[Live-devel] TCP streaming problem with LIVE55

[Ross Finlayson]

First, if you have access to the IP camera - and are able to completely control what runs on it - then why are you using a proxy server at all?  Why not modify the H.264 stream (to add SEI NAL units) as it comes from the camera’s H.264 *encoder*, and just run a single RTSP server (not a proxy server) to stream the modified stream?

If instead you are running - inside your IP camera - “encoder” + “built-in RTSP server” + “your modified proxy server (which manipulates (presumably with lots of data copying) the H.264 NAL unit stream)”, then perhaps you are becoming CPU bound?

What is errno 11 on your system? (Run “man errno”?)

In any case, when streaming-over-TCP fails (as it did for you), it means that the data rate of the stream exceeds the capacity of your TCP connection.  In this case, that might be because your IP camera’s CPU (and/or memory subsystem) is becoming overloaded (from all of the extra stuff you’re running on it, with all of the extra data copying), causing its effective TCP data rate to drop.

In any case, why are you streaming over TCP?  If you haven’t already done so, please read:
