Top | Description |
Videomixer2 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.
All sink pads must be either AYUV, ARGB or BGRA, but a mixture of them is not supported. The src pad will have the same colorspace as the sinks. No colorspace conversion is done.
Individual parameters for each input stream can be configured on the GstVideoMixer2Pad.
