[Live-devel] Live555 performance numbers

[Marathe, Yogesh]

Hello Ross,

Thanks for the prompt response. Assuming I'm not bothered about decoding and rendering part of incoming video (as I can offload that), I want to know if any profiling has been done on just LIVE555's receiving part on any processor ever?

I had observed in one of the experiments with OpenRTSP, if I periodically open multiple threads (using rtspRead()) to receive video streams from different sources, CPU load was going high. The application was just receiving and dropping packets. I want know measures that can be taken in live555 that would enable my system to open maximum possible threads/processes ensuring minimal overhead of receiving and waiting if any.

Regards,
Yogesh.

I want to use live555 for receiving H.264 encoded video streams over IP network through RTP. Is there any information about performance numbers of live555 in terms of CPU cycles or CPU load % when it comes to receiving streams.

It's difficult, if not impossible, to answer questions like this, because the performance of the system depends so much on the particular hardware that you're using.

Generally speaking, though, the performance overhead of LIVE555's RTSP/RTP/RTCP reception/processing code is usually insignificant compared to the cost of receiving/decoding/rendering the incoming video.

E.g., I suggest that you run the VLC media player application, that uses the "LIVE555 Streaming Media" code as its RTSP/RTP/RTCP client, and which can receive and play H.264 video.
