[Live-devel] HELP - AMR support using RTSP

[Moretzky Sarit]

Hi Ross,

Thank you 4 yr help :)
I tried what you suggested  - I created 2 raw files using the "openRTSP"
util and re-stream these files using "testMPEG4VideoStreamer" 
and "testAMRAudioStreamer" and what I found out is that I can not hear
the audio(amr) correctly. The sound is corrupted.

When I play my original 3gp file (RTSP
rtsp://192.118.51.178:554/videoBlogger/test.3gp) using QuickTime player
- I hear the audio clearly, so I know there is no problem with the
streaming server I use.

Does it maen that live.cot does not support AMR? Can you tell me what I
should do to make it support amr?
I really need my VLC to read stream that includes AMR and to be able to
play it correctly and I thought that changes in the Live.com lib can
help. Pls help.

Thanks
Sara

Yes it can, but (currently) not as a ".mov" or ".mp4" file.  Instead,
you 
will need to run "openRTSP" *without* the "-q" or "-4" options, so that
it 
writes audio and video as separate files - i.e.,

         openRTSP rtsp://192.118.51.178:554/videoBlogger/test.3gp

will create two files: a (raw) MPEG-4 video file, and an AMR audio 
file.  If you then rename these files as "test.m4v" and "test.amr" 
(respectively), you should be re-stream them using
"testMPEG4VideoStreamer" 
and "testAMRAudioStreamer" (respectively), or "testOnDemandRTSPServer"
(for 
unicast streaming), and play the resulting streams in QuickTime Player.

If all this works, then this will show that there's nothing wrong with
your 
server or with the LIVE.COM client code, and that any problems that you 
have receiving/playing AMR audio RTP streams in VLC must be due to the
VLC 
code itself.
