Hi, I'm building an application to support RTSP over HTTP using live555, and I ran into a situation that the CPU usage (1 core is completely used) is high (25% or above).
Here are the information: 1. windows 7 x64, network 1Gbps, CPU i5 4 cores 2.8GHz, 8G RAM 2. building application with VS2010, application is x64, and I assign the live555 thread to a specific core via windows API. Therefore I can observe which thread is eating up the cpu usage. 3. Concurrent session: 64. (all different sources) 4. H264 video source received from my own camera. 5. I subclassed FramedSource to implement method doGetNextFrame and method afterGetting, and let the delay be 100us when try to call scheduleDelayedTask. When there is a frame available, I copy the bitstream into fTo, assign the fFrameSize according to fMaxSize, and then calculate the fNumTruncatedBytes. If there are remaining bitstream of a frame, I would store it for next doGetNextFrame call, so that all frames are not truncated. Is this correct or related to my current situation? 6. I also subclassed OnDemandServerMediaSubsession to implement my own method checkForAuxSDPLine. 7. If I reduce the concurrent session count to 32, the cpu usage is the same as 64, but the thread of live555 can not handle more than 64 sessions. If more information is needed, please let me know, thank you. I'm kinda new to live555 and the mailing list, forgive my poor presentation skill in Engilish.
