VLC on Raspberry freezes with waiting decoder fifos to empty

[avu2]

VLC on Raspberry Pi4B randomly freezes when loop playing 1920x1080 AAC, H.264 .mp4 videos with "waiting decoder fifos to empty". May happen after hours or after a few minutes following a reboot.

Any help or workaround wellcome

Aborted with CTRL-C, need to reboot for VLC to play any new video

[Rémi Denis-Courmont]

If you need to reboot the device to carry on, then the error must be at a lower level (kernel device driver or firmware), and there is probably little or nothing to do here.

That's what I think also but I gave it a try, you never know ... No answer on raspberry support forum. Merci bien
