Re: [ooh323c-devel] Setting different codec capabilities for the same peer (channel)

[Aleksandar Sutic]

Avin,         Thanks again for you answers. They just verified behaivor I was affraid of :-) . However, I easily found workaroud for this. The problem was that I didn't like too may threads running on my machine. Now only the first startReceiveChannel() callback really creates a thread, while the other just add sockets that already running thread should monitor. Since every audio codec has its own OORTPSOCKET structure (see media example), I can smoothly extract the information about it in receive and transmit threads.     Regards,        Aleksandar Avin Patel wrote: Hi Aleksandar, What exactly do you mean under "on logical channel established"? There is Search for "OO_LOGICALCHAN_ESTABLISHED" & add a callback function of logical channel established. Also, when I register several capabilities for the same endpoint, it turns out that before a call is established, receive channel callbacks (caller party side) are triggered for every registered capability. This was strange for me since I was expecting that only negotiated codec's channel callback would be triggered. Any remarks on this? This is ok, till the logical channel is established. My media library mimics the obj-sys media and the logic is completely the same (though media is compiled as static library since uCLinux does not support shared libraries). In the attached file, I register some codecs at line 331: /* Add audio capabilities */ ooH323EpAddG711Capability(OO_G711ALAW64K, 20, 160, OORXANDTX, &spcEpStartReceiveChannel, &spcEpStartTransmitChannel, &spcEpStopReceiveChannel, &spcEpStopTransmitChannel); ooH323EpAddG711Capability(OO_G711ULAW64K, 20, 160, OORXANDTX, &spcEpStartReceiveChannel, &spcEpStartTransmitChannel, &spcEpStopReceiveChannel, &spcEpStopTransmitChannel); ooH323EpAddG7231Capability(OO_G7231, 30, 24, TRUE, OORXANDTX, &spcEpStartReceiveChannel, &spcEpStartTransmitChannel, &spcEpStopReceiveChannel, &spcEpStopTransmitChannel); ooH323EpAddG729Capability(OO_G729, 20, 20, OORXANDTX, &spcEpStartReceiveChannel, &spcEpStartTransmitChannel, &spcEpStopReceiveChannel, &spcEpStopTransmitChannel); Is it legal to register several audio codecs at the same time? Yes, you can. But only one channel will be used for communication, once call is established. When I do this, caller party triggers spcEpStartReceiveChannel() four times, but after the voice streaming is established, only one transmit channel is started. That is correct behaviour. End Point should be ready to communicate on all proposed channels. While only channel will be used for communications. Once channel is established, all other channel will be closed.
