|
|
|
|
*
|
|
|
|
* VideoAggregator can accept AYUV, ARGB and BGRA video streams. For each of the requested
|
|
|
|
* sink pads it will compare the incoming geometry and framerate to define the
|
|
|
|
* output parameters. Indeed output video frames will have the geometry of the
|
|
|
|
* biggest incoming video stream and the framerate of the fastest incoming one.
|
|
|
|
*
|
|
|
|
* VideoAggregator will do colorspace conversion.
|
|
|
|
*
|
|
|
|
* Zorder for each input stream can be configured on the
|
|
|
|
* #GstVideoAggregatorPad.
