[Live-devel] problem streaming to vlc

[xavier]

Thank you again for your response, Ross


I've updated the library to the latest version and now use the "testMPEG1or2VideoStreamer"
as a base code and now the StreamParser does not complain at all. Although vlc now
receives the sdp
descriptor with the correct rtp session parameters (before following Ross's advice, it
wouldn't even communicate with the server), its decoder outputs a <<TaskInterrupt>> all the
time.
I don't know if my server is not streaming the rtp session at all or if the
information from my AVFrame gets messed up in the parsing process. Maybe the
fPresentationTime that I acquire from the system lead to an error?

this is a little bunch of the code using liveMedia:

static struct timezone quin;
static AVFrame *picture;
static int size;//en bytes

void RPVRFramedSource::doGetNextFrame() {
fFrameSize = size;
if (fFrameSize > fMaxSize)
{
fNumTruncatedBytes = fFrameSize - fMaxSize;
fFrameSize = fMaxSize;
}
memmove(fTo, picture->data[0], fFrameSize);
gettimeofday(&fPresentationTime, &quin);

nextTask()
= envir().taskScheduler().scheduleDelayedTask(0, (TaskFunc*)afterGetting,
this);
}
this is the modified play() method of the main code (I've left the rest untouched).

RTPSink* videoSink;
FramedSource* videoSource;
RTPSink* videoSink;

void play() {
RPVRFramedSource* videoES=RPVRFramedSource::createNew(*env);
// Create a framer for the Elementary Stream:

videoSource
= MPEG1or2VideoStreamFramer::createNew(*env, videoES, iFramesOnly);
// Finally, start playing the sink.
*env << "Beginning to read ...\n";
videoSink->startPlaying(*videoES, afterPlaying, videoSink);
}
then, in the main loop, the session is added to the server:

sms->addSubsession(PassiveServerMediaSubsession::createNew(*videoSink, videoRTCP));
rtspServer->addServerMediaSession(sms);

Thanks for your patience,
xavier
