+ * ALAC (Apple Lossless Audio Codec) decoder
+ * @author 2005 David Hammerton
+ *
+ * For more information on the ALAC format, visit:
+ *  http://crazney.net/programs/itunes/alac.html
+ *
+ * Note: This decoder expects a 36- (0x24-)byte QuickTime atom to be
+ * passed through the extradata[_size] fields. This atom is tacked onto
+ * the end of an 'alac' stsd atom and has the following format:
+ *  bytes 0-3   atom size (0x24), big-endian
+ *  bytes 4-7   atom type ('alac', not the 'alac' tag from start of stsd)
+ *  bytes 8-35  data bytes needed by decoder
+ *
+ * Extradata:
+ * 32bit  size
+ * 32bit  tag (=alac)
+ * 32bit  zero?
+ * 32bit  max sample per frame
+ *  8bit  ?? (zero?)
+ *  8bit  sample size
+ *  8bit  history mult
+ *  8bit  initial history
+ *  8bit  kmodifier
+ *  8bit  channels?
+ * 16bit  ??
+ * 32bit  max coded frame size
+ * 32bit  bitrate?
+ * 32bit  samplerate

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

+ Generation of Lt Rt
+
+In the case when the playback system has analog or digital surround multi-channel capability, a down matrix from 5, 4, or 3 channel to Lt Rt may be desirable. In the case when the number of decoded audio channels exceeds 5, 4 or 3 respectively a first stage down mix to 5, 4 or 3 chs should be used as described above.
+
+The down matrixing equations for 5-channel source audio to a two-channel Lt Rt playback system are given by:
+
+Left left+0.7*center-0.7*(lt surround+rt surround)
+
+Right=right+0.7*center+0.7*(lt surround+rt surround)
+
+Embedded mixing to 2-channel
+
+One concern arising from the proliferation of multi-channel audio systems is that most home systems presently have only two channel playback capability. To accommodate this a fixed 2-channel down matrix processes is commonly used following the multi-channel decoding stage. However, for music only applications the image quality etc. of the down matrixed signal may not match that of an equivalent stereo recording found on CD.
+
+The concept of embedded mixing is to allow the producer to dynamically specify the matrixing coefficients within the audio frame itself. In this way the stereo down mix at the decoder may be better matched to a 2-channel playback environment.
+
+CHS*2, 7-bit down mix indexes (MCOEFFS) are transmitted along with the multi-channel audio once in every frame. The indexes are converted to attenuation factors using a 7 bit LUT. The 2-ch down mix equations are as follows,
+
+Left Ch=sum (MCOEFF[n]*Ch[n]) for n=1, CHS
+
+Right Ch sum (MCOEFF[n+CHS]*Ch[n]) for n=1, CHS
+
+where Ch(n) represents the subband samples in the (n)th audio channel.

+ * Assorted DPCM (differential pulse code modulation) audio codecs

+ * Xan DPCM decoder by Mario Brito (mbrito@student.dei.uc.pt)
+ * for more information on the specific data formats, visit:
+ *   http://www.pcisys.net/~melanson/codecs/simpleaudio.html
+ * SOL DPCMs implemented by Konstantin Shishkov
+ *
+ * Note about using the Xan DPCM decoder: Xan DPCM is used in AVI files
+ * found in the Wing Commander IV computer game. These AVI files contain
+ * WAVEFORMAT headers which report the audio format as 0x01: raw PCM.
+ * Clearly incorrect. To detect Xan DPCM, you will probably have to
+ * special-case your AVI demuxer to use Xan DPCM if the file uses 'Xxan'
+ * (Xan video) for its video codec. Alternately, such AVI files also contain
+ * the fourcc 'Axan' in the 'auds' chunk of the AVI header.

+ * First version by Francois Revol revol@free.fr
+ *
+ * Features and limitations:
+ * - currently no compression is performed,
+ *   in fact the size of the data is 9/8 the size of the image in 8bpp
+ * - uses only a global standard palette
+ * - tested with IE 5.0, Opera for BeOS, NetPositive (BeOS), and Mozilla (BeOS).
+ *
+ * Reference documents:
+ * http://www.goice.co.jp/member/mo/formats/gif.html
+ * http://astronomy.swin.edu.au/pbourke/dataformats/gif/
+ * http://www.dcs.ed.ac.uk/home/mxr/gfx/2d/GIF89a.txt
+ *
+ * this url claims to have an LZW algorithm not covered by Unisys patent:
+ * http://www.msg.net/utility/whirlgif/gifencod.html
+ * could help reduce the size of the files _a lot_...
+ * some sites mentions an RLE type compression also.

