    DXVA2 broken and random black screens

    mclingo

      ok, so I get this card is new but it really is a mess. Here is a list of some issues i've had.

       

      SOLVED ISSUES

       

      1. BSOD when playing movies. Not knowing DXVA was broken this may have been the cause but the BSOD's stopped when I rebuilt my PC, 2 days wasted perhaps.

      2. Unable to set PIXEL format. I tracked this down to DEEP COLOUR on my 4K tv, if you have a 4K TV you cant change pixel format unless DEEP colour is on, this is pants and clearly a bug, this wasn't fixed by a PC rebuild so its clearly an ATI issue.

       

      UNFIXED

       

      1. DXVA2 h264 is broken big style, I get severe video artifacts when I skip through movies and playback is generally not smooth and glitchy. Current workaround is to turn off H264 in LAV filters, hardly ideal when you've just shelled out £230 for high end card.

       

      2. I get totally random black and blue screens, sometime black, sometimes light blue. The PC is still working but the monitor connection is dead and will not wake up even with HDMI YO, it requires a full reboot, this is ****ing annoying to say the least.

       

      3. Lets face it we all heated the control center but my god crimson is even worse, what a mess, did ATI get a 5 year old in to design that?

       

      If ATI dont get a driver out to fix DXVA in the 7 days its going back and i'll give the 1060 a go.

          and now i'm back to BSODs again THREAD STUCK IN DEVICE DRIVER - dxgkrnl.sys

           

          I think this might be the last straw..AMD you are a set of tossers.

              Hi

              I have similar problem on RX460, but I do not have artifacts , just driver stopped or BSOD(THREAD STUCK IN DEVICE DRIVER) in different scenario. Maybe you already read my post:

              DXVA on RX460 , 0Mhz reading questions.

               

              These are my scenarios :

              1.LAV 0.68.1 :

              I have issue on DXVA2 copy-back, but DXVA2 native seems fine in LAV.

               

              2.Chrome version 53.0.2785.89 m (64-bit) :

              I use h264ify plugin to force h264 decoding on youtube.

              3.Firefox 48.0.2 and same scenario as described above.

               

              4.Microsoft Edge 38.14393.0.0  and same scenario as described above.

               

              In my case I am fine with DXVA2 native on LAV, but in browsers there is no way to change it. So I still have issue with:

              Chrome 53.0.2785.89 m (64-bit)

              Firefox 48.0.2

              Microsoft Edge 38.14393.0.0.
