Comment (by ulatekh):

 Speaking as someone that doesn't know enough about video codecs etc. to
 develop ffmpeg...I would prefer that ffmpeg refuse to produce something
 that doesn't meet specs, and if asked to do so, ffmpeg should report an
 error and then provide some hints as to what would meet specs.

 For example, after chatting with others on the #ffmpeg IRC channel, I
 eventually found three pixel formats that worked with raw video in a .mov
 container -- rgb24, uyvy422, and rgb565.  But ffmpeg would generate files
 with other pixel formats, and then those files couldn't be decoded.  This
 is unhelpful and unproductive.  I would prefer that ffmpeg be stricter
 with the user's request, and in the above example, list what pixel formats
 would have been allowed with raw video in a .mov container.
