Mans Rullgard	f0c07be649	celp_math: rename ff_log2 to ff_log2_q15 This name is more descriptive as the function returns a fixed-point value with 15 fraction bits. Signed-off-by: Mans Rullgard <mans@mansr.com>	12 years ago
Diego Biurrun	dafcbfe443	celp_math: Replace duplicate ff_dot_productf() by ff_scalarproduct_c()	13 years ago
Diego Biurrun	5549854335	celp_math: Move ff_cos() to the only place it is used	13 years ago
Nedeljko Babic	3827a86eac	Optimization of AMR NB and WB decoders for MIPS AMR NB and WB decoders are optimized for MIPS architecture. Appropriate Makefiles are changed accordingly. Cnfigure script is changed in order to support optimizations. Optimizations are enabled by default when compiling is done for mips architecture. Appropriate cflags are automatically set. Support for several mips CPUs is added in configure script. New ffmpeg options are added for disabling optimizations. The FFMPEG option --disable-mipsfpu disables MIPS floating point optimizations. The FFMPEG option --disable-mips32r2 disables MIPS32R2 optimizations. The FFMPEG option --disable-mipsdspr1 disables MIPS DSP ASE R1 optimizations. The FFMPEG option --disable-mipsdspr2 disables MIPS DSP ASE R2 optimizations.

Stefano Sabatini	987903826b	Globally rename the header inclusion guard names. Consistently apply this rule: the guard name is obtained from the filename by stripping the leading "lib", converting '/' and '.' to '_' and uppercasing the resulting name. Guard names in the root directory have to be prefixed by "FFMPEG_". Originally committed as revision 15120 to svn://svn.ffmpeg.org/ffmpeg/trunk	17 years ago
