I'm imagining a program that will accept an incoming MPEG-2 transport<br>
stream, demux, add some metadata to the video packets, then remux and<br>
write/stream back out. There will be no decompression or recompression of<br>
the a/v codec data.<br>
<br>
For MPEG-2 video, the data would be added as MPEG-2 user data packets<br>
(appended to each video frame, in frame encoded order). H.264 in MPEG-2 TS<br>
would use SEI RBSP packets. Audio or other packets would be passed through<br>
to the remuxed stream without any changes.<br>
<br>
I can generate the bytes for the actual metadata content, but I'm not sure<br>
how to get this appended within a user data packet or SEI packet to the<br>
video frames while remuxing.<br>
<br>
Does anyone have some ideas, example code or maybe some pointers on where to<br>
look to get started? Thanks!<br>
<br>
