Hi all!

I would like to achieve PJSIP to work in some sort of a hybrid mode. SIP-wise it will act as a full SIP client (registers, make and receives video with audio calls). Instead of using a local camera device it would receive an RTP input from a local device.

For example, when it gets an incoming call from a remote SIP client, it will be able to answer the call through SIP. PJSIP will not use a video froma local camera to send the video. Rather, it will simply proxy an RTP coming from a local device to a remote SIP client. And the local device will be getting a video coming from a remote SIP client. Hence, it is simply proxying RTP back and forth. The same applies to outgoing calls.

Graphically, it can be represented as on the diagram below. My question is what would be the best approach to accomplish this with PJSIP? Ideally, PJSUA2 but I accept ideas at any API level.

Regards,
Zarko

Zarko,

in the similar scenario we've ended up with creating dedicated pjmedia_vid_dev_factory which in turn creates render device baked by a gstreamer pipeline.

Thanks Andrei for the info. How difficult was to accomplish all this?

maybe you could consider use pjsip-ua api (pjsip inv and pjsip regc)and a
simple socket rtp proxy.
