Hi, First of all, english is not my main language, so take care! =) I'm having problems with PJMEDIA performance in my aplication while running it in a OMAP35xx processor (ARM / ~600MHz). The aplication send an RTP stream over the network whenever someone push a button. The stream will be received in many devices(including the one that is generating it) throught Multicast. In the sender side: I've created some (3) streams that should be avaible all the time the program is running, so that the push button -> sound sequence is the fastest possible. Each one send the RTP stream to a different multicast address. In the receiver side: There are at most 3 streams listening to one multicast address each. The sender signals the receiver each time the button is pushed, so I can open/resume the stream processing. But running 6 streams is a bit too much for the processor. When I run the application with gprof enabled, I see get_frame and put_frame as the great consumers of CPU power. I have one conference brigde, so that I can connect wav_players and recorders, so my first solution was to try to disconnect everything from the conference brigde. I tried disconnecting the snd_port also, but no difference in performance with this step. I've searched a bit and found pjmedia_aud_stream_stop and pjmedia_aud_stream_start, but stopping and starting when needed don't make the sound come back. (How) am I supposed to start/stop an pjmedia_aud_stream? Am I missing something? Every thing else is works like a charm! Great library, unfortunately I want to do some unusual things with it. Is there a better way to accomplish the same behaviour that I am missing? Thanks, Fernando -------------- next part -------------- An HTML attachment was scrubbed...
