[OpenSIPS-Users] About rtpproxy_stream2uac

[microx]

Hi all,

I have one particular application as follows. Suppose client A and client B
had a video call recorded at the rtpproxy a few days ago. Now client B would
like to watch the recorded session from client A to itself. The document of
rtpproxy says that it can play a pre-recorded file to a client and OpenSIPS
provides rtpproxy_stream2uac in the RTPPROXY module. I call start_record()
to make rtpproxy record the video call (which consists of 8 files (2
(caller/callee) x 2 (audio/video) x 2 (rtp/rtcp)). However, I do not realize
how to use  rtpproxy_stream2uac() to make client B can watch what client A
sent to him/her a few days ago. I find very few threads on the usage of
rtpproxy_stream2uac in this forum. My questions are specifically listed
below.

1. The rtpproxy play the file in what format to the client? Do I need to
merge .rtp .rtcp files into one file in the format like mp4? Since
rtpproxy_stream2uac only provides a file name, I don't know how client B can
receive audio and video streams.

2. Client B wants to watch the recorded video call and thus no so-called
callee in such a case. From rtpproxy_stream2uac(), it seems that one caller
and one callee are required?

Anyone has similar experience on this issue? Any comment is appreciated. 

PS. The versions of OpenSIPS and rtpproxy I used are branch 9585 and 1.2.1,
respectively.

Best regards,
Chen-Che
