More like incomplete code that does not yet know how to get custom format
... so far as name says it only adds 10bit 4:2:0  encoding, not 4:2:2
subsampling.

can you test other vaapi/qsv profiles too?


also with test picture actually containing more than 8bit values? ;)
(probably made up something in GIMP 2.10, save as tiff/EXR, import in
cingg, set format to rgba-float, rendrer ..... hm, may be use YUView to see
pixel values independently of cinelerra's decoding abilities? a bit of
adventure, but should provide some proof about encoding)
