First, are you sure that you should be adding "-s 0"? (If the RTP
payload format includes a special header, then this option will
(incorrectly) include it in the output.)
Second, I assume that you modified the "testOnDemandRTSPServer" code
as described in http://www.live555.com/liveMedia/faq.html#liveInput-unicast
I suggest that you first try breaking your command into separate steps:
openRTSP -v ... > testFile
testOnDemandRTSPServer < testFile
If this doesn't work either, then you may need to increase your OS's
socket buffering in "openRTSP"; see
If, however, the separate steps work, but piping doesn't, then you
probably need to (somehow) increase the buffer size that your OS uses
> 2. I try to modified testMPEG4VideoStreamer and merge it into openRTSP.
I don't recommend this. Remember that once you make major
modifications like this to the existing code, you can't expect much
support (especially with a "@gmail.com" email address).
