AMD Radeon Pro WX 5100 doesn't have hardware encoding #114

Closed iandol closed 3 years ago

I have the latest Mesa VA-API drivers installed, but OBS Studio installed as a snap cannot use them, it defaults to software only.

  Mesa VA-API video acceleration drivers

The OBS snap doesn't use the host VA-API drivers. Please run obs-studio.vainfo and paste the output here.

Hi @flexiondotorg, thanks for the reply!

Here is the output:

But only software encoding is available.

If you apt install vainfo what does vainfo on the host display?

iandol commented 3 years ago

I am currently not close to that machine, will test it early next week, thanks for your feedback.

I did manage to ssh into that machine:

So, the VA-API capabilities of the snap match your host, which implies your GPU should be able to encode H.264 (Main and High profiles). How have you configured the encoder in OBS? Please attach a screenshot :+1:

@flexiondotorg -- thanks, here are my recording settings (basically the defaults):

You need to change the "Output Mode" to "Advanced".

Then use FFMPEG VA-API as the Encoder to access hardware-accelerated encoding.
