Comment 32 for bug 1816497

HW acceleration doesn't work for me in the latest build. I noted that Olivier was going to build with a newer version of libva so I went ahead an installed the latest version, as per this guide: https://github.com/intel/media-driver/wiki/How-to-build-and-use-media-driver%3F. Unfortunately that did not change the behavior, so I still see kVideoDecoderName="VpxVideoDecoder"
