Re: FFmpeg qsv_av1 – Intel Community

Sure:

– AMD Ryzen Threadripper 2920X 12-Core Processor

– Acer Predator BiFrost Intel Arc A770 OC 16GB GDDR6

– Ubuntu 20.04.6 LTS

– Kernel 6.5.5-060505-generic

 

I compiled all the latest master branches as of yesterday of oneVPL, oneVPL-intel-gpu, MediaSDK, libva, libva-utils, GmmLib, Intel(R) Media Driver for VAAPI, and enabled –libvpl configuring latest FFmpeg 6.0…

I couldn’t find the strictly required libs for transcoding AV1 on the A770 with FFmpeg, so maybe I installed something that is not strictly required?

 

I set there env variables:

export LIBVA_DRIVERS_PATH=/usr/local/lib/x86_64-linux-gnu/dri/
export LIBVA_DRIVER_NAME=iHD

 

Sample cmd:

ffmpeg -hwaccel qsv -qsv_device /dev/dri/renderD128 -c:v h264_qsv -i input.ts -c:v av1_qsv -preset slow -b:v 512k -bufsize 512k -maxrate 1024k -c:a libopus -vbr off -ac 2 -b:a 48k -f Matroska output.mkv

 

Thank you.
