Greetings all.
First post, so I'll only waste a little bandwidth saying "AWESOME LIBRARY!" and
move to my issue.
I'm trying to incorporate the MPEG1or2VideoRTPSource into my application. My
application needs to poke a web service to start the RTP stream, so RTSP isn't
appropriate. I just want to listen to the UDP port and capture the stream as it
comes in. I can do this in Java by just opening up a DatagramSocket, decoding
the RTP packets as they stream in, but I'd like to use this library and other
features of it.
I create the BasicUsageEnvironment and TaskScheduler as:
TaskScheduler *bts = BasicTaskScheduler::createNew();
BasicUsageEnvironment *bue = BasicUsageEnvironment::createNew(*bts);
Then I create a Groupsock to listen on my expected UDP port:
const Port rtpPort(8898);
struct in_addr inAddress;
inAddress.s_addr = our_inet_addr("0.0.0.0");
Groupsock gs(*bue, inAddress, rtpPort, 1);
And thirdly I create the FileSink and start the playing:
sink = FileSink::createNew(*bue, "stdout");
source = MPEG1or2VideoRTPSource::createNew(*bue, &gs);
sink->startPlaying(*rtp_stream->source, mySessionEndCallback, NULL);
Finally - Start the eventLoop:
bts->doEventLoop();
At this point my application exits with this error:
BasicTaskScheduler::SingleStep(): select() fails: Bad file descriptor
I'm sure I'm not the first to hit this issue, but I've yet to find a reason.
If I create a NEW TaskScheduler that isn't bound to the BasicUsageEnvironment
and then call "doEventLoop()" -- the process continues, but packets never
stream. Am I missing something thickheaded?
tia, and keep up the good work!
Ken
