[FFmpeg-devel] [PATCH] libavformat/mxfenc: write user comment metadata

[Mark Reid]

Hi,
This patch enables writing of user comment metadata to mxf files. Any
metadata key prefixed with "comment_" will get written as a user comment.
In avid media composer the value will show up in the bin in a column
with the name of the key (minus the "comment_" prefix ofcourse).
The tag values are also written in utf16le to match the same behavour as avid.

example usage:

ffmpeg -y -f lavfi -i "testsrc=size=1920x1080:rate=23.97" -frames:v 50 \
-metadata comment_example=value \
-vcodec dnxhd -pix_fmt yuv422p -vb 36M -f mxf_opatom out.mxf

The tests needed to be update because of the new local tags added to the primer pack.
