Interlaced H264 DXVA decoding on RX 480

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

No issue with any Nvidia card or old AMD HD card , but RX470 cannot play properly with DXVA

Re: Interlaced H264 DXVA decoding on RX 480

same on all RX cards, this is unfuriating, no fix with latest hotfix driver, how are AMD getting away with this, not one single tech site has picked up on this major flaw yet and i've mailed several, AMD must be paying them off

There are also two other open threads about this, AMD remaining totally silent.

Have you seen this, someone reckons they can get DXVA working by preventing CPU clock down use clock blocker.

Re: Interlaced H264 DXVA decoding on RX 480

did nothing for me, suspect he was referring to the black screen issue and no the DVXA problem.
