Theora Git
Xiph.org development projects are available to the public through read-only Git repositories.
Accessing Git at Xiph.org
Access to Xiph.org can be handled basically two ways:
Using the Git client
Once you've installed the Git client, just type
git clone https://git.xiph.org/theora.git
to check out the Theora codebase.
Once you've got the repository checked out, you no longer need to specify this full path; the repository location is stored with the checkout. git pull will sync your local copy with the repository. See the Git manual for additional information on how to use Git.
Using the web interface
To do this, browse the Theora git repositroy.
The source for the legacy VP3 codec for Quicktime and Video for Windows can be obtained from SVN: svn co https://svn.xiph.org/trunk/vp32.
