>
> Write a video compositing handler that takes n streams and arranges them
> together into a single stream for legacy players or download. The format of
> a template should be xml, something like:
> <canvas background="colorname">
> <stream src="friendlyname0" position="top,left" size="width,height"/>
> <stream src="friendlyname1" position="top,left" size="width,height"/>
> <stream src="friendlyname2" position="top,left" size="width,height"/>
> </canvas>
> This can then be turned into a gstreamer command like:
> gst-launch-0.10 videotestsrc pattern=1 ! video/x-raw-yuv, width=320,
> height=240 ! videomixer name=mix background=black ! ffmpegcolorspace !
> xvimagesink videotestsrc pattern=0 ! video/x-raw-yuv, width=800, height=600 !
> videobox border-alpha=0 top=0 left=-320 ! mix.
