PJMEDIA conference bridge - direct port?

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

I was wondering if there is a means by which I can throw PCM frames 
straight into a conference bridge.  Is this possible?  If so, which 
type of port should I use for this purpose?  I have tried various 
combinations of the memory capture / playback ports, but without 
success;  when I read from the bridge master port, all I get are 
zeroed frames.

The reason I want to do this is that I am selectively reading RTP 
frames from a packet capture, and just want to mix them together 
according to a certain scheme.  The conference bridge is perfect for 
this, but I don't want to write out a WAV file first and then read it 
back in.  That's wasteful and also causes length/timing issues.

Is there a kind of port that I can pjmedia_conf_add_port() and which, 
when I put frames into it (e.g. pjmedia_port_put_frame()), will result 
in those frames being contemporaneously mixed in the bridge?

Thank you!
