I have an implementation of an rtsp proxy server based on the live555ProxyServer that ships with the live555 source. When connecting only a couple of viewers to a single proxied stream, things look great. I'm hoping to get a few hundred viewers per stream though. What I'm seeing is that there is a large drop off in quality and kbps as I add more viewers. I see this drop off both with the custom proxy I've written and the stock proxy that ships with the source.
While this is happening, the CPU and memory are only lightly used, and the NIC is not that busy. I'm trying to use this to shield a transcoder that provides an RTSP origin (as well as several other formats). When I run the same test directly against the origin I don't see a drop off in quality like this for viewers less than 50 (and haven't tested that for more than 50 viewers). Hitting the origin directly looks great. Is there perhaps something I should have tuned in the proxy, or could tune with the Linux box this is running on that is causing this drop off? Advice wanted to improve the scaling of single stream => many viewer. The kbps drop off looks like: # of clients , bitrate (kbps) 2 977.688820 3 976.666311 4 936.494160 5 940.096328 6 944.486316 7 955.723431 8 945.044076 9 944.803396 10 930.465372 11 925.247045 12 931.066158 13 713.205068 14 486.331708 15 492.473134 16 485.362249 17 483.711453 18 490.636454 19 485.919289 20 487.862608 21 489.587224 Pete -- The information in this message may be confidential.
