adf3f09251 Move bitstream.[ch] to codecs/lib/ffmpeg_bitstream.[ch] to avoid duplicate copies across codecs.

2402aecbb5 remove duplicates of bswap.h from libwma, libcook and libatrac. Create codecs/lib/ffmpeg_bswap.h and use it instead.

a8d1cfdec8 Approx 10% speedup in cook on files tested: Remove some inner loops in favour of memcpy/memset/vect_add calls; remove multiplication from index arithmetic in loops in favour of pointer arithmetic; make use of the MULT31, MULT31_SHIFT15 and CLIP_TO_15 implementations from codelib instead of having their own implementations in cook

b957f7214b Rearrange the MDCT library lookup tables so that codecs can access them. Access them in cook. Remove old cook trig tables. Replace old 32x16 bit fixed point multiply code with faster ASM ARM/Coldfire versions using full 32 bit precision. Improves performance signficantly on PP5024 (~200% realtime for a 64k file) while saving a lot of memory and improving accuracy.

95fa7f6a2e Move the code segment that corrects the value of (number of packets) to 
the parser. This is strictly parser-related and main.c shouldn't have to 
deal with it.

than a file descriptor, to make the decoding process as much similar 
as to how it should be in rockbox.

49ba646d57 -Remove all dynamic allocations, hence remove cook_decode_close() which was basically 
needed for freeing allocated memory.
-Remove any ffmpeg-specific attributes (av_const,av_always_inline .. etc.).
-Move some math functions to cook_fixpoint.h - libavutil/common.h is no longer 
needed.
-Remove libavutil/mem.[c/h], libavutil/common.h and libavutil/internal.h.
-Fix a warning in cookdata_fixpoint.h.

remove the latter.

0cb3ad58b3 -Took cook_random() from an old cook.c revision [6 mar 2007], which is a 
simple RNG, to eliminate the need for lfg.c/h.

more common form of my name in docs/COMMITTERS.

67695617a1 The first part of Mohamed Tarek's Google Summer of Code work to implement RealAudio support in Rockbox. This is a self-contained Cook decoder using the original ffmpeg (still floating point) decoder and a new RM parser started by me in 2008 and continued by MT over the past few months. This is the equivalent of libcook.patch1 from FS#10182, but with further cleaning by both MT and me to minimise the differences to the original ffmpeg files. See README.rockbox for more details.
