VLC problems following recent updates
by pchristy from LinuxQuestions.org on (#6EB6A)
System: Pi400, Slackwareaarch64-current (up to date), Pi-kernel, VLC-3.0.18
Something recent has broken VLC's ability to playback h264 files. This is a particular issue as I use Kaffeine (which uses libvlc) to watch TV occasionally, and I can no longer watch HD channels (SD is fine!).
I'm also unable to play local H264 files.
Smplayer+MPV, standalone MPV and ffplay all play h264 files fine, although cpu usage seems to have gone up (around 80% on all 4 cores). It seems as if something specific has broken VLC.
I've recompiled VLC, ffmpeg and x264 to no avail, and I've now run out of ideas!

[0000007f78c0ba20] avcodec decoder error: more than 5 seconds of late video -> dropping frame (computer too slow ?)I'm using the "automatic" or "opengl" output, as recommended for this application. I don't think the va/vdpau errors are significant as I've seen these previously without issue. What I don't understand is the h264 errors, when mpv, ffplay, et al, play back just fine!
Anyone got any ideas?
