatpak
what do I do?
Is it x264 or AV1? They are two completely different codecs. If it’s AV1, you may not have hardware acceleration since it’s fairly new. It takes a lot of power to software decode AV1 and you will get dropped frames if the CPU can’t keep up.
This right here is your issue, OP. Most likely is AV1 and cant decode it fast enough.
