Build with patches is OK.

render with DPX.dpx:

Render::render_single: Session finished.
** rendered 4726 frames in 41.222 secs, 114.648 fps

The resulting file is 11 MB, but it won't open in mpv or ffplay. I think it only renders the first frame.


Render with mpeg2_hq.mpeg (4:2:2): everything is ok. File is OK.

Gif: I'm not quite sure what to do. A render with gif.gif is OK.

It's one of those days when I'm feeling confused; I don't think I can be of any help.
