There is a mod_h26x in tree that provides a passthru codec
for h261 h263 and h264.

The only thing we have implemented so far with video is the
"echo" application that will also echo video in a separate thread.

The core code for that can be found in switch_ivr_async.c at 
about line 63 and above.

The next goal was probably to add another thread to bridged calls
to pass video back and forth the same way the audio is done.

>From there we needed a strategy on how to read and write video files.
Asterisk uses 2 difft files but i would prefer to be able to read/write
a standard multi-media format like mp4 etc.

I think a core abstraction like we did for audio files may be unnecessary
and it would probably be better to make a loadable module that implements
functions to read and write the video files via the application interface.

Hi -

Could someone write a few words on the state of video calling in FS?  
The no media
mode works fine, but I'm interested in being able to take do things
 with 
the media streams.

What I've done so far:
- create an H.264 passthrough codec, derived from the G.729 one;
- tamper with the video codec negotiation code to get that bit to work.

What I'm not sure of is how much else is implemented or not and, before
 
I hide in a dark
corner with a large pot of coffee to work through what's done and
 what's 
not, I figured I
might ask..

Cheers --

Dave
