Change videosrc element ordering
GStreamers basetransform has a nasty issue where its caps negotiation doesn't
keep the ordering of caps when unioning, as a result of this linking the
pipeline as "<src> ! videoscale ! colorspace ! video/x-raw-yuv" means at the
<src> element yuv is no longer preferred.
Changing the pipeline to be "<src> ! colorspace ! videoscale ! video/x-raw-yuv"
forces the videoscale to only negotiate video/x-raw-yuv, which in turns ensures
the colorspace and <src> element pick the right colorspace.
In combination with emulated formats in v4l2src picking the wrong colorspace
causes quite a performance hit (the src would do a color conversion in libv4l,
while the colorspace element would later convert it back to a colorspace
actually native to the src device!)
