format conversion

[Savio Sebastian]

Hi all,
How can convert the I420 format generated by v4l2src to AYUV as i am using videomixer.
I am using videomixer to mix videotestsrc and v4l2src.As videomixer can't accept the format provided by v4l2src which is I420,so i have to convert to AYUV which is provided by videotestsrc

So,How can the videomixer used to mix videotestsrc and v4l2src
with regards

Use ffmpegcolorspace or cogcolorspace between the source and videomixer.
In newer releases videomixer supports I420 though but it still requires
the same format on all sinkpads.
