3.2.5 RTSP OPTIONS

The OPTIONS request returns a list of supported RTSP commands. The command can be used to keep RTSP sessions alive by repeating the OPTIONS request at regular intervals. The session timeout time is specified by the timeout parameter returned from the SETUP command (see 3.2.6 RTSP SETUP).

The response to the OPTIONS command contains the additional header field:

Header field

Public

Description

Specify the supported RTSP commands.

Example 3:

List supported commands. The asterisk (*) makes the request apply to the server and not to a particular URL.

Request:

OPTIONS * RTSP/1.0

CSeq: 1

User-Agent: Axis AMC

Session: 12345678

Response:

RTSP/1.0 200 OK

CSeq: 1

Session: 12345678

Public: DESCRIBE, GET_PARAMETER, PAUSE, PLAY, SETUP, SET_PARAMETER, TEARDOWN

Date: Wed, 16 Jul 2008 12:48:48 GMT

Note

As indicated in the response, the GET_PARAMETER command is supported; there are however no parameters to retrieve.

3.2.6 RTSP SETUP

The SETUP command is used to configure the data delivery method.

The SETUP request requires an additional header field which is also included in the response:

Header field

Transport

Description

Specify how the data stream is transported. Supported variants are:

RTP/AVP;unicast;client_port=port1-port2

RTP/AVP;multicast;client_port=port1-port2

RTP/AVP/TCP;unicast

If using unicast in combination with TCP, it is recommended to increase the size of the RTP packets to 64 000 bytes (from the standard 1500 bytes), provided that the client can accept larger packets. Also for unicast streaming over RTP/UDP it might be beneficial to increase the packet size if no packets are dropped. The packet size is changed using the following header field in the SETUP request:

Header field

Blocksize

Description

Request a specific media packet size. The packet size should be a positive decimal number measured in octets.
