We present a video engine to implement video playback, editing and writing with JUCE

JUCE is a framework, that allows to write cross platform audio applications. To make it possible to create applications, where you can edit audio AND video in the same environment, we created an engine, that reads video files, allows creating video generators, playing back and writing videos.

The engine offers a range of classes, that represent audio visual media. The classes are:

  • AVMovieClip: a movie read from a file like mp4, mov or other
  • ImageClip: a still image
  • AudioClip: an audio from a file with no images
  • ComposedClip: This renders a sequence of other clips together

Inside a ComposedClip, each included clip goes through processing, where you can add audio plugins and Video effects, such as pan&zoom, colour adjustments etc. This is extensible, so you can write your own video effects as well.

Features available

We will add features as we go, these are the ones, that are already finished:

  • Reading of video files, video and audio synchronous
  • Normalise different sample rates and frame rates
  • Video plugins for image processing / colour adjustments etc.
  • Automatable parameters for video composition
  • Compositing of multiple videos or still images in layers (paint on top)
  • Alpha blending of clips to create different transitions
  • Audio plugins for clips

The rendering is done in software to be independent from any hardware constraints. We plan somewhere in the future to add hardware accellerated processing.

The library uses FFmpeg for reading and writing video files. FFmpeg is published under L-GPL, so it is up to the user to govern for their license as well. We include neither a JUCE nor a FFmpeg license. It is possible to add your own video and audio reading classes to use it in the engine.
