<br><font size=3 face="sans-serif"> I have been trying to stream
H264 annexB bytestream with livemedia, and have made little progress these
days. </font>
<br><font size=3 face="sans-serif"> My own xH264VideoStreamFramer(subclass
of H264VideoStreamFramer) and H264VideoFileServerMediaSubsession have been
done.<br>
<br>
To check my classes, I modified live555MediaServer, and use it
as the server while openRTSP as client for test.<br>
<br>
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.<br>
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.<br>
<br>
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.</font>
<br>
<br><font size=3 face="sans-serif">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.</font>

<br><font size=3 face="sans-serif"> I checked the "fOctetCount"
member of class "RTPSink", and found that when "MultiFramedRTPSink"
call its "onSourceClosure()" function,<br>
live555MediaServer already sent 70574 Bytes to the client(openRTSP).
But on the client, the data received is incomplete and variational.<br>
<br>
What might caused this problem? <br>
<br>
Any help will be appreciated!<br>
