Does ZM 1.30.x use hardware acceleration?

[Kiwijunglist]

Hi

I'm a bit confused how to enable hardware acceleration.
I have nvidia-smi working and fffmpeg -hwaccels gives me vdpau / vaapi / cuvid
How do I enable using cuvid in zoneminder?

Thanks
Mike

This took a bit of doing... Here are my tech notes for those who follow:

Now the test. I like the 50% savings!

Hi I have ffmpeg -hwaccels gives me vdpau/vaapi/cuvid ... however I'm not sure how to implement this in to zoneminder, like where and what do i put in the ZM GUI?

I tried
Monitor -> Source -> DecoderHWAccelName = cuvid (and cuda / vaapi / vdpau)

But I still don't see that it is using HW acceleration, and I don't see any gpu processes listed under nvidia-smi (like i would when plex uses HW transcoding)

Thanks
