    Interlaced H264 DXVA decoding on RX 480

    buchanan

      Hello,

       

      It seems that DXVA decoding of interlaced H264 content on RX 480 is broken, I get this result :

      Here is the sample used : http://carte.fh.free.fr/meteo.ts

      The results are identical wether I use any of these players :

      - MPC-HC 1.7.10.252 x64 (internal LAV 0.68.1.25), DXVA2 native

      - MPC-HC 1.7.10.252 x64 (internal LAV 0.68.1.25), DXVA2 copy-back

      - VLC 2.2.4, DXVA2 hardware acceleration

       

      Progressive content is playing fine as far as I can tell.

       

      My config:

      Windows 7 64 bits

      AMD Radeon RX 480, 16.7.1 driver

      Intel core I7 4960X, 24GB RAM
