 Previous versions (e.g. v 1.1) of ffmpeg allowed the 'fourcc' to be set
 for IMX using "-vtag mx3p". This sets the "type" field in the stsd atom in
 the mov.

 v 2.1 ffmpeg and above does not set this information but does not complain
 about the "-vtag mx3p" option:

 command:
 ffmpeg -i work.m2v -i stereo.wav -vcodec copy -acodec copy -vtag mx3p -r
 25 imx21.mov

 stsd atom reports type = m2v1 instead of mx3p.

 Input files are correct types for this output format, and the same
 commands and files with v1.1 ffmpeg work correctly

 I also tried video file alone:
 ffmpeg -i work.m2v -vtag mx3p -r25 imx.mov

 with same result

 As ever, thank you ffmpeg developers!
