Tvheadend

Hello.
First of all, thank you for this great program.
I have used it for quite some time and I am very satisfied with its use.

But I would like to know how to configure it to be able to transcode with an nvidia card and thus be able to send the signal online to my second residence.
In principle I use a clean ubuntu 16.04 server.
and as much as I follow the manuals I find on the internet to be able to transcode the signal with ffmpeg, I can't get it to work.

The steps I follow are:
ubuntu server installation
installation of cuda.
ffmpeg installation with support envenc.
then install tvheadedn with nvenc enabled.

But something I have to do wrong because it doesn't work for me.

I guess a lot of people will be interested in making it work. so I hope to define the steps to follow for other users who are in this same situation.

thanks.

I'm a little awkward so I hope your help

a hug
