/**

|
* SECTION:element-gstintervideosrc
|
|
*
|
|
* The intervideosrc element is a video source element. It is used
|
|
* in connection with a intervideosink element in a different pipeline,
|
|
* similar to interaudiosink and interaudiosrc.
|
|
*
|
|
* <refsect2>
|
|
* <title>Example launch line</title>
|
|
* |[
|
|
* gst-launch -v intervideosrc ! queue ! xvimagesink
|
|
* ]|
|
|
*
|
|
* The intersubsrc element cannot be used effectively with gst-launch,
|
|
* as it requires a second pipeline in the application to send subtitles.
|
