Why won't my laptop play webm files? Browsers can play but browsers are a different thing. mpv/vlc/mplayer just crash
💀
@GNUxeava
Any chance the file(s) in question are corrupted in some way?
@GNUxeava
Or maybe it's trying to use hardware decoding on them, but it's faulty because of drivers or something.
@GNUxeava
Try disabling hardware acceleration in VLC, see if it works.
@GNUxeava
Launch VLC from a terminal, open the file, and watch the output in terminal for error messages that might help troubleshoot.

What stumps me is that it's not just VLC, but also mpv... This kinda indicates that it's either a problem with hardware acceleration or drivers.
When you tried disabling hardware acceleration, did you close VLC and reopen it? (I'm not entirely sure if VLC manages to disable that on the fly). Also, you can try changing the video output (from automatic, to OpenGL or something else).
Is this a problem that has developed recently? Also what GPU? AMD/Intel/Nvidia?
@GNUxeava@fedi.absturztau.be @GNUxeava@mk.absturztau.be
Do you have any opus files lying around, see if it's specifically the video or audio streams that are causing this.
@GNUxeava@fedi.absturztau.be @GNUxeava@mk.absturztau.be
Well that's interesting... your VLC might be borked in multiple ways then, cause my VLC plays opus just fine.
But at least we're pretty sure now that it's the video stream that's causing the issue.
@GNUxeava@fedi.absturztau.be @GNUxeava@mk.absturztau.be
Then maybe it's something wrong with your distro. Try going to whatever support forum they have.
Amber (@amber@toot.site)
@abloo@fedi.absturztau.be @alyx@gameliberty.club @GNUxeava@fedi.absturztau.be that is what I have been doing the entire time
@GNUxeava@fedi.absturztau.be @GNUxeava@mk.absturztau.be
I'm running out of ideas... try live booting into a different distro, see if it will play the files with whatever video player & drivers it has by default.
