[Live-devel] Play/Pause Commands not honoured

[ziyad sharafudheen]

Hi,

I am using live555 rtsp server for video streaming. The transport used is
tcp with interleaved (but not sending receiver reports).

Trick mode options are not working for us. Play request with normal scale
works perfectly (we get the ok response), but when we send a play request
for 2x, 4x etc, the live555 server does not respond with OK. The behavior is
the same when we issue pause request after a play request.

I have pasted below the rtsp packet exchange happening between server and
client. The last request (in bold) is a play request with 2x scale for which
the server has not responded. Kindly help us in proceeding further.
