re 1): Both width and height must be even.
re 2): set the matrix to use for the output. So yes.
re 3): you can only pick yuvXXXpNN formats to set the subsampling and bit
depth (XXX = { 420, 422, 444 }, NN = { [noValue -> 8 bpc], 10, 12 })
re 4): Yes.
re 5): Yes.
>From what I read in trac and Doxygen, I'd recommend you avoid using this
filter if you can...
