Encoder image

This Docker image contains an encoder script and a ffmpeg installation.

It encodes all files in the input folder of an SFTP server or the local volume /media/encoder/input. Multiple containers on the same directory are possible. The input folder contains some special folder which corresponds to arguments for the encode script.

Installation

1. Pull from Docker Hub, download the package from Releases or build using builder/build.sh
