Hi, I'm Ivan Ruiz! I'm trying to integrate a webphone on our platform ( http://app.medibaby.net, spanish only :( ). I customized videPhone included on the project, I just add a javascript interface to interact with gateway and copied some code to bring the camera, micros and netstreams up. I am using freeswicht as a SIP server and the siprtmp gateway. The problem is that the video freeze the image, sometimes the video comes back to play but it use to stay freezed. It happens when some frames are too diferent, i don't know how to explain hope you catch the idea.The sound is not affect. Some information about the test Virtual Machine running Ubuntu server 11.10 with Freeswitch and siprtmp gateway inside Local Network Speex16 and h264 codecs Flash 11.5 I've tryied some diferents browsers with diferents computers but I always have this problem. It also happen with videoPhone included on the rtmplite project. I attach a log from command python siprtmp.py -d Thanks for your time !

Hi Ivan,

Sorry about the long delay. Are you still facing the issue.

1) Is the freeze happening on the video played flash player or in SIP?

2) What SIP phone are you using?

There are generally two causes for video freeze on the video played by
Flash Player. (1) a packet was dropped or missed on RTP/UDP and the
siprtmp gateway was never able to recover from the loss. This causes a
freeze on Flash Player's video display. (2) bandwidth is so saturated
on the RTMP/TCP link that Flash Player gives up trying to recover,
disables video, and enables only audio.

To make sure (2) is not the case, try reducing the profile level on
your SIP phone to a lower bandwidth value. If (1) is the problem, then
the SIP phone is not sending intra-frames anymore. It will depend on
what SIP phone you are using to understand the mechanism to report
infra-frame request. Most SIP phones implement the RTCP message to
request fast-update-request, but in siprtmp we didn't implement this.
We only implemented the INFO request for Fast-Intra-Request. May be it
is time to implement the Full-Intra-Request
http://tools.ietf.org/html/rfc2032#page-9 (or its updated RFC).

Let us know the specific problem you are facing.

Regards!
