[Ffmpeg-devel] [BUG/FEATURE][PATCH] dv encoder pixel format

When trying to convert some video to dv in avi this occurs:

./ffmpeg -i ~/samples/Hackclip.avi -vcodec dvvideo  -acodec pcm_s16le 
Stream #0.0, 29.97 fps(r): Video: mpeg4, yuv420p, 720x480
video:0kB audio:644kB global headers:0kB muxing overhead 1.863588%

No video and a corrupt file, while adding -pix_fmt yuv411p gives this:

./ffmpeg -i ~/samples/Hackclip.avi -vcodec dvvideo -pix_fmt yuv411p 
-acodec pcm_s16le  test.avi
video:18633kB audio:644kB global headers:0kB muxing overhead 0.081544%

A playable file, so doesn't dv support yuv420p? And if that is the case
is it ok to apply this path ?
I know nothing about dv but I think it would be wise check the pixel
format somewhere and aid the user.

Oh, a user reported happily that with -pix_fmt yuv411p added Premiere
was able to import the files.

"incorrect information" is an oxymoron. Information is, by definition, factual, correct.
