Dirac Encoder AND Decoder

Summer of Code - Dirac Encoder AND Decoder status page

This page is meant to track the progress of dirac implementation in ffmpeg. It will be updated from time to time, for further inquiries contact lu_zero on irc or follow the ffmpeg-soc mailing list.

- Mentor : lu_zero

- Student : Marco Gerards

Phase 1: Learning - (in which mess you had thrown yourself this summer)

This first phase will just help understanding the topic and watching what's already there, no point in reinventing a wheel if there are already some round you can use.

Expected results: getting a better grasp on what's going on, prepare a cluebat just in case the student is faster than the mentor...

Specifications at dirac site: http://dirac.sourceforge.net/DiracSpec1.0.0_pre8.pdf

Misc wavelet theory : http://www.amara.com/current/wavelet.html | http://www.wavelet.org/

Dirac implementations : C++ reference code | C gstreamer implementation

Wavelets implementations: liboil (dirac's, jpeg2k's) | ffmpeg's snow (modified 97, 53)

Phase 2: Implementing the foundation - (of your salvation or your despair)

Decoder implementation starts

Expected results: Start working on the code and refine the knowledge gathered (asking about unclear point in the spec and so on)

ARCHIVED

Phase 3: Building upon it - (your madhouse)

Decoder is fully implemented

Encoder is getting in shape (no quantization, encoded files work with ffdirac decoder but not the reference one)

Expected results: Getting the decoder working
