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?
Check using e.g.
topfor your CPU (nvidia-smioramd-smifor your GPU) or System Monitor on KDE if any of your resource is being maxed out. If so then most likely you found the culprit.Regarding what the actual codec is being used you can use
ffprobebut anyway what matters if resource bottleneck and thus if you can have hardware acceleration for it.It’s probably worth investigating so that you don’t keep on getting video files too big for your computer to handle. I imagine it’s something very high resolution with very recent compression. If so, look for something less demanding, e.g. x265 720p and if that’s still leading to performance hiccups the older x264 720p or even 480p.
It’s rare that the media player itself, e.g. VLC or mpv, actually is the bottleneck.
