Hi Ross,

Thanks for your quickly replay.

We have a rtsp server on embedded system, rtsp server will stream out H264+ulaw 
streaming.
Now, we face a problem. There is a vlc client to connect our rtsp server.
If the audio is
A. under 8K, 16bit, mono ulaw(encode from PCM), we set fDurationInMicroseconds 
to be 64000. Audio is good.
B. under 16K, 16bit, stereo ulaw(encode from PCM), we set 
fDurationInMicroseconds to be 16000. Audio is vibration.

For 16K, 16bit, stereo,
we try to record PCM file and play PCM on vlc, PCM is good.
we try to record PCM, encode ulaw to file and play ulaw file on audacity, ulaw 
are good.

Under this situation, do you have any suggestion? Thanks for your kindly 
sharing.

regards, eric, 12/17

Sorry, but I find your question incomprehensible.

Please try again - this time explaining clearly exactly how you are using the 
“LIVE555 Streaming Media” software (at both the server end, and/or client end, 
as appropriate), and what specific problem(s) you are encountering.
