Helix Plugins

The Helix Media engine uses a plugin system to provide an extensible framework. The purpose of this list is to describe in detail, the files that may be contained within a Watch & Listen bundle. This list may not be exhaustive but should contain most plugins.

All of the listed plugins are available under the GPL or RPSL. They can all be built from source available on HelixCommunity.org. However, not all plugins (codecs) are royalty free.

Engine

These plugins make up the helix engine. They all perform a specific function.

File Name Description License
authmgr.so Authentication manager
clbascauth.so
clntxres.so
colorcvt.so Color Converter Plugin contains functions for converting between different types of color formats (ie. YUV -> RGB)
httpfsys.so HTTP File System Plugin for dealing with files retrived via the HTTP protocol
hxplay.so HXPlay Python extensions for the helix media player GPL / RPSL
hxmedpltfm.so
hxmedplyeng.so
hxnetwksvc.so
memfsys.so Memory Filesystem Reads media stored in memory
rn5auth.so
smplfsys.so Simple Filesystem Plugin for reading files from the local filesystem
vidsite.so Video Site Plugin for handling video output. Handles both creating windows and video overlays.

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.

Free Formats

These plugins are completely free.
