Research on usefulness of the EXA extension for Video playback

[sunweaver]

NAME
exa − new 2D acceleration architecture for X.Org

DESCRIPTION
EXA provides a simple API for video drivers to implement for 2D acceleration. It is a module loaded by drivers, and is not intended to be loaded on its own. See your driver’s manual page for how to enable EXA.

The EXA architecture is designed to make accelerating the Render extension simple and efficient, and results in various performance tradeoffs compared to XAA. Some xorg.conf options are available for debugging performance issues or driver rendering problems. They are not intended for general use.

Currently the X-Video extension is kind of useless since it only reports this:

X-Video Extension version 2.2