+ * Id Quake II Cin Video Decoder by Dr. Tim Ferguson
+ * For more information about the Id CIN format, visit:
+ *   http://www.csse.monash.edu.au/~timf/
+ *
+ * This video decoder outputs PAL8 colorspace data. Interacting with this
+ * decoder is a little involved. During initialization, the demuxer must
+ * transmit the 65536-byte Huffman table(s) to the decoder via extradata.
+ * Then, whenever a palette change is encountered while demuxing the file,
+ * the demuxer must use the same extradata space to transmit an
+ * AVPaletteControl structure.
+ *
+ * Id CIN video is purely Huffman-coded, intraframe-only codec. It achieves
+ * a little more compression by exploiting the fact that adjacent pixels
+ * tend to be similar.
+ *
+ * Note that this decoder could use ffmpeg's optimized VLC facilities
+ * rather than naive, tree-based Huffman decoding. However, there are 256
+ * Huffman tables. Plus, the VLC bit coding order is right -> left instead
+ * or left -> right, so all of the bits would have to be reversed. Further,
+ * the original Quake II implementation likely used a similar naive
+ * decoding algorithm and it worked fine on much lower spec machines.

+ * This code is written in such a way that the identifiers match up

+ * This decoder presently only supports a PAL8 output colorspace.
+ *
+ * An Interplay video frame consists of 2 parts: The decoding map and

+ * buffer before sending it through the stream to this decoder.

+ * This file contains a fast, not so accurate integer implementation of the
+ * forward DCT (Discrete Cosine Transform).
+ *
+ * A 2-D DCT can be done by 1-D DCT on each row followed by 1-D DCT
+ * on each column.  Direct algorithms are also available, but they are
+ * much more complex and seem not to be any faster when reduced to code.
+ *
+ * This implementation is based on Arai, Agui, and Nakajima's algorithm for
+ * scaled DCT.  Their original paper (Trans. IEICE E-71(11):1095) is in
+ * Japanese, but the algorithm is described in the Pennebaker & Mitchell
+ * JPEG textbook (see REFERENCES section in file README).  The following code
+ * is based directly on figure 4-8 in P&M.
+ * While an 8-point DCT cannot be done in less than 11 multiplies, it is
+ * possible to arrange the computation so that many of the multiplies are
+ * simple scalings of the final outputs.  These multiplies can then be
+ * folded into the multiplications or divisions by the JPEG quantization
+ * table entries.  The AA&N method leaves only 5 multiplies and 29 adds
+ * to be done in the DCT itself.
+ * The primary disadvantage of this method is that with fixed-point math,
+ * accuracy is lost due to imprecise representation of the scaled
+ * quantization values.  The smaller the quantization table entry, the less
+ * precise the scaled value, so this implementation does worse with high-
+ * quality-setting files than with low-quality ones.

+ * This file contains a slow-but-accurate integer implementation of the
+ * forward DCT (Discrete Cosine Transform).
+ *
+ * A 2-D DCT can be done by 1-D DCT on each row followed by 1-D DCT
+ * on each column.  Direct algorithms are also available, but they are
+ * much more complex and seem not to be any faster when reduced to code.
+ *
+ * This implementation is based on an algorithm described in
+ *   C. Loeffler, A. Ligtenberg and G. Moschytz, "Practical Fast 1-D DCT
+ *   Algorithms with 11 Multiplications", Proc. Int'l. Conf. on Acoustics,
+ *   Speech, and Signal Processing 1989 (ICASSP '89), pp. 988-991.
+ * The primary algorithm described there uses 11 multiplies and 29 adds.
+ * We use their alternate method with 12 multiplies and 32 adds.
+ * The advantage of this method is that no data path contains more than one
+ * multiplication; this allows a very simple and accurate implementation in
+ * scaled fixed-point arithmetic, with a minimal number of shifts.

