[FFmpeg-user] question regarding store_user_comments

Wed Jan 25 18:02:06 EET 2017

Tested it with the latest git snapshot.
Does not make any difference.
If nobody has an idea why it is not working I`ll try bmxtools next.

Thank you all
Best,
Jules

Probably unrelated, but using
 -t xx
 or
 -shortest
on creating MpegII (XDcam) Op1A files will make avid bitch about something 
with 'mob' (I forgot the exact details, but can create testlines if you 
like..)
