Hi, Is it ok if i create two pjmedia streams(str1, str2) in the main thread, where the 2 Media Endpoints instantiate there own two internal IOQueues and start one poll worker thread each to poll the IOQueue. Now if i try to access these media streams from another thread, which calls pjmedia_port_get_frame(str1) and pjmedia_port_put_frame(str2) to get and put frames from the above created streams, would it cause any problem? Does creating a poll worker thread has any issues, if i access the streams from a totally different thread? Thanks Manjeet -------------- next part -------------- An HTML attachment was scrubbed...
