[Live-devel] openrtsp confused by server

[Gabriel Bouvigne]

On a specific server, openrtsp seems to be confused by an unusual server 
response, and does a teardown.

Here is the output from openrtsp:

Failed to get a SDP description from URL "rtsp://localhost/out_ds.mp4": 
no response code in line: "OPTIONS * RTSP/1.0"


And here is the server log:

It seems to me that openrtsp is confused by the second answer from the 
server. However, I am wondering why openrtsp is bailing out, as it 
successfully managed to issue a PLAY command.
