Hi Deepika, I've got the basic idea of it working now. For MPEG-2 Video it is relatively simple as you can just append the user data structure to the end of the frame data. It looks like: 0x000001b2 [user data] 0x000001 For H.264 you must construct a NAL type 6 containing a SEI message: 0x00000106 [SEI message starting with payload type] 0x00 [payload size] 0x80 This gets inserted into the packet after any other SEI messages but before the first video slice, so you have to parse the NALs in the frame data to find the insertion point. Hope this helps, Jason -- View this message in context: http://libav-users.943685.n4.nabble.com/Add-MPEG-2-user-data-or-H-264-SEI-metadata-while-remuxing-tp4530217p4606610.html Sent from the libav-users mailing list archive at Nabble.com. _______________________________________________ Libav-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/libav-user
