Hello there,
(a). nvdec is automatically detected and enabled IF the nv-codec-headers
package is installed.
(b). nvdec is a bit misleading, as its' an alias to CUDA hwaccel. Can you
see cuda listed under -hwaccels? If so, its' present.

I'm trying to build a complete ffmpeg for use with jellyfin media server
and be able to use my nvidia GPU fully to reduce overhead of transcoding on
my server.
After successfully building the default binary provided by this build
script, I realised that ffmpeg compilation function was lacking
"--enable-nvdec" and added it and started a new build.
It completed successfully but eventhough the resulting binary shows the
enable in the list, querying ffmpeg with -hwaccels, -decoders and
-encoders, I still can't see any sign of *_nvdec.
Is it built-in ffmpeg or am I just lost?!?
Thanks,

Oh i see! I kind of knew there was some ambiguity surrounding that term because nvdec & nvenc used to be cuvid but thanks for confirming...
This is the output of my ffmpeg hwaccels... So I guess I'm all set.

Still weird that transcoding is taking so long... Most likely more a jellyfin issue though.
Thanks all...

Perhaps you can show us a sample command from Jellyfin, such as how it
calls up FFmpeg, etc?

Actually, weirdly enough my last build seems to run perfectly now..
Mind you I haven't tested subtitles and other features but it's a start.
