Not sure how to resolve this...

Have a video which is fine on mpv:
(+) Video --vid=1 (*) (h264 640x360 30.000fps)
(+) Audio --aid=1 (*) (aac 2ch 44100Hz)

but I get only good audio and psychedelic banding under vlc or kodi
with vlc the following errors:
$ LANG=C cvlc vid.mp4
VLC media player 3.0.6 Vetinari (revision 3.0.6-0-g5803e85f73)

Any ideas on how to get vlc and kodi to stop puking on h264?  I also have similar problems when trying to watch
internet tv on my freebox.

Which acceleration options are you specifying in mpv? Also please use [ code ] tags for posting command outputs.

If I'm reading that right you aren't specifying anything, so mirror that and disable hardware acceleration in VLC/Kodi

Hardware decoding should actually work on this GPU with the nouveau driver, by installing nouveau-fw from AUR. At least in theory. You also need mesa-vdpau (for VDPAU decoding) and libva-mesa-driver (for VAAPI decoding).

But in general, if you have playback problems, the first thing to do is what V1del says, disable hardware decoding. It's off by default in mpv for exactly this reason, because it can be flaky. Software decoding is much more robust.

firstly, turning of materiel decoding allowed to see the video correctly. That was good.
then, installing libva-mesa-driver and turning back on automatic materiel decoding
gave a much better rendition.
Thanks for the hints!
