1 | Library: libcook | ||
2 | Imported by : Mohamed Tarek | ||
3 | |||
4 | These files comprise a rm parser and a cook decoder based on the decoder | ||
5 | from ffmpeg. | ||
6 | |||
7 | LICENSING INFORMATION | ||
8 | |||
9 | ffmpeg is licensed under the Lesser GNU General Public License and the | ||
10 | file cook.c is Copyright 2003 Sascha Sommer and 2005 Benjamin Larsson. | ||
11 | |||
12 | IMPORT DETAILS | ||
13 | |||
14 | The decoder is based on ffmpeg-svn r18079. | ||
15 | |||
16 | CONVERSION TO FIXED-POINT | ||
17 | |||
18 | A patch from ffmpeg's mailing list was used to convert the decoder to | ||
19 | use fixed-point arithmetic. The patch was done by Ian Braithwaite, and | ||
20 | discussed here : | ||
21 | |||
22 | http://thread.gmane.org/gmane.comp.video.ffmpeg.devel/46024 | ||
23 | |||
24 | The patch is a bit dated (2007) so the modifications to cook.c had to | ||
25 | be done manually. The patch was also applied to cookdata.h and was | ||
26 | used to create cookdata_fixpoint.h, cook_fixpoint.h and | ||
27 | cook_fixp_mdct.h. | ||
28 | |||
29 | cook_fixp_mdct.h and parts from cookdata_fixpoint.h were dropped and | ||
30 | rockbox's mdct library is now used in both the test program and the | ||
31 | real codec. | ||
32 | |||
33 | Note : Only parts of the patch were committed to ffmpeg's repository. | ||
34 | |||
35 | TESTING | ||
36 | |||
37 | The test program should compile in any Unix-like environment using the | ||
38 | command "make -f Makefile.test". | ||
39 | |||
40 | For ARM targets add -DCPU_ARM to CFLAGS in Makefile.test to make use of | ||
41 | the asm ARM optimisations in rockbox's mdct library. | ||
42 | |||
43 | For Big-endian targets, change -D"ROCKBOX_LITTLE_ENDIAN=1" | ||
44 | to -D"ROCKBOX_BIG_ENDIAN=1" in Makefile.test. | ||
45 | |||
46 | Running "./cooktest file.rm" will decode the audio data to a WAV file | ||
47 | called "output.wav" in the current directory. | ||

24 | * @file cook.c | ||
25 | * Cook compatible decoder. Bastardization of the G.722.1 standard. | ||
26 | * This decoder handles RealNetworks, RealAudio G2 data. | ||
27 | * Cook is identified by the codec name cook in RM files. | ||
28 | * | ||
29 | * To use this decoder, a calling application must supply the extradata | ||
30 | * bytes provided from the RM container; 8+ bytes for mono streams and | ||
31 | * 16+ for stereo streams (maybe more). | ||
32 | * | ||
33 | * Codec technicalities (all this assume a buffer length of 1024): | ||
34 | * Cook works with several different techniques to achieve its compression. | ||
35 | * In the timedomain the buffer is divided into 8 pieces and quantized. If | ||
36 | * two neighboring pieces have different quantization index a smooth | ||
37 | * quantization curve is used to get a smooth overlap between the different | ||
38 | * pieces. | ||
39 | * To get to the transformdomain Cook uses a modulated lapped transform. | ||
40 | * The transform domain has 50 subbands with 20 elements each. This | ||
41 | * means only a maximum of 50*20=1000 coefficients are used out of the 1024 | ||
42 | * available. | ||
