Comment (by eero-t):


 Scaling and format conversions seem to be working now, except for
 "uyvy422" which has been segfaulting for several months now:


 Only scaling and "nv12" format works, for all other formats I get:
 $ ffmpeg -hwaccel qsv -qsv_device /dev/dri/renderD128 -c:v hevc_qsv -i
 1920x1080_60_yuv420p.h265 -vf
 scale_qsv=w=1920:h=540,hwdownload,format=yuv420p -f null -
 Input #0, hevc, from '1920x1080_60_yuv420p.h265':
   Duration: N/A, bitrate: N/A
     Stream #0:0: Video: hevc (Main), yuv420p(tv), 1920x1080, 60 fps, 60
 tbr, 1200k tbn, 60 tbc
 Stream mapping:
   Stream #0:0 -> #0:0 (hevc (hevc_qsv) -> wrapped_avframe (native))
