Comment (by JEEB):

 {{{
 [Parsed_scale_0 @ 0x3585ec0] w:320 h:240 fmt:yuv420p sar:0/1 -> w:320
 h:240 fmt:nv12 sar:0/1 flags:0x4

 So swscale specifically notes that it is limited range, which is why
 vf_scale appears to set that value to the AVFrame, and thus that is the
 only field set in the AVFrame as there is no further color information
 available.
