Pipeline for three inputs

[iron_guitarist1987]

I created a plugin that takes in three videos. The pads are static always pads. My question is what would be the correct pipeline to run this. For two inputs I have:

    gst-launch -v videotestsrc ! multivideos name=s ! ffmpegcolorspace ! ximagesink videotestsrc ! s.

Would this be good for three inputs?

    gst-launch -v videotestsrc ! multivideos name=s ! ffmpegcolorspace ! ximagesink videotestsrc videotestsrc! s.

With this pipeline, I'm getting the error below. Is this the wrong pipeline, or could something be wrong with the code.

$ gst-launch -v videotestsrc ! multivideos name=s ! ffmpegcolorspace ! ximagesink videotestsrc videotestsrc! s.

That middle videotestsrc is dangling, not connected to anything, so
add another "! s." after it. Interesting that sink2 and 3 are
connected first, I should check out how pads are chosen when not
specified directly.
