File Formats, Renderers, and Codecs

"Codecs" in helix are broken into pieces to make a more extensible system.

  • File format plugins read a specific type of container file.
  • Renderer plugins decode a specific media format.
  • Encoder/Decoders are used by renderer plugins.

For any media format that you wish to support you must have plugins to read the container and render the format.
