Add Hardware VAAPI encoding support

[cdgriffith]

This is more difficult as basic things like scaling are done differently with vaapi. Opening separate issue to track this and possible beta tries with this version.

Any update on VAAPI support?

Have not spent any effort on that yet myself. Always looking for other contributors!

hi, i have a IGPU AMD 4800u. If i want encode with vaapi and HEVC i use:

ffmpeg -hwaccel vaapi -hwaccel_device /dev/dri/renderD128 -hwaccel_output_format vaapi -i input.mkv -vf 'scale_vaapi=w=1920:h=800' -c:v hevc_vaapi -rc_mode CQP -qp 26 -c:a copy -strict unofficial output.mkv

i think for AMD a vaapi profile works so it's a good idea to add in the list.

Best regards.

+1 to see that coming to live. But I'm using ffmpeg -vaapi_device /dev/dri/renderD128 -i INPUT -c:v hevc_vaapi -b:v 3000k -c:a aac -b:a 160k -c:s copy -map 0:v:0 -map 0:a:0 -vf format='nv12|vaapi,hwupload' OUTPUT with my AMD Ryzen 5 PRO 3400G / Vega 11, which should do the same as the example above.

Finally added in 5.5.0! For HEVC, AVC, VP9 and MPEG2 https://github.com/cdgriffith/FastFlix/releases/tag/5.5.0
