VAAPI video converter
A Docker-based video converter that uses VAAPI-compatible hardware for transcoding
Key features
- Transcode a video
- Keep only the main video and a single audio track
- Use hardware-acceleration to unburden the CPU
- Use docker to keep the system clean of dependent packages
Pre-requisites
- A linux system with
docker-compose
On debian-based systems, docker-compose may be installed by calling
$ sudo apt install docker-compose
Examples
Convert a video to a small MP4 with stereo audio in german for use on a mobile device:
$ ./start /media/input.mkv /tmp/output.mp4
Use italian language; if not available, use english as fallback:
$ AUDIO_LANGUAGES=ita,eng ./start /media/input.mkv /tmp/output.mkv
Create output video with permissions for user with user id and group id 1000:
$ PUID=1000 PGID=1000 ./start /media/input.mkv /tmp/output.mp4
