Hello,

I have been trying to stream H264 annexB bytestream with
livemedia, and have made little progress these days.
My own xH264VideoStreamFramer(subclass of H264VideoStreamFramer)
and H264VideoFileServerMediaSubsession have been done.
To check my classes, I modified live555MediaServer, and use it as
the server while openRTSP as client for test.
But when running, the bytestream cannot be transported
completely. Only the first few datas can be received. What puzzles
me more is that the amount of datas received is variational.
The size of H264 annexB bytestream file on the server is 70574
Bytes, sometimes the receiver can only receive the first 48KB, or
sometimes 68KB. 70574B can rarely been received completely.
I also compare the data received on client with the bytestream
file on the serever, and found that these data are just the first
part of the bytestream.
I have been working on a H.264 annex G video stream framer. For me,
the last access unit is not being transmitted, and I attribute this to
my file parsing code, which by nature of the live library does not
recognize the end of the file properly and therefore does not reach/
mark the end of the last access unit.

I checked the "fOctetCount" member of class "RTPSink", and found
that when "MultiFramedRTPSink" call its "onSourceClosure()" function,
live555MediaServer already sent 70574 Bytes to the
client(openRTSP). But on the client, the data received is incomplete
and variational.
What might caused this problem?
Any help will be appreciated!
Best Regards
Felix
