RTSP server

|
-----------
|

|
|
|
||
|
|
This directory contains an example RTSP server built with various GStreamer
|
||
|
|
components and libraries. It also uses GStreamer for all of the multimedia
|
||
|
|
procesing and RTP bits. The following features are implemented:

Server Design
|
||
|
|
-------------
|
||
|
|
|
||
|
|
The toplevel component of the server is a GstRTSPServer object. This object
|
||
|
|
creates and binds on the server socket and attaches into the mainloop.
|
||
|
|
|
||
|
|
For each request a new GstRTSPClient object is created that will accept the
|
||
|
|
request and a thread is started to handle further communication with the
|
||
|
|
client until the connection is closed.
|
||
|
|
|
||
|
|
When a client issues a SETUP request we create a GstRTSPSession object,
|
||
|
|
identified with a sessionid, that will keep track of the state of a client.
|
||
|
|
The object is destroyed when a TEARDOWN request is made for that sessionid.
|
||
|
|
|
||
|
|
We also maintain a pool of URL to media pipeline mappings. Each url is mapped to
|
||
|
|
an object that is able to provide a pipeline for that media. We provide
|
||
|
|
pipelines to stream live captured data, on-demand file streaming or on-demand
|
||
|
|
transcoding of a file or stream.
|
||
|
|
|
||
|
|
A pool of currently active pipelines is also maintained. Usually the active
|
||
|
|
pipelines are in use by one or more GstRTSPSession objects. An active pipeline
|
||
|
|
becomes inactive when no more sessions refer to it.
|
||
|
|
|
||
|
|
A client can choose to start a new pipeline or join a currently active pipeline.
|
||
|
|
Some active pipeline cannot be joined (such as on-demand streams) but a new
|
||
|
|
instance of that pipeline can be created.
