Hi All, First I know that the the android support of Pjsip only supports Audio. * Audio works fine. * I have enabled the video support was able to get the video call running successfully with some hacks * The major issue I noted was for the video rendering The issue is as follows * The video call starts with resolution of 720x480 * After the sip media negotiation and when the frame is decode, I get a decoding format change indication the new resolution is 640x480 * At this instant in the rendering callback in file vid_port.c , in function client_port_event_cb(), pjmedia_vid_port_stop(vp) is called. * In pjmedia_vid_port_stop(vp) function, we stop the clock pjmedia_clock_stop(vp->clock); * Inside pjmedia_clock_stop(vp->clock) , in file clock_thread.c * pj_thread_join(clock->thread) is called, this function never returns, its just hangs due to which the pjmedia_vid_port_start() for rending is never called * Hence the video renedring thread never starts. As a hack/work around I did not call the pjmedia_clock_stop(vp) in pjmedia_vid_port_stop(vp) function, by doing this everything works fine. I am not sure whats the issue here and why pj_thread_join((clock->thread) is stuck I also noted that some concurrency issue is fixed and all this code was added in ticket http://trac.pjsip.org/repos/ticket/1394 I really appreciate if some could help me to fix this or analyze if for android anything needs to be done.
