Comment (by ulatekh):

 Thank you for looking into this!

 I applied your patch, and seem to be having different problems now.

 Here's the result of "ffmpeg -i clip.yuv -vcodec copy clip.mov":

 It seems to make a valid archive, but now I can't decode it...here's the
 output from "ffmpeg -i clip.mov -vcodec rawvideo -f yuv4mpegpipe - | head

 Since it seems to want a pixel format, I tried "ffmpeg -i clip.mov -vcodec
 rawvideo -pix_fmt yuv411p -f yuv4mpegpipe - | head -1" and got:

 kdenlive can read the .mov file, but the picture is all white, and it
 still thinks it's progressive.

 If I do the same thing, but with "-vcodec huffyuv" instead of "-vcodec
 copy", I can decode it without a "pix_fmt" argument, but it still comes
 out progressive.

 Thank you once again for looking into this!
