ffmpeg-vaapi-docker

Autmatic transcoding of files in watched folder with vaapi / gpu support.

It is based on newest ubuntu:jammy for recent mesa support. should work with amd and intel gpu. Tested on amdgpu polaris with base system debian 9 and 5.15.21-xanmod1 kernel.

This is a very simple docker image that watches a folder for files and tries to transcode them. I made this since I found no possibility of easy hw transcoding on my dated debian 9. Handbrake only supports recent ubuntu with full amd packages installed. Mesa versions on debian 9 are too old to support.

1. Clone repo and enter folder
2. Build the image: docker build -t praul/ffmpeg .
3. Create a convert dir somewhere and change docker-compose.yml accordingly. The folder has to be mounted inside the container at /convert
4. Start a container with docker-compose: docker-compose up -d
5. Put files in your convert/source folder. They will be transcoded.
6. If you want to change the ffmpeg settings, change app/convert.sh and mount it in the container to /app/convert.sh
7. Default convert settings are 2M Bitrate, HEVC. To change, edit ffmpeg command at -b:v 2M -c:v hevc_vaapi
