Hi,
I'm streaming videos from an RTSP on demand server with LiveMedia.
I wrote my own "FramedSource" subclass and my own
"OnDemandServerMediaSubsession" subclass in order to stream frames
acquired from my live source, rather than from a file.
This solution streams correctly, but when I close my client and it sends
a TEARDOWN message to the server, the server crashes with SIGABRT and a
message of "rtspServer: munmap_chunk(): invalid pointer: 0x08193dc0 ***".
Further investigation leads me to locate the offending instruction in
MediaSink.cpp OutPacketBuffer::~OutPacketBuffer() method. In particular,
the signal is generated when I try to execute the instruction delete[]
fBuf;
The method is called respectively by ~H263plusVideoRTPSink destroyer
function, called by MediaLookupTable::remove method.
Why does it happen? the only interaction I have with
H263plusVideoRTPSink is when i create it in createNewRTPSink, defined in
my OnDemandServerMediaSubsession subclass, like this:
RTPSink* EncH263plusVideoFileServerMediaSubsession::
createNewRTPSink(Groupsock* rtpGroupsock,
unsigned char rtpPayloadTypeIfDynamic,
FramedSource* inputSource) {
return H263plusVideoRTPSink::createNew(envir(), rtpGroupsock,
rtpPayloadTypeIfDynamic);
}
Is it the correct way to create the sink? And what could cause the
corrupt or double-delete in ~OutPacketBuffer?
Thanks in advance,
Best Regards,
Cristiano.
