FFmpeg Container

A lightweight Docker container for running FFmpeg commands.

This container provides a ready-to-use FFmpeg environment for video and audio processing. It's built on Alpine Linux to maintain a small footprint while including common FFmpeg codecs and tools.

Usage

Pull and run the container:

docker pull onerahmet/ffmpeg
docker run --rm -v "$(pwd):/workspace" onerahmet/ffmpeg -i input.mp4 output.mp4

The -v "$(pwd):/workspace" flag mounts your current directory to /workspace inside the container, allowing FFmpeg to access your local files.

Example Commands

1. Convert video format:

docker run --rm -v "$(pwd):/workspace" onerahmet/ffmpeg -i input.mp4 output.mkv

2. Extract audio from video:

docker run --rm -v "$(pwd):/workspace" onerahmet/ffmpeg -i input.mp4 -vn -acodec libmp3lame output.mp3

3. Compress video:

docker run --rm -v "$(pwd):/workspace" onerahmet/ffmpeg -i input.mp4 -c:v libx264 -crf 23 -preset medium -c:a aac output.mp4

4. Create video thumbnail:

docker run --rm -v "$(pwd):/workspace" onerahmet/ffmpeg -i input.mp4 -ss 00:00:01 -vframes 1 -q:v 2 thumbnail.jpg

Building the Container

The container requires specifying an FFmpeg version during build:

docker build --build-arg FFMPEG_VERSION=n7.1 -t onerahmet/ffmpeg:7.1 .

Available versions can be found in FFmpeg's release tags. For example:

• n7.1
• n6.0

Note: The FFMPEG_VERSION build argument is required. The build will fail if not provided.

Features

• Based on Alpine Linux for minimal image size (~120MB)
• Includes common FFmpeg codecs and tools
• Simple volume mounting for file access
• Supports all standard FFmpeg commands and options

Notes

• All commands are run from the /workspace directory inside the container
• Input and output files must be accessible in the mounted volume
• Use absolute paths or paths relative to the mounted directory
