radeon_vid (or vidix itself) doesn't work with rgb surfaces (but reports
that it does). -bpp is no use at all. If the filter chain you use
outputs some kind of rgb by default, you'll see distortion.

Try playing just with -vf pp first (just to test it works). Then, try
adding scale,format=yv12 (or yuy2) to the end of your filter chain.

My default filter chain (suited for animation) is
vf = pp=hb:c/vb:c/dr:c/al:f,hqdn3d,noise=10uah,eq2

It gives no problems.

Other color anomalies are possible in rgb or yuv colorspaces, but I
never encountered them in vidix on radeons. Just for completeness,
filters like rgb2bgr, swapuv & noformat can help you with them.
