Detailed Description

Real Time Streaming Protocol (RTSP) implementation - rfc 2326.

RTSP Layer

The RTSP module requests the media streams and handles the service handshake. Once this phase is complete it behaves like a remote controller for the requested multimedia stream.

Variable Documentation

char* rtsp_session_s::body [inherited]

Contains the raw describe response. It should be NEVER accessed directly. All the data is available through rtsp_session_info.

Definition at line 124 of file rtsp.h.

Referenced by rtsp_reinit().

char* rtsp_session_s::content_base [inherited]

Not NULL if a Content-Base field is found in the response to the DESCRIBE method. In this case the field pathname and all the rtsp_medium of the session are relative to content_base path.

Definition at line 110 of file rtsp.h.

Referenced by rtsp_reinit().

int rtsp_session_s::CSeq [inherited]

Last sent RTSP packet sequence number

Definition at line 105 of file rtsp.h.

char* rtsp_medium_s::filename [inherited]

Medium identifier. Used for the ``per medium'' methods (SETUP, TEARDOWN).

Definition at line 80 of file rtsp.h.

Referenced by rtsp_info_print().

sdp_session_info* rtsp_session_s::info [inherited]

Session informations

Definition at line 116 of file rtsp.h.
