Referenced by find_transport(), and rtsp_read_setup().

int RTSPMessageHeader::seq
char RTSPMessageHeader::session_id[512]

the "Session:" field.

This value is initially set by the server and should be re-transmitted by the client in every RTSP command.

char RTSPMessageHeader::location[4096]

the "Location:" field.

This value is used to handle redirection.

Definition at line 151 of file rtsp.h.

char RTSPMessageHeader::real_challenge[64]

the "RealChallenge1:" field from the server

Definition at line 154 of file rtsp.h.

char RTSPMessageHeader::server[64]

the "Server: field, which can be used to identify some special-case servers that are not 100% standards-compliant.

We use this to identify Windows Media Server, which has a value "WMServer/v.e.r.sion", where version is a sequence of digits (e.g. 9.0.0.3372). Helix/Real servers use something like "Helix [..] Server Version v.e.r.sion (platform) (RealServer compatible)" or "RealServer Version v.e.r.sion (platform)", where platform is the output of $uname -msr | sed 's/ /-/g'.

Definition at line 163 of file rtsp.h.

int RTSPMessageHeader::timeout

The "timeout" comes as part of the server response to the "SETUP" command, in the "Session: <xyz>[;timeout=<value>]" line.

It is the time, in seconds, that the server will go without traffic over the RTSP/TCP connection before it closes the connection. To prevent this, sent dummy requests (e.g. OPTIONS) with intervals smaller than this value.

Definition at line 171 of file rtsp.h.

int RTSPMessageHeader::notice

The "Notice" or "X-Notice" field value.

See http://tools.ietf.org/html/draft-stiemerling-rtsp-announce-00 for a complete list of supported values.

Definition at line 176 of file rtsp.h.

char RTSPMessageHeader::reason[256]

The "reason" is meant to specify better the meaning of the error code returned.
