transform could not transform video/x-raw-yuv

[Chuck Crisler]

It seems like something in your caps must be causing the problem. First,
look again at gst-inspect for each of your elements. I guess that the
problem is with ffmpegcolorspace because the decoder should turn out I420.
You could confirm this by setting GST_DEBUG=*2,GST_ELEMENT_PAD=4 and maybe
something else (GST_ELEMENT=4?). It may be that, for the output you
specify, ffmpegcolorspace can't use the decoder output or (more likely)
just can't generate the requested output format period.
