I added the line for increasing the receive buffer, but it didn't make the
output images any better. Thanks for the suggestion. Anything else I should try
or investigate?
Below is the continueAfterSETUP() after the addition of the new line.
void continueAfterSETUP(RTSPClient* rtspClient, int resultCode, char*
resultString) {
do {
UsageEnvironment& env = rtspClient->envir(); // alias
StreamClientState& scs = ((ourRTSPClient*)rtspClient)->scs; // alias
scs.subsession->sink = DummySink::createNew(env, *scs.subsession,
rtspClient->url());
env << *rtspClient << "Created a data sink for the \"" << *scs.subsession
<< "\" subsession\n";
scs.subsession->miscPtr = rtspClient;
increaseReceiveBufferTo(env,
scs.subsession->rtpSource()->RTPgs()->socketNum(), 2000000);
FramedSource *src = scs.subsession->readSource();
scs.subsession->sink->startPlaying(*src, subsessionAfterPlaying,
scs.subsession);
if (scs.subsession->rtcpInstance() != NULL) {
scs.subsession->rtcpInstance()->setByeHandler(subsessionByeHandler,
scs.subsession);
}
} while (0);
delete[] resultString;
setupNextSubsession(rtspClient);
}

Subject: Re: [Live-devel] testRTSPClient and MJPEG decoding
I'm able to view the RTSP stream in VLC
OK. One thing that VLC is doing that "testRTSPClient" is not is setting an
extremely large receive buffer (in the operating system) for the RTP socket.
This may be necessary for you, because you're trying to receive a stream that
uses such a ridiculously inefficient codec (i.e., JPEG).
So, try the following:
Add
#include <GroupsockHelper.hh>
to your application, and add the line
increaseReceiveBufferTo(env, scs.subsession->rtpSource()->RTPgs()->socketNum(),
2000000);
to your "continueAfterSETUP()" function.
