vtag.fourcc can no longer be set in mov multiplexer

Description

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!

This may be related to ticket #3351 - I notice the output of the IMX encoding reported was type "m2v1" also instead of the vtag "mx5p" in the command string.

Replying to ortoni:

This may be related to ticket #3351

Could you do the tests requested there?
