FFMPEG Code error 1 (Is this dead ? Any alternative ?)

[Kazz3r24]

This project unfortunately seems dead now. No real updates in a few years. Using ffmpeg 4.2.4 on Ubuntu 20 I get the same error as you, with ffmpeg 3.4.8 on Ubuntu 18 it works fine. I'll try your edit with the disposition metadata to see if I can get mine working as well. I have 2 servers, it works on one and not the other.

I've been looking for ages for either a fix or an alternative. This fork may still be being actively worked on.

I just tried this out from another issue post on this repo, it worked for me just now. If installed via npm

sudo npm uninstall h265ize --global
git clone https://github.com/FallingSnow/h265ize
cd h265ize
sudo npm install --global

Maybe https://github.com/cdgriffith/FastFlix will work for you
