Docker-based FFmpeg and FFprobe Wrappers

Wrapper scripts for FFmpeg and FFprobe that run these tools inside a Docker container. These scripts allow you to use FFmpeg and FFprobe without installing them directly on your system. Goal: enable speech models like Whisper without installing ffmpeg + depedencies on the host.

Features

• Run FFmpeg and FFprobe commands using Docker
• Handle input from stdin and output to stdout
• Process local files by temporarily copying them into the Docker container
• Copy output files back to the host system
• Support for all FFmpeg and FFprobe command-line options

Prerequisites

• Docker
• Zsh shell

Installation

1. Clone this repository or download the script files.
2. Make the scripts executable:

   chmod +x ffmpeg ffprobe
   

3. Add the directory containing these scripts to your PATH:

   export PATH=$PATH:.
   

Usage

Use these scripts just as you would use the regular ffmpeg and ffprobe commands. The scripts will handle the Docker setup and file management automatically.

FFmpeg Example

./ffmpeg -i input.mp4 -c:v libx264 -crf 23 -c:a aac -b:a 128k output.mp4

FFprobe Example

./ffprobe -v quiet -print_format json -show_format -show_streams input.mp4

How It Works

1. The scripts create a temporary directory to store input and output files.
2. Input files are copied to this temporary directory.
3. The FFmpeg or FFprobe command is run inside a Docker container, with the temporary directory mounted as a volume.
4. Output files are copied back to the current directory.
5. The temporary directory is cleaned up.

Notes

• The scripts use the jrottenberg/ffmpeg Docker image.
• Input and output via stdin/stdout is supported.
• File paths in the command arguments are automatically adjusted for use within the Docker container.
