I wasn't thinking about using existing softphones.
I'm not sure how to integrate the softphones existing, as I said, I
don't currently have any video softphones.
I also believe using a complete open source software video stack would
better than any existing video phones....
But, I think it should work using existing softphones too..
I want to leverage what is existing in terms of video transcoding,
packetization, decoding, etc.
Look at all the great things VLC does already in terms of streaming....
RTP/UDP, RTSP, Raw UDP, (RTP or raw) Multicast, HTTP,MMSH
Yes, you are correct to point out the issues with NAT. I didn't address these.
That is sort of my question.
Can we utilize the VLC RTP/UDP to work like a softphone.
Could we use it as it is...or can we write some kungfoo to read the
packetized stream already provided by VLC and push it into freeswitch?
Again, I need to spend more time with the freeswitch code....to
understand the underlying RTP handling.
