Hey there,
i am trying to write metadata to an mxf file.
ffmpeg.exe -i Z:\hide\MXF_files\A019C046.mxf -an -f mxf_opatom -b:v 36M
-metadata comment_x=y out.mxf
Before ffmpeg version 2.8.2 this line worked as expected.
A ffmpeg -i out.mxf shows
comment_x : y
But in version 2.8.2 that changed.
In the changelog I find
- avformat/mxfenc: Only store user comment related tags when needed
So it seems there is a new muxer option for mxf_opatom
store_user_comments bool
But no matter what I try, there is no user comment in the metadata after
rendering.
ffmpeg.exe -i Z:\hide\MXF_files\A019C046.mxf -an -f mxf_opatom
-store_user_comments 1 -b:v 36M metadata comment_x=y out.mxf
Am I doing something wrong?
Can anyone shed some light?
Thank you!
Best,
Jules
