Keep the alphabetic ordering please.

I have no idea what this filter does and since the 
most important format (yuv420p) is supported, this 
doesn't really matter but yuv410p and yuva444p are 
quite exotic formats, I would at least have 
expected yuv422p, yuva420p and yuv444p in the list.

Did you test all above formats (at least the left row)?
