    DXVA2 not supported in LAV video decoder



      I'm facing a trouble with enabling DXVA2 support in LAV video decoder. I have updated AMD crimson drivers to the latest version available but still the DXVA2(both "native" and "copy-back") options of the LAV video decoder doesn't show my AMD Radeon HD8750M card. Added system info and screenshots of "Radeon Settings" application & LAV Video Decoder Configurations.

      Is there any metgod to solve this issue? Please help.

          Hi, i just solved the issue. I didn't do anything special to solve it actually ha-ha. I played a video using the video player (PotPlayer) which was added to performance mode in "AMD switchable Graphics" and opened the "LAV video configurations" then my dedicated gpu "AMD Radeon HD8750M"was appeared in the "Hardware devices to use" list. However due to error suddenly appeared in GPU temp after installing "Crimson Drivers", i uninstalled those "Crimson drivers" and installed drivers provided by HP for my laptop's dedicated GPU. Now LAV Decoder issue is solved but most of the time AMD GPU's temp is shown as 511c according to Speccy.

              Thanks for letting us know.


              The HP notebook’s internal display panel is wired to the Intel HD Graphics integrated GPU, so without setting the application to high performance mode and forcing it to run on the AMD GPU, you will always use the Intel device when watching videos on the notebook display.
