Comment (by micolous):

 I figured out what was wrong with my patch: I didn't implement the output
 format converter in `ff_sws_init_output_funcs`. I've uploaded a new
 version of the patch (v2), so this now appears to round-trip correctly
 with an `ay10be` raw frame:

 {{{
 ffmpeg -i /tmp/atem-colourbars5.expanded.png -f rawvideo -pix_fmt ay10be
 -colorspace bt709 /tmp/atem-colourbars5.redux
 ffmpeg -f rawvideo -pixel_format ay10be -colorspace bt709 -video_size
 1920x1080 -i /tmp/atem-colourbars5.redux -pix_fmt rgba /tmp/atem-
 colourbars-redux.'%03d'.png
 }}}

 `ay10le` also seems to round-trip correctly, and generates a different
 file.

 Images with alpha channels appear to also work correctly.
