In testing, the limit seems to be 20000 bytes (which matches RTSPClient::responseBufferSize but increasing them both in sync doesn't work)
I'd rather not hard code a header string in the liveMedia code so is there any nice mechanism to be able to pass additional headers in the RTSP request? I can't see one, and if not, would you be open to patches that implement this?
