Subject: avcodec/vdpau: Enable HEVC support for working Nvidia driver versions
X-Git-Tag: n4.2-dev~13

avcodec/vdpau: Enable HEVC support for working Nvidia driver versions

The driver bugs that caused decoded HEVC content to have an incorrect
memory layout have been fully fixed in the 410.xx driver release so
we can start exposing support.
