As far as I've understood, anything in a gnlcomposition must be a compliant non-linear bin element, meaning I cannot just place those filters cascaded after a gnlfilesource. I guess the proper way to do so would be to have further gnloperation elements to take care of those operations, but I haven't managed so far to understand whether or not a gnlcomposition can contain more than a single gnloperation at all. If so, how can I have a specific gnlfilesource attach to a specific gnloperation taking care of it, and then have this be the source of the data to feed to the videomixing gnloperation itself? I tried playing a bit with the 'pad-added' signals but I couldn't do anything in that sense<BR>

Let's say you have two video streams that's you like to crop before mixing, you could have the following gnlcomposition:
<PRE>
1. [OP videomixer ]
2. [OP crop-1 num-sinks=1 ]
3. [SRC video-1 ]
4. [OP crop-2 num-sinks=1 ]
5. [SRC video-2 ]
