dav2mkv 1.0.4

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

dav2mkv

Convert DAV and other video files to MKV or MP4 with FFmpeg stream copy — no re-encoding, no quality loss.

Quick start

pip install dav2mkv
dav2mkv -f recording.dav -o recording.mkv

Requires Python 3.12+ and FFmpeg (with ffprobe) on your PATH.

A standalone Windows executable is available on GitHub Releases.

Features

• Lossless conversion via direct stream copy
• Single-file or batch directory processing with optional recursion
• Parallel workers for directory mode
• MKV or MP4 output (default: MKV)
• Stream and format probing before conversion
• Cross-platform (Windows, macOS, Linux)

Install FFmpeg

Platform	Command
Windows (winget)	winget install ffmpeg
Windows (manual)	gyan.dev builds — add bin to PATH
macOS	brew install ffmpeg
Ubuntu/Debian	sudo apt update && sudo apt install ffmpeg

Verify with ffmpeg -version and ffprobe -version.

Installation

pip install dav2mkv

From a clone (development):

pip install -e ".[dev]"

Usage

Single file

dav2mkv -f input.dav -o output.mkv
dav2mkv -f input.dav -o output.mp4 --container mp4

Directory (batch)

dav2mkv -d ./videos -o ./converted
dav2mkv -d ./videos -o ./converted --recursive --container mp4 -c 4

Directory mode scans for common video extensions (.dav, .avi, .mp4, .mkv, .mov, and others).

python -m dav2mkv ./videos ./converted --container mp4
