= Vorbis rehuff code =

Rehuff was a tool to losslessly compress Vorbis files. Latest rehuff version (see [http://lists.xiph.org/pipermail/vorbis-dev/2006-August/018522.html rehuff status]), had some limits:
* it's not free software;
* it has a bug causing the rehuffed file can't correctly seek;
* it works only with stereo files.

= Theora rehuff code =
tterribe, on 2007-05-02 in [http://lists.xiph.org/pipermail/commits/2007-May/010884.html SVN revision r12913], commited a new rehuff code, which works on Theora streams. The code is included in the [http://svn.xiph.org/trunk/theora-exp/ svn trunk of theora-exp].

== How to get it working ==

* Get the latest theora-exp:
svn co http://svn.xiph.org/trunk/theora-exp/
* Compile rehuff code:
cd theora-exp/unix
make rehuff
* Use it:
./rehuff [-s <statsout.txt> ] <infile.ogg> <outfile.ogg>

== A try on r12913 version ==

* Current version does not rehuff ogg vorbis files.
* It gives a ''Segmentation fault'' when not specifiing <outfile.ogg>.
* Rehuffing is pretty fast.
* Rehuffed files, decoded with dump_video, are the same of the original files.
* Rehuffed files are about 0,4-1,5% smaller than original files.
* However, when played with QuickTime Player, using [http://xiph.org/quicktime/ QuickTime Components], some rehuffed file seem more ''blurred'' at the beginning (e.g., look at the text ''A New Computer'' on the rehuff of this file http://www.polycrystal.org/lego/movies/A_New_Computer--med.ogg). This is not reproducible on VLC, so this may be only a problem of QuickTime Components.
