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

Description

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).
