• Virtual Reality Video Compression

  • Completed 2015

The Cannes video codec builds upon the foundation of Chicago with support for mixed reality content including stereoscopic 3D, 360° panoramas, and spherical video. Similar to Chicago, Cannes was designed to serve as a testbed for further experimentation and research.



Experimental Video Codecs

EVX is a collection of five evolutionary codecs that are used for experimentation and education. They are not designed for productization and lack many important features and optimizations. Nonetheless, they are an extremely useful tool for testing out new compression theories and formats. The following diagram illustrates the high level progression of each codec in the family.



  year version name features
  2016 EVX-5 Capri artificial intelligence
targeted compression
  2015 EVX-4 Cannes virtual & augmented reality
3D video format support
  2014 EVX-3 Chicago advanced transforms
large macroblock support
  2011 EVX-2 Chennai lossless compression
full rate YCbCr 4:4:4 mode
  2011 EVX-1 Cairo experimental pipeline
video analysis & debugging tool




Source code

The source code to Cannes is not yet available. In the meantime you can check out the source code for Cairo, which serves as the basic framework for Cannes.
