I tried to trivially add qsv/mediacodec decode to cinelerra-gg, but
discovered that I can't use it like vaapi/vdpau/cuda because (?)
qsv/mediacodec not listed in
ffmpeg/libavcodec/hwconfig.h
and (for h264) in
ffmpeg/libavcodec/h264dec.c
so on decoding I get (in termux, cingg compiled with system ffmpeg)
Decoder h264 does not support device type mediacodec.
HW device init failed, using SW decode.

You use a supported Intel (i)gpu?
