Comment (by heleppkes):

 The format by definition requires a FourCC, if no FourCC exists, then you
 cannot store this format in V_UNCOMPRESSED. What you expect doesn't match
 the reality.

 Like you said, it should produce working files, and for files to be
 working, V_UNCOMPRESSED requires a *VALID* FourCC, not something
 arbitrarily invented based on the short name ffmpeg assigned to it.
