Hi,
I agree with Jeremy. You can not perform fast fwd, rewind etc operations
on encoded stream easily. This becomes very easy if you use any
container formats like QT, MP4, Matroska etc. Container formats have
ability to mux various audio video streams with proper synchronization.
You can also perform stream, compression operations at the same time you
can also associate your events using container formats.
Let me know if I can help you more on this or any case you need more
information how container works.

Hi everybody
I would like to know if there is an "out of the box" solution to implement
trickle mode using the TI h.264 codecs (possibly both for the dm6446 and the
dm365). I mean: how can I implement fast forward / fast rewind / frame
skipping / gop skipping in both directions? Or do I have to open the h.264
files and struggle with the h264 headers ?
In general, you can forget about fast rewind--it is prohibitively hard
to do with temporally compressed codecs. And presumably you'll either
have to open the files yourself, or use some third-party API for
working with container formats. (for example, if you're saving h264
to an mp4 container, you could use mp4v2 or ffmpeg)
You could also save raw h264 to disk (raw bytestream), but there
typically isn't timing information present, so it is unsuitable for
playback applications.
Also, is there a "simple" solution to implement file muxing? H.264 +
(say) G.711 + proprietary data ?
For H264 and G711, your best bet is an AVI container. G711 is not a
standard part of the MP4 container format, AFAIK. I'm not sure about
newer containers like matroska.
