2012-06-11Optimization of AMR NB and WB decoders for MIPSNedeljko Babic
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.

* qatar/master: tests: Refactor rotozoom/videogen common code into a separate file. tests: Mark some file-internal symbols as static. build: Drop leftover .exp pattern from LIBSUFFIXES list. vsrc_buffer: return EAGAIN if no frame is available. WMAL: Shift output samples by the specified number of padding zeroes. WMAL: Restore removed code in mclms_predict() rtpdec_h264: Remove a useless ifdef rtpdec_h264: Remove outdated/useless/incorrect comments rtpdec_h264: Remove useless memory corruption checks rtpdec_h264: Return proper error codes rtpdec_h264: Check the available data length before reading rtpdec_h264: Add input size checks png: check bit depth for PAL8/Y400A pixel formats. ea: check chunk_size for validity. celp filters: Do not read earlier than the start of the 'out' vector.

2009-11-10And on the sixth day, God gave us the <= operand, which makes the loopRonald S. Bultje
"for (i = 1; i < num + 1; i++)" look like "for (i = 1; i <= num; i++)". Programmers worldwide rejoiced and used the operand, e.g. in the thread "[PATCH] remove ugliness in cel_filters.c", and He saw that it was good. Originally committed as revision 20489 to svn://svn.ffmpeg.org/ffmpeg/trunk
2009-08-12Add ff_celp_circ_addf() function to be used for sparse vector circularColin McQuillan
convolution in the upcoming AMR-NB floating point decoder. The function scales and adds a vector, that is lagged by some offset, to another vector with the same number of elements.
