ffmpeg 2.7 ignores forced FourCC (-vtag) while multiplexing to AVI

Reported by: LigH Owned by:
Priority: important Component: ffmpeg
Version: git-master Keywords: regression
Cc: Blocked By:
Blocking: Reproduced by developer: yes
Analyzed by developer: no


Summary of the bug:

Multiplexing a raw MPEG4-ASP stream created by xvid_encraw (*.m4v) into an AVI container does not use the FourCC enforced with the parameter -vtag (instead keeps "FMP4").

How to reproduce:

ffmpeg -y -i "*.m4v" -vcodec copy -vtag XVID "*.avi"

More details in the attached report output.

Despite reporting to use the enforced FourCC "XVID", the AVI still contains the FourCC "FMP4" (for both locations in the AVI header).

Is this issue reproducible with current FFmpeg git head?
