To whom it will concern: ??? I'm an engineer working in Beijing and I'm writing to seek for help on the two events- play event and record event. In wmme_dev.c of pjmedia_audiodev Line 727, I saw the comment:?? ???? ?/* ???? * Loop while not signalled to quit, wait for event objects to be ???? * signalled by WMME capture and play buffer. ???? */ I would like to know who(which function) sends the event that singlled by WMME capture and play buffer, where can I find it( the specific code line). Thank you very much for your kind consideration! -------------- next part -------------- An HTML attachment was scrubbed...