+ * The poop on this scaling stuff is as follows:
+ *
+ * Each 1-D DCT step produces outputs which are a factor of sqrt(N)
+ * larger than the true DCT outputs.  The final outputs are therefore
+ * a factor of N larger than desired; since N=8 this can be cured by
+ * a simple right shift at the end of the algorithm.  The advantage of
+ * this arrangement is that we save two multiplications per 1-D DCT,
+ * because the y0 and y4 outputs need not be divided by sqrt(N).
+ * In the IJG code, this factor of 8 is removed by the quantization step
+ * (in jcdctmgr.c), NOT in this module.
+ *
+ * We have to do addition and subtraction of the integer inputs, which
+ * is no problem, and multiplication by fractional constants, which is
+ * a problem to do in integer arithmetic.  We multiply all the constants
+ * by CONST_SCALE and convert them to integer constants (thus retaining
+ * CONST_BITS bits of precision in the constants).  After doing a
+ * multiplication we have to divide the product by CONST_SCALE, with proper
+ * rounding, to produce the correct output.  This division can be done
+ * cheaply as a right shift of CONST_BITS bits.  We postpone shifting
+ * as long as possible so that partial sums can be added together with
+ * full fractional precision.
+ *
+ * The outputs of the first pass are scaled up by PASS1_BITS bits so that
+ * they are represented to better-than-integral precision.  These outputs
+ * require BITS_IN_JSAMPLE + PASS1_BITS + 3 bits; this fits in a 16-bit word
+ * with the recommended scaling.  (For 12-bit sample data, the intermediate
+ * array is int32_t anyway.)
+ *
+ * To avoid overflow of the 32-bit intermediate results in pass 2, we must
+ * have BITS_IN_JSAMPLE + CONST_BITS + PASS1_BITS <= 26.  Error analysis
+ * shows that the values given below are the most effective.

+ * This file contains the basic inverse-DCT transformation subroutine.
+ *
+ * This implementation is based on an algorithm described in
+ *   C. Loeffler, A. Ligtenberg and G. Moschytz, "Practical Fast 1-D DCT
+ *   Algorithms with 11 Multiplications", Proc. Int'l. Conf. on Acoustics,
+ *   Speech, and Signal Processing 1989 (ICASSP '89), pp. 988-991.
+ * The primary algorithm described there uses 11 multiplies and 29 adds.
+ * We use their alternate method with 12 multiplies and 32 adds.
+ * The advantage of this method is that no data path contains more than one
+ * multiplication; this allows a very simple and accurate implementation in
+ * scaled fixed-point arithmetic, with a minimal number of shifts.
+ *
+ * I've made lots of modifications to attempt to take advantage of the
+ * sparse nature of the DCT matrices we're getting.  Although the logic
+ * is cumbersome, it's straightforward and the resulting code is much
+ * faster.
+ *
+ * A better way to do this would be to pass in the DCT block as a sparse
+ * matrix, perhaps with the difference cases encoded.

+ * A 2-D IDCT can be done by 1-D IDCT on each row followed by 1-D IDCT
+ * on each column.  Direct algorithms are also available, but they are
+ * much more complex and seem not to be any faster when reduced to code.
+ *
+ * The poop on this scaling stuff is as follows:
+ *
+ * Each 1-D IDCT step produces outputs which are a factor of sqrt(N)
+ * larger than the true IDCT outputs.  The final outputs are therefore
+ * a factor of N larger than desired; since N=8 this can be cured by
+ * a simple right shift at the end of the algorithm.  The advantage of
+ * this arrangement is that we save two multiplications per 1-D IDCT,
+ * because the y0 and y4 inputs need not be divided by sqrt(N).
+ *
+ * We have to do addition and subtraction of the integer inputs, which
+ * is no problem, and multiplication by fractional constants, which is
+ * a problem to do in integer arithmetic.  We multiply all the constants
+ * by CONST_SCALE and convert them to integer constants (thus retaining
+ * CONST_BITS bits of precision in the constants).  After doing a
+ * multiplication we have to divide the product by CONST_SCALE, with proper
+ * rounding, to produce the correct output.  This division can be done
+ * cheaply as a right shift of CONST_BITS bits.  We postpone shifting
+ * as long as possible so that partial sums can be added together with
+ * full fractional precision.
+ *
+ * The outputs of the first pass are scaled up by PASS1_BITS bits so that
+ * they are represented to better-than-integral precision.  These outputs
+ * require BITS_IN_JSAMPLE + PASS1_BITS + 3 bits; this fits in a 16-bit word
+ * with the recommended scaling.  (To scale up 12-bit sample data further, an
+ * intermediate int32 array would be needed.)
+ *
+ * To avoid overflow of the 32-bit intermediate results in pass 2, we must
+ * have BITS_IN_JSAMPLE + CONST_BITS + PASS1_BITS <= 26.  Error analysis
+ * shows that the values given below are the most effective.

