[Live-devel] Received Frames not written.

Hi Ross,

I am using testOnDemandRTSPServer to transmit data and openRTSP to
receive. Sometimes all packets of a certain frame are received (according
to the sequence numbers and size shown as per Reception Stats -
RTPSource.cpp, Reception Stat::noteInComingPacket) but still the frame is
not written into the file (FileSink.cpp - FileSink::addData).  These are
frames in addition to the frames not written due to loss of one or more
constituting packets. Can you tell me what might be happening? Any
pointers will be helpful.

Another doubt is that sometimes in addition to the last frame another
packet (of size 59) is received with same RTP time stamp as that of the
packet comprizing last frame. This is not a part of the data so is not
writeen. Does this packet signal end of file? Which field separates it
from the actual data?

Thanks,
Saumya
