Changes (by Balling):

 * status:  reopened => closed
 * resolution:   => invalid

Comment:

 The obvious problem here is that swscale defaults to YCbCr limited range,
 so what should be done is -vf scale=out_range=pc and you may also want to
 specify -color_range pc to tag it.

 yuvj4xxp are deprecated and should not be used.
