Enumeration Type Documentation

enum RTSPClientState

Client state, i.e.

whether we are currently receiving data (PLAYING) or setup-but-not-receiving (PAUSED). State can be changed in applications by calling av_read_play/pause().

Enumerator:

RTSP_STATE_IDLE	not initialized
RTSP_STATE_PLAYING	initialized and receiving data
RTSP_STATE_PAUSED	initialized, but not receiving data

Definition at line 142 of file rtsp.h.

enum RTSPLowerTransport

Network layer over which RTP/etc packet data will be transported.

Enumerator:

RTSP_LOWER_TRANSPORT_UDP	UDP/unicast.
RTSP_LOWER_TRANSPORT_TCP	TCP; interleaved in RTSP.
RTSP_LOWER_TRANSPORT_UDP_MULTICAST	UDP/multicast.
RTSP_LOWER_TRANSPORT_NB

Definition at line 33 of file rtsp.h.

enum RTSPServerType

Identifies particular servers that require special handling, such as standards-incompliant "Transport:" lines in the SETUP request.

Enumerator:

RTSP_SERVER_RTP	Standards-compliant RTP-server.
RTSP_SERVER_REAL	Realmedia-style server.
RTSP_SERVER_WMS	Windows Media server.
RTSP_SERVER_NB

Definition at line 152 of file rtsp.h.

enum RTSPTransport

Packet profile of the data that we will be receiving.

Real servers commonly send RDT (although they can sometimes send RTP as well), whereas most others will send RTP.

Enumerator:

RTSP_TRANSPORT_RTP	Standards-compliant RTP.
RTSP_TRANSPORT_RDT	Realmedia Data Transport.
RTSP_TRANSPORT_NB

Definition at line 45 of file rtsp.h.
