Kantera

Video composition and rendering kit for Rust, depends on FFmpeg and cairo.

Kantera supports you create simple videos from few Rust code (or Web-UI).

This is my challenging project.💪😬

Process for make video from Rust code:

1. Prepare assets (images, videos) on memory if you need.
2. Build renderer with render trait.
3. Render it use render_to_mp4 function.

TODO:

• Import videos
• Import images
• Text rendering with any font
• Output video with audio
• Web-UI as GUI
• Sound composition
• DSL for building renderer
• Multi-thread rendering
• Realtime hosting via WebRTC
• Documentation...

Requirement

You need install them:

• FFmpeg
• cairo

Usage

Example of video generating

$ cargo run --release --example demo

After a while, a video named out.mp4 will be output to current directory.

Web UI

$ cd kantera-web-ui/front
$ yarn install
$ yarn build
$ cd ..
$ cargo run --release

Then open localhost:8080 in your web browser.
