C-Play is a open-source/free video/media player, intended use for science centers and/or public environments, with cluster environments where you need multiple computers and/or displays to run your content on. The displays could be flat or curved in any setup that is supported by our underlying toolkit SGCT[5] and any media format supported by mpv. The UI is built with Qt/QML.

Features

edit

These are just some features that set C-Play apart from others media/video players.

C-Play support videos that are:

  • Stereoscopic (Side-by-side or Top-Bottom) and Monoscopic
  • 180 fulldome / fisheye projection
  • 360 projections such as Equirectangular or Equi-Angular Cubemap (EAC), which is common on YouTube
  • Any “flat” video arbitary aspect ratio

Some technical features:

  • Runs a Qt/QML UI application on master computer and small none-UI GLFW/SGCT application on clients.
  • Sync playback, loading and other properties between master and clients.
  • Playing audio is only available on master. C-Play support change of audio output, and is pre-built with support for JACK, which opens for multi-channel low-latency output to for instance ASIO devices.
  • Loading external audio files as multiple tracks.
  • Editing and saving playlist and playfiles including all necassary parameters.
  • Configure “sections” in a editor to create bookmarks to jump between clips inside a larger movie.
  • Sync video+audio fade in/out
  • HTTP Web API
  • Tested and used on primarily Windows 10, in domes and other big arenas.

Packages

edit

Binaries/installer is distributed for Windows. However the public source code itself is cross-platform.

Limitations

edit

Testing and usage has so far only been done on Windows 10. If you need a media player for Linux and/or Mac, feel free to look into other front-end UI:s for mpv. This software is intended for usage with a master controling video on a secondary/multiple monitor(s) and/or multiple computers.

Syncronization

edit

Syncronization is currently only applied with the use of either time from the media or the video frequency. For clustered applications, it is strongly recommend to use frame synchronization betweem the computers, that can be performed utilizing NVIDIA Quadro or AMD FirePro synchronization cards.
