On my laptop vlc cannot accelerate hardware some avi mpeg videos that are played in jerky mode.
When this problem happens I get the following output on the console from which I've launched vlc:

VLC media player 3.0.10 Vetinari (revision 3.0.10-0-g7f145afa84)
[0000558de8dea5b0] main libvlc: Esecuzione di vlc con l'interfaccia predefinita. Usa 'cvlc' per utilizzare vlc senza interfaccia.

[0000558de8eb2430] main playlist: end of playlist, exiting
QObject::~QObject: Timers cannot be stopped from another thread

In the past (months or a couple of years ago) the same files played correctly with vlc.

My laptop is an asus n752vx with i7-6700hq, 16GB RAM, nvidia 950M with proprietary drivers set up in order to always use the discrete card instead of the intel one and with prime enabled using nvidia-drm.modeset=1 and this is mine xorg.conf:

Section "Module"
Load "modesetting"

Section "Device"
Identifier "nvidia"
Driver "nvidia"
BusID "PCI:1:0:0"
Option "AllowEmptyInitialConfiguration"

Additional info:
* package version(s) 3.0.10

Steps to reproduce: try to play some specific .avi mpeg coded files which previously used to work
This task depends upon

I cannot share those files, but if needed I can try to execute all the tests you need to identify from where the issue arises.
