I’m just making this topic as a precaution because the latest builds of FFmpeg for my distribution have migrated to building with nv-codec-headers SDK version 12.0, which bumps the required NVIDIA driver from 470 to 520, effectively dropping support for hardware transcoding on Kepler series cards (listed here).
So, to the Plex team: If possible, please don’t make the same change (building Plex Transcoder with nv-codec-headers >=12) so all of us with older cards can utilising hardware transcoding!
If you need to upgrade to version 12 and above for any particular feature, please consider including a build with 11.1 to fall back on in case of the following FFmpeg error:
Driver does not support the required nvenc API version. Required: 12.0 Found: 11.1
The minimum required Nvidia driver for nvenc is 520.56.06 or newer
