Dear Colin, I'm using RTSP over HTTP, and by looking at the packets dumped by wireshark. I saw something like this:
RTSP/1.0 200 OK CSeq: 4 Date: Thu, Jun 27 2013 05:29:16 GMT Transport: RTP/AVP/TCP;unicast;destination=<destination address>;source=<source address>;interleaved=0-1 Session: <session id> Hence I think the interleaved mode is used, and the source generated by my camera contains only single video stream (without audio stream). After checking the patch submitted by you in April, I believed that the latest version of live555 contained that patch already. I did try the latest version of live555 (live.2013.07.03.tar.gz), but the result is still the same. Thank your for your kindly response! 2013/7/12 Colin Caughie <ccaug...@openeye.net> > Are you a) using interleaved mode and b) not processing one or more of the > streams in the session (e.g. throwing away an audio stream)?**** > > ** ** > > If so, it could be the issue I reported here: > http://lists.live555.com/pipermail/live-devel/2013-April/016796.html**** > > ** ** > > *From:* live-devel-boun...@ns.live555.com [mailto: > live-devel-boun...@ns.live555.com] *On Behalf Of *West Chen > *Sent:* Wednesday, July 10, 2013 7:33 PM > > *To:* LIVE555 Streaming Media - development & use > *Subject:* Re: [Live-devel] CPU usage is high when there are 64 > concurrentsessions.**** > > ** ** > > Dear Ross,**** > > ** ** > > I do modify the macro FD_SETSIZE=1024, but the situation is still the same. > **** > > Or is there any other limitation that might help?**** > > ** ** > > Thank you for your quick reply!**** > > ** ** > > 2013/7/11 Ross Finlayson <finlay...@live555.com>**** > > I presume - from your question - that you see high CPU usage *only* when > you have a large number of concurrent client connections, but not if you > have a small number of concurrent client connections.**** > > ** ** > > If this is the case, then the problem is almost certainly caused by you > running into an OS-imposed limit on the number of open files (sockets) that > can be used by a single process.
