I am trying to solve a crash in my code that shows up at the line indicated in MyultiFramedRTPSource.cpp from the 2013.03.07 livee555 code. I had this same issue with the 2012.02.29, so I updated. When I inspected the packet before the update, it was always the fBuf value that was 0xddddddd but this time absolutely everything looks valid.
class ReorderingPacketBuffer {
public:
ReorderingPacketBuffer(BufferedPacketFactory* packetFactory);
virtual ~ReorderingPacketBuffer();
void reset();
BufferedPacket* getFreePacket(MultiFramedRTPSource* ourSource);
Boolean storePacket(BufferedPacket* bPacket);
BufferedPacket* getNextCompletedPacket(Boolean& packetLossPreceded);
void releaseUsedPacket(BufferedPacket* packet);
void freePacket(BufferedPacket* packet) {
if (packet != fSavedPacket) {
delete packet; <<<-------------Access violation here
} else {
fSavedPacketFree = True;
}
}
The 0xdddddddd is a magic value placed in pointer locations by the debug
runtime to signal that the memory the pointer points to has already been
released. To make it easier to find.
The only thing I can see is that the packet size is 20000 but the memory at
that location is only 23 bytes and the rest is the cdcdcd... pattern which is
"Clean memory" it means it is newly initialized and so even that looks ok.
Any suggestions on how to track this down? This was after a few minutes of
streaming video.
