	This is a small example about how to use {{VLC}} to create a mosaic. What we basically want is a video mosaic mixing 3 video channels (channels 1, 2 and 3) on a background image (background.png) and streaming the resulting video on the network. Note that we will also be streaming the 3 sound tracks from channels 1, 2 and 3 in the same ~~mpeg~~-ts stream.		This is a small example about how to use {{VLC}} to create a mosaic.

			Alternatively, one can setup a mosaic directly from files using a vlm configuration file as the follwing :

			<pre>
			new channel1 broadcast enabled
			setup channel1 input file:///path/to/movie.mp4
			setup channel1 output #duplicate{dst=mosaic-bridge{id=1,height=366}}

			new channel2 broadcast enabled
			setup channel2 input file:///path/to/movie.mp4
			setup channel2 output #duplicate{dst=mosaic-bridge{id=2,height=366}}

			new channel3 broadcast enabled
			setup channel3 input file:///path/to/movie.mp4
			setup channel3 output #duplicate{dst=mosaic-bridge{id=3,height=366}}

			new channel4 broadcast enabled
			setup channel4 input file:///path/to/movie.mp4
			setup channel4 output #duplicate{dst=mosaic-bridge{id=4,height=366}}

			new mosaic broadcast enabled
			setup mosaic input file:///path/to/background1600.png
			setup mosaic output #transcode{sfilter=mosaic,vcodec=mp4v,VB=20000,acodec=none,fps=15,scale=1}:display

			control mosaic play
			control channel1 play
			control channel2 play
			control channel3 play
			control channel4 play
			</pre>

			To write the resulting stream to a file, the mosaic output line may also be replaced by :
			<pre>
			setup mosaic output #transcode{sfilter=mosaic,vcodec=mp4v,VB=20000,acodec=none,fps=15,scale=1}:standard{access=file,mux=ogg,dst="output_file.ogg"}
			</pre>

	Note that the source streams are network streams, which is likely to be the case if you're considering doing a mosaic.		Note that the source streams are network streams, which is likely to be the case if you're considering doing a mosaic.
