  74 Videomixer2 can accept AYUV, ARGB and BGRA video streams. For each of the requested
  75 sink pads it will compare the incoming geometry and framerate to define the
  76 output parameters. Indeed output video frames will have the geometry of the
  77 biggest incoming video stream and the framerate of the fastest incoming one.
  78 </p>
  79 <p>
  80 All sink pads must be either AYUV, ARGB or BGRA, but a mixture of them is not
  81 supported. The src pad will have the same colorspace as the sinks.
  82 No colorspace conversion is done.
  83 </p>
  84 <p>
  85 Individual parameters for each input stream can be configured on the

  89 At this stage, videomixer2 is considered UNSTABLE. The API provided in the
  90 properties may yet change in the near future. When videomixer2 is stable,
  91 it will replace <span class="type">videomixer</span>
