[Ffmpeg-devel] MPEG2-TS User Defined Data

Sorry about that.  I'm looking at ISO 13818-1.  I didn't realize that PID 0x66 was just an
in-house method of identifying user defined data.  Basically, my problem isn't the 
extraction of the data, its the synchronization of the data with the video stream.With
JMF, I'm currently stuck using two source streams (one for video, other for meta-data),
which is completely throwing off any semblance of timing between the meta-data and the 

Anyways,I just wanted to know if I had to implement my own modified demux, and you already
answered that question.

Which standard are you looking at?  ISO 13818-1 (MPEG PS/TS) doesn't give PID
0x66 any special meaning, and DVB uses it for EIT.  Whatever you're looking
for, the ffmpeg demuxer doesn't give access to non-AV data, although a hack
doesn't seem too difficult.
