## Object Hierarchy

        GObject
        ╰── GstRTSPMedia

## Description

a GstRTSPMedia contains the complete GStreamer pipeline to manage the streaming to the clients. The actual data transfer is done by the GstRTSPStream objects that are created and exposed by the GstRTSPMedia.

The GstRTSPMedia is usually created from a GstRTSPMediaFactory when the client does a DESCRIBE or SETUP of a resource.

A media is created with `gst_rtsp_media_new()` that takes the element that will provide the streaming elements. For each of the streams, a new GstRTSPStream object needs to be made with the `gst_rtsp_media_create_stream()` which takes the payloader element and the source pad that produces the RTP stream.

The pipeline of the media is set to PAUSED with `gst_rtsp_media_prepare()`. The prepare method will add rtpbin and sinks and sources to send and receive RTP and RTCP packets from the clients. Each stream srcpad is connected to an input into the internal rtpbin.

It is also possible to dynamically create GstRTSPStream objects during the prepare phase. With `gst_rtsp_media_get_status()` you can check the status of the prepare phase.

After the media is prepared, it is ready for streaming. It will usually be managed in a session with `gst_rtsp_session_manage_media()`. See GstRTSPSession and GstRTSPSessionMedia.

The state of the media can be controlled with `gst_rtsp_media_set_state()`. Seeking can be done with `gst_rtsp_media_seek()`.

With `gst_rtsp_media_unprepare()` the pipeline is stopped and shut down. When `gst_rtsp_media_set_eos_shutdown()` an EOS will be sent to the pipeline to cleanly shut down.

With `gst_rtsp_media_set_shared()`, the media can be shared between multiple clients. With `gst_rtsp_media_set_reusable()` you can control if the pipeline can be prepared again after an unprepare.

The RTSP media class

#### Members

GObjectClass `parent_class`; |  |
`handle_message` () | handle a message |
`prepare` () | the default implementation adds all elements and sets the pipeline's state to GST_STATE_PAUSED (or GST_STATE_PLAYING in case of NO_PREROLL elements). |
`unprepare` () | the default implementation sets the pipeline's state to GST_STATE_NULL and removes all elements. |
`suspend` () | the default implementation sets the pipeline's state to GST_STATE_NULL GST_STATE_PAUSED depending on the selected suspend mode. |
`unsuspend` () | the default implementation reverts the suspend operation. The pipeline will be prerolled again if it's state was set to GST_STATE_NULL in suspend. |
`convert_range` () | convert a range to the given unit |
`query_position` () | query the current position in the pipeline |
`query_stop` () | query when playback will stop |
`create_rtpbin` () |  |
`setup_rtpbin` () |  |
`setup_sdp` () |  |
`new_stream` () |  |
`removed_stream` () |  |
`prepared` () |  |
`unprepared` () |  |
`target_state` () |  |
`new_state` () |  |
`handle_sdp` () |  |

### enum GstRTSPMediaStatus

The state of the media pipeline.

#### Members

GST_RTSP_MEDIA_STATUS_UNPREPARED | media pipeline not prerolled |
GST_RTSP_MEDIA_STATUS_UNPREPARING | media pipeline is busy doing a clean shutdown. |
GST_RTSP_MEDIA_STATUS_PREPARING | media pipeline is prerolling |
GST_RTSP_MEDIA_STATUS_PREPARED | media pipeline is prerolled |
GST_RTSP_MEDIA_STATUS_SUSPENDED | media is suspended |
GST_RTSP_MEDIA_STATUS_ERROR | media pipeline is in error |

### enum GstRTSPSuspendMode

The suspend mode of the media pipeline. A media pipeline is suspended right after creating the SDP and when the client performs a PAUSED request.

#### Members

GST_RTSP_SUSPEND_MODE_NONE | Media is not suspended |
GST_RTSP_SUSPEND_MODE_PAUSE | Media is PAUSED in suspend |
GST_RTSP_SUSPEND_MODE_RESET | The media is set to NULL when suspended |
