Hi Dmitry!
Hello!
So, our original conversation is here: http://lists.digium.com/pipermail/asterisk-video/2012-April/003621.html As I said in our previous conversation, we don't currently have plans to implement a re-transmission of a new source's I-Frame, or delay switching of the video source until an I-Frame from the new source arrives. I wouldn't characterize that as a "refusal". I was simply informing you of the actual state of affairs: we do not have plans at this time to implement this feature.
Well, from my point of view this is refusal , just because this is real result :-)
That being said, as I mentioned in our discussion, Asterisk should have some built in mechanisms currently to help alleviate this situation. It should send a SIP INFO request when a video source changes notifying the client that it is the new video source. The client can then transmit a new I-Frame, which alleviates the need for Asterisk to delay switching of the video source (or otherwise manipulate the video stream in some fashion itself). As I asked in the e-mail:
Really, I never read this mail...
"1. What clients are you using? Do they support RFC 5168 (XML Schema for Media Control)?
We did tests with jitsi, just because it is mentioned as tested in asterisk wiki.
( https://wiki.asterisk.org/wiki/display/AST/ConfBridge+10 ) I don't know does it support rfc5168 :-(
2. If you get a SIP trace or a packet capture, do you see Asterisk sending the SIP INFO messages when a video update occurs?"
Don't know too.
Since I never got a concrete answer to those questions, I'll ask again: Do your clients support RFC 5168? If not, do you have significant problems with clients that do support RFC 5168?
Could you point me to client with such support? I see no info about this on link above. Thank you!
