using GPU transcoder acceleration without having X11 console loaded?

Added by Paul M about 3 years ago

my TVH server has an AMD Ryzen 4300GE so has a Vega GPU, I'm running it on Ubuntu 20.04-LTS

if I try use ffmpeg to transcode a recording it says there's no video device (running as root to avoid permission problems). Since this is running headless in a cupboard, I have no desktop installed so there's no desktop or X11 running.

heve you read this in your log

No device available for decoder: device type vaapi needed for codec mpeg2video.

AMD have very bad support for transcoding aka AMF
and your command line do not use correct commands
second:
your FFMpeg do not support it
https://github.com/markus-perl/ffmpeg-build-script
build more good FFMpeg ;)

I also tried the commands here:
https://trac.ffmpeg.org/wiki/Hardware/VAAPI

to initialise a device

so I will have a go at building ffmpeg as per your helpful suggestion, thanks

ffmpeg -hide_banner -hwaccels

helpful command ;) 
ffmpeg -hwaccel auto -i INPUT -c:v h264_amf OUTPUT

digging through the build output of ffpmeg

I noticed the ffmpeg build created two ffmpeg programs, the large one got copied to the /usr/bin, the other wasn't even executable so I made it executable but it failed like the other, only with even more verbosity

wrong command line

you say
FFmpeg use whatever you found hardware DECODER , convert Video Stream using h264 hardware ENCODER , some file
result error

you must say

FFMpeg open with wathever you found hardware DECODER SOURCE, convert Video Stream using h264 hardware ENCODER , write to file

I did try your command line, I can see it in my bash history, but I appreciate I've spammed this thread so here it is below. Why is ffmpeg unable to find libamfrt64.so?

RE: using GPU transcoder acceleration without having X11 console loaded? - Added by Paul M about 3 years ago

I installed the AMD official driver, having downloaded the tarball amdgpu-pro-21.20-1292797-ubuntu-20.04.tar.xz and using their installation instructions.

RE: using GPU transcoder acceleration without having X11 console loaded? - Added by Paul M about 3 years ago

I installed a load of other packages from the downloaded AMD driver pack, and got some libamf files:

# find / -iname "libamfrt64*" 
/opt/amdgpu-pro/lib/x86_64-linux-gnu/libamfrt64.so
/opt/amdgpu-pro/lib/x86_64-linux-gnu/libamfrt64.so.0.0.0
/opt/amdgpu-pro/lib/x86_64-linux-gnu/libamfrt64.so.0

still missing the libamfrt64.so.1 so I hacked in a link from that to libamfrt64.so.0 to see if it would fix things. now I get a totally different error
