    DXVA2 Copy-Back mode freezes issue on RX460


      Hi,this issue still exists in 16.10.2 in my case.


      This is the step how to re-produced the issue :

      1.In MPC-HC 64bit, enable LAV0.68.1 + DXVA2 Copy-Back mode

      2.Play a DXVA enabled video(the video must longer than 15 min.) for about 10~15 minutes.

      3.While video is still playing, click on time-slider bar to roll-back to early time point.

      Then it freezes MPC-HC.


      This is my LAV setting :



      The good part is this did not cause driver crash or fan 100% or PC freezes. I can use PC normally after forcing to terminate MPC-HC process.

      Also DXVA2 Native mode has no issue.


      I had reported it to AMD Issue Form, I post it here if anyone have DXVA issue can notice this part.
