[Live-devel] Failed to read response: Success

[Scott Hays]

I'm writing an MPEG4 ES video streaming server for use with an MPEG4 encoder 
chip.  In my DeviceSource-derived class, I get the data from the encoder 
chip, add VS and VOL headers every second, and hand off the frame (plus any 
added headers) to MPEG4VideoStreamDiscreteFramer.  The rest of the server is 
derived directly from testMPEG4VideoStreamer.

When I try to receive a stream from the server using openRTSP, everything 
seems to be fine until openRTSP sends a SETUP request.  Then it just hangs 
until the server shuts down or I kill it.  Here's the output from the -V 
option:

Failed to setup "video/MP4V-ES" subsession: Failed to read response: Success
--------
ffplay complains with "Error while parsing header", but that's not very 
helpful, since of course it can't read a header it's not receiving.
Any suggestions on what I'm doing wrong?
