MAV: Mojo Audio Video
Low level FFmpeg (8.*) bindings to Mojo for audio, image, and video processing. The bindings are avilable via the mojo community channel (Note the installation section below.
Emphasis should be placed on Low Level. This repo will never provide a high level API.
This project is originally part of ash_dynamics, but has been separated out to be used by other projects.
This package uses ffmpeg 8.0.1 from conda-forge. Please see the LICENSE section for more information.
High Level API Reference
Its strongly recommended to use the native FFmpeg C examples for now.
High Level API Current Projects Using MAV
- momanim (Early development)
Goals
My goals with mojo involves robot training and simulation, however we have not had a nice way to visualize renderings. This repo + momanim is where I’m playing with / learning high performance rendering using mojo, hopefully eventually rolling into robot simulation.
Demo / Examples in Mojo:
Video outputs from tests/test_ffmpeg/test_video_example.mojo
Gif:
Additionally outputs mp4 and webm video files.
Image outputs from tests/test_ffmpeg/test_image_example.mojo
Png:

Installation
mav will install FFmpeg, however the Mojo compiler must be pointed to those libraries.
pixi.toml example. Reference the Current Projects above for practical usage.
