Segfault mit nvidia-drivers 550.67 und softhdcuvid

heifisch · March 28, 2024 at 4:37 PM

ich habe mal nvidia-drivers 550.67 mit softhdcuvid ausprobiert, bekomme allerdings einen Segfault.

kernel: 6.8.2

ffmpeg: 6.1.1

nvidia-cuda-toolkit: 12.3.2

Hier der bt:

Der Test ist wahrscheinlich noch zu früh, aber vielleicht kannst Du ja das Problem erkennen und einen Patch machen.

Ich würde auch wieder Testen.

Danke und Gruß

Hab ich auch schon bemerkt, bin aber froh, daß softhdcuvid/libplacebo überhaupt mal mit nvidia-545 funktioniert. Das softhdcuvid scheint mit dem Cuda-12.4 noch nicht zu wollen.

Am besten bei 545 und cuda-12.3 bleiben. Mein libplacebo ist libplacebo-349, das funkt noch.

Ja, ich gehe gerade wieder zurück...

Tja ich verstehe nicht waurm NVIDIA immer wieder das eigene API kaputt macht. Ich habe es schon lange aufgegeben immer dem neuesten Nvidia Treiber hinterher zu laufen. Wenn der 545 geht dann sollte man dabei bleiben. Die neueren Treiber bringen eh nix in Sachen performance oder features.

lnj · March 29, 2024 at 10:18 AM

Fedora 39, ffmpeg 6.1.1, Nvidia 550.67, kernel 6.7.10.

No libplacebo.

Softhdcuvid works without crash.
