    libavfilter/scale2ref: Maintain main input's DAR · d32a6c36
    Kevin Mark authored
    The scale2ref filter will now maintain the DAR of the main input and
    not the DAR of the reference input. This previous behavior was deemed
    counterintuitive for most (all?) use-cases.
    
    Before:
    scale2ref=iw/4:ow/mdar
    in  w:320 h:240 fmt:rgb24 sar:1/1
    ref w:640 h:360 fmt:rgb24 sar:1/1
    out w:160 h:120 fmt:rgb24 sar:4/3 flags:0x2
    SAR: ((120 * 640) / (160 * 360)) * (1 / 1) = 4 / 3
    DAR: (160 / 120) * (4 / 3) = 16 / 9
    (main out now same DAR as ref)
    
    Now:
    scale2ref=iw/4:ow/mdar
    in  w:320 h:240 fmt:rgb24 sar:1/1
    ref w:640 h:360 fmt:rgb24 sar:1/1
    out w:160 h:120 fmt:rgb24 sar:1/1 flags:0x2
    SAR: ((120 * 320) / (160 * 240)) * (1 / 1) = 1 / 1
    DAR: (160 / 120) * (1 / 1) = 4 / 3
    (main out same DAR as main in)
    
    The scale2ref FATE test has also been updated.
