 Replying to [comment:6 cehoyos]:
 > Then why did you test with a different command line?
 because when I tried with
 {{{
 ffmpeg -vaapi_device /dev/dri/renderD128 -hwaccel vaapi -i
 aspect_ratio_change_cut.ts -y -g 30 -vf 'format=nv12,hwupload' -c:v
 h264_vaapi -qp 20 -sn out.ts
 }}}
 failed with error message
 {{{
 [AVHWFramesContext @ 0x556ae298be00] Failed to sync surface 0x4: 23
 (internal decoding error).
 [mpeg2video @ 0x556ae2707440] Failed to transfer data to output frame: -5.
 }}}
