Are there any plans to add the Dirac open source video codec to VLC ?

The latest version of the Dirac open source video codec includes :
- Added C interface for the decoder application to allow interfacing to player software. Refer to the api documentation in dirac_parser.h.

Dirac sourceforge project

Dirac is a general-purpose video codec aimed at resolutions from QCIF (180x144) to HDTV (1920x1080) progressive or interlaced. It uses wavelets, motion compensation and arithmetic coding and aims to be competitive with other state of the art codecs.

Last time I looked at dirac documentation the bitstream format was not nearly frozen, they didn't even know yet how to mux dirac into container formats. Untill this is nearing completion I don't think there is any chance of it getting into vlc.

Summary: Dirac-0.4.0 released
This version is a major release and contains many improvements over version 0.3.x.

The main features are

- Added constant quality encoding interface using PSNR as the quality measure, and using multi-pass frame coding

- Implemented unique frame headers to facilitate bit-stream parsing. The document describing the syntax of Dirac bitstream v0.1 is included in the doc directory.

- Added C interface for the decoder application to allow interfacing to player software. Refer to the api documentation in dirac_parser.h.

- Added Intra-frame insertion and cut detection

- Added instrumentation output from encoder and an instrumentation display tool for visualising encoder decisions to help with algorithmic development

- Added a unit testing framework based on cppunit for testing classes

- Added feature to encode only a section of input video rather than the whole sequence

- Tweaked motion estimation parameters to improve performance, mostly for higher-res pictures

- Fixed bug with vertical block separation always being set to 8 pixels

- Fixed bug 1008694 (Out-of-tree building fails)

- Fixed header and pkconfig installation

- Cleansed and refactored numerous code files to add comments, improve readability and modularity
