I was excited to try out the new HW transcoding features (hw decode on nvidia linux and zero-copy support) but the changelog failed to mention that the new ffmpeg requires driver 418.30 or higher.
Since I’m still running Debian stretch, the provider driver is still on 390.xx. The new stable (buster) does have a 418.xx version in the repository, but maybe people would like to know the changed requirements on the driver for this beta, so they can prepare and upgrade accordingly.
(stretch-backports does provide a 418.xx version, so I’m trying that now)
