== Abstract ==

The primary goal for this project is to prepare the code base for encoding H.264 video with user defined sample depths. This will involve templating the encoder and migrating existing C code for use with higher sample depths.

As a lot of the code that handles the actual encoding is written in assembly, templating and migrating the encoder won't suffice to enable support for higher sample depths. The secondary goal for the project is therefore to identify new assembly code to be written.
