Screenshot of working pipeline

Ok, worked around my problem based on some help from wtay on IRC. Pasting
working pipeline and the chat log with Wim

<cschalle>wtay, hmm, if I am trying to mix two streams with different
colorimetry, do I need to use a videoconvert/vidoefilter to make them the same?
<wtay> cschalle, yes
<cschalle>Is the problem that the pipeline is not able to negotiate identical
caps between the two src caps ?
<wtay> very likely
<cschalle> wtay, if so, do putting in a fixed caps for the 'videoconverted'
stream fix it?
<wtay> yes, you should put a desired output caps
<cschalle> wtay, ok, that solved it. I guess ideally the pipeline should have
negotiated this by itself, but this works for now. Thanks a lot
<wtay> we can't reliable negotiate all inputs on a mixer to the same format
