Add hwdec option #21

Closed NicolaSmaniotto closed 2 years ago

NicolaSmaniotto commented 2 years ago

This adds the option for the user to choose a value for the --hwdec= parameter for mpv subcalls.

The default is kept "no", as it currently is.

From my testing, it can be enabled without issues because mpv is able to gracefully fall back to software decoding.

I personally set it to auto-safe, and it almost halves the time to generate the thumbnails (of course, for encoders supported by my processor).

Thanks! It seems to make no difference for my CPU though (i7-7500U)

This is strange, do you see the hardware decoder when pressing I?

Yes, it also shows vaapi. The duration for thumbnail generation stays the same. I'm on mpv 0.34.1-4 on Arch Linux. Log doesn't show anything useful.

I see. Maybe your processor is already powerful enough to move the bottleneck elsewhere.

My 4th gen i5 certainly needs the help.

Have a nice day :)
