How to get HEVC VAAPI hardware encoding to work on FFMPEG?

Hello,

How can I get HEVC VAAPI hardware encoding to work on FFMPEG?

I installed all of the AMD proprietary drivers, it seems like I would need the open source MESA drivers, but I believe MESA drivers are already installed by default since this command:

glxinfo | grep "OpenGL vendor string" | cut -f2 -d":" | xargs

shows:

Mesa/X.org

Are there any articles or links which explains on how to get HEVC VAAPI hardware encoding to work on FFMPEG?

Thanks.

I was using the terminal via the XRDP and XRDP uses the open source mesa driver.

When logging into using a regular LCD monitor or using "nomachine" remote desktop, and using the terminal from there, it will show AMD (the proprietary AMD's GPU driver)...

Either way, would like to know how I can get HEVC VAAPI hardware encoding working on FFMPEG.

I tried installing "obs-hevc-vaapi" AUR package and like many before me had said it does not build, which happened the same to me.

Thanks.

It depends, what the name of the encoder is. Ans maybe of which driver you're using.

I have an Nvidia card, there I use ffmpeg with:

ffmpeg -hwaccel vdpau  -i INPUTFILE.mkv   -vcodec hevc_nvenc -profile:v main -level:v auto -preset:v default     -c:a copy   -f matroska  OUT.mkv

You can also use option -map 0:0   -map 0:1 for each stream. Check streams of file with

ffprobe FILENAME

Your your AMD graphic ard, check the outputs:

ffmpeg --help
ffmpeg -hwaccels
ffmpeg -encoders
ffmpeg -encoders | grep -i 265
ffmpeg -encoders | grep -i 264

The h265 graphic card encoder for my nvidia is hevc_vaapi.
The h264 graphic card encoder for my nvidia is h264_nvenc.

I have no AMD card, so I cannot say which one you have to choose.

The AMD encoder are:
AMD Encoder: Video Code Engine (VCE) (obsolet)    https://en.wikipedia.org/wiki/Video_Coding_Engine
AMD Decoder: Unified Video Decoder (UVD) (obsolet)   https://en.wikipedia.org/wiki/Unified_Video_Decoder
New/current: UVD and VCE were succeeded by Video Core Next (VCN)   https://en.wikipedia.org/wiki/Video_Core_Next
So I think you have to look at ffmpeg -encoders output, if there is something with VCN

Check also the tables in:   https://en.wikipedia.org/wiki/Video_Coding_Engine

hevc_vaapi is not specific to nvidia but useful for all cards.

Check https://wiki.archlinux.org/title/FFmpeg#VA-API

Oh, I confused hevc_vaapi with hevc_nvenc, sorry.
