Author: Mans Rullgard <[email protected]> Committer: Mans Rullgard <[email protected]> Date: Fri Jun 22 18:52:27 2012 +0100 h264: use asm cabac reader under a generic condition This removes a dependency on implementation details from generic code and allows easy addition of the equivalent optimisation for other architectures than x86.
