Michael Niedermayer	05d3fd44d7	Integrate get_te0_golomb() calls into the code, this allows some checks to be avoided and the function is pretty small. 3% speedup, though this is probably due to changed inlining and not directly this change. Originally committed as revision 16301 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Michael Niedermayer	9963b332d1	Use get_ue_golomb_31() where possible, almost all are just in headers though. Originally committed as revision 16300 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Michael Niedermayer	2f2893ce9b	indent Originally committed as revision 16296 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
Michael Niedermayer	d42fc4a8ca	Use the new VLC table for the first non trailing coeff too. Sadly only 5 cycles faster here on pentium dual. So maybe the complexity is not worth it and this should be reverted ... Originally committed as revision 16295 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago

Diego Biurrun	a6493a8fbd	Rename libavcodec/i386/ --> libavcodec/x86/. It contains optimizations that are not specific to i386 and libavutil uses this naming scheme already. Originally committed as revision 16270 to svn://svn.ffmpeg.org/ffmpeg/trunk	16 years ago
