Author: darkshikari Date: Fri Dec 19 14:45:13 2008 New Revision: 16239 Log: Port x264 deblocking code to libavcodec. This includes SSE2 luma deblocking code and both MMXEXT and SSE2 luma intra deblocking code for H.264 decoding. This assembly is available under --enable-gpl and speeds decoding of Cathedral by 7%.
