/**
|
|
* SECTION:element-testsrcbin
|
|
* @title: testsrc
|
|
*
|
|
* This is a simple GstBin source that wraps audiotestsrc/videotestsrc following
|
|
* specification passed in the URI (it implements the #GstURIHandler interface)
|
|
* in the form of `testbin://audio+video` or setting the "stream-types" property
|
|
* with the same format.
|
|
*
|
|
* This element also provides GstStream and GstStreamCollection and thus the
|
|
* element is useful for testing the new playbin3 infrastructure.
|
|
*
|
|
* ## The `uri` format
|
|
*
|
|
* `testbin://<stream1 definition>[+<stream2 definition>]`
|
|
*
|
|
* With **<stream definition>**:
|
|
*
|
|
* `<media-type>,<element-properties>,[caps=<media caps>]`
|
|
*
|
|
* where:
|
|
*
|
|
* - `<media-type>`: Adds a new source of type `<media-type>`. Supported
|
|
* values:
|
|
* * `video`: A #videotestsrc element will be used
|
|
* * `audio`: An #audiotestsrc will be used
|
|
* you can use it as many time as wanted to expose new streams.
|
|
* - `<element-properties>`: `key=value` list of properties to be set on the
|
|
* source element. See #videotestsrc properties for the video case and
|
|
* #audiotestsrc properties for the audio case.
|
|
* - `<media caps>`: Caps to be set in the #capsfilter that follows source elements
|
|
* for example to force the video source to output a full HD stream, you can use
|
|
* `video/x-raw,width=1920,height=1080`.
|
|
*
|
|
* Note that stream definitions are interpreted as serialized #GstStructure.
|
|
*
|
|
* ## Examples pipeline:
|
|
*
|
|
* ### One audio stream with volume=0.5 and a white video stream in full HD at 30fps
|
|
*
|
|
* ```
|
|
* gst-launch-1.0 playbin3 uri="testbin://audio,volume=0.5+video,pattern=white,caps=[video/x-raw,width=1920,height=1080,framerate=30/1]"
|
|
* ```
|
|
|
|
* ### Single full HD stream
|
|
*
|
|
* ```
|
|
* gst-launch-1.0 playbin3 uri="testbin://video,pattern=green,caps=[video/x-raw,width=1920,height=1080,framerate=30/1]"
|
|
* ```
|
|
*
|
|
* ### Two audio streams
|
|
*
|
|
* ```
|
|
* gst-launch-1.0 playbin3 uri="testbin://audio+audio"
|
|
* ```
