Convert DAV/video files to MKV/MP4 via FFmpeg stream copy

DAV2MKV: The Ultimate DAV to MKV/MP4 Converter

A Python command-line tool for converting DAV video files to MKV or MP4 while maintaining perfect quality through stream copying. dav2mkv uses FFmpeg to perform direct stream copy operations, ensuring no quality loss during conversion.

Features

• Direct stream copy (no quality loss)
• Maintains all original streams (video, audio, subtitles)
• Batch processing with parallel directory conversion
• Convert a single file or an entire folder of files
• Specify the output container format (MKV or MP4, default is MKV)
• Display detailed video information before conversion
• Progress tracking
• Cross-platform compatibility (Windows, macOS, Linux)

Prerequisites

1. Python 3.12+
2. FFmpeg and FFprobe installed and available in your system PATH

Installing FFmpeg

FFmpeg can be installed using various package managers or directly from its website:

Windows

• Download the latest static build from gyan.dev.
• Extract the files and add the bin folder to your system's PATH.
• Use a package manager:
  • Winget:

    winget install ffmpeg
    

  • Chocolatey:

    choco install ffmpeg-full
    

macOS

• Use Homebrew:

  brew install ffmpeg
  

Linux

    sudo apt update && sudo apt install ffmpeg
    

  • Fedora:

    sudo dnf install ffmpeg
    

  • Arch:

    sudo pacman -S ffmpeg
    

Installation

pip install dav2mkv

For development:

pip install -e ".[dev]"

A standalone Windows executable is also published on GitHub Releases.

Usage

dav2mkv -f input.dav -o output.mkv
dav2mkv -d ./videos -o ./converted --container mp4 --recursive
python -m dav2mkv input.dav ./converted --container mp4

Options

• -f, --file: Single video file to convert
• -d, --directory: Directory containing video files to convert
• -o, --output: Output file or directory
• --container: mkv or mp4 (default: mkv)
• --recursive: Process subdirectories (directory mode)
• -c, --concurrent: Parallel workers (directory mode)
• --log-level, --log-file: Logging options

Development

Run local quality checks:

py scripts/verify.py

Apply formatting fixes before checks:

py scripts/verify.py --fix

Notes

• Ensure FFmpeg and FFprobe are correctly installed and accessible from the command line.
• For directory conversion with a separate output folder, use -o to specify the destination directory.