+ /** @file
+ * Adaptive Multi-Rate (AMR) Audio decoder stub.
+ *
+ * This code implements both an AMR-NarrowBand (AMR-NB) and an AMR-WideBand
+ * (AMR-WB) audio encoder/decoder through external reference code from
+ * http://www.3gpp.org/. The license of the code from 3gpp is unclear so you
+ * have to download the code separately. Two versions exists: One fixed-point
+ * and one floating-point. For some reason the float encoder is significantly
+ * faster at least on a P4 1.5GHz (0.9s instead of 9.9s on a 30s audio clip
+ * at MR102). Both float and fixed point are supported for AMR-NB, but only
+ * float for AMR-WB.
+ *
+ * \section AMR-NB
+ *
+ * \subsection Float
+ * The float version (default) can be downloaded from:
+ * http://www.3gpp.org/ftp/Specs/archive/26_series/26.104/26104-610.zip
+ *
+ * \subsection Fixed-point
+ * The fixed-point (TS26.073) can be downloaded from:
+ * http://www.3gpp.org/ftp/Specs/archive/26_series/26.073/26073-600.zip
+ *
+ * \subsection Specification
+ * The specification for AMR-NB can be found in TS 26.071
+ * (http://www.3gpp.org/ftp/Specs/html-info/26071.htm) and some other

+  This is due to the use of the 'dcbz' instruction.
+  It simply clear to zero a single cache line,

+  It's absurd, but it's fast...
+
+  update 24/06/2003 : Apple released yesterday the G5,
+  with a PPC970. cache line size : 128 bytes. Oups.
+  The semantic of dcbz was changed, it always clear
+  32 bytes. so the function below will work, but will
+  be slow. So I fixed check_dcbz_effect to use dcbzl,
+  which is defined to clear a cache line (as dcbz before).
+  So we still can distinguish, and use dcbz (32 bytes)
+  or dcbzl (one cache line) as required.

+ * QT RLE Video Decoder by Mike Melanson (melanson@pcisys.net)
+ * For more information about the QT RLE format, visit:
+ *   http://www.pcisys.net/~melanson/codecs/
+ *
+ * The QT RLE decoder has seven modes of operation:
+ * 1, 2, 4, 8, 16, 24, and 32 bits per pixel. For modes 1, 2, 4, and 8
+ * the decoder outputs PAL8 colorspace data. 16-bit data yields RGB555
+ * data. 24-bit data is RGB24 and 32-bit data is RGB32.

+/* You may be asking why I hard-code the instruction opcodes and don't
+ * use the normal VIS assembler mnenomics for the VIS instructions.
+ *
+ * The reason is that Sun, in their infinite wisdom, decided that a binary
+ * using a VIS instruction will cause it to be marked (in the ELF headers)
+ * as doing so, and this prevents the OS from loading such binaries if the
+ * current cpu doesn't have VIS.  There is no way to easily override this
+ * behavior of the assembler that I am aware of.
+ *
+ * This totally defeats what libmpeg2 is trying to do which is allow a
+ * single binary to be created, and then detect the availability of VIS
+ * at runtime.
+ *
+ * I'm not saying that tainting the binary by default is bad, rather I'm
+ * saying that not providing a way to override this easily unnecessarily
+ * ties people's hands.
+ *
+ * Thus, we do the opcode encoding by hand and output 32-bit words in
+ * the assembler to keep the binary from becoming tainted.

+ * How to use this decoder:
+ * SVQ3 data is transported within Apple Quicktime files. Quicktime files
+ * have stsd atoms to describe media trak properties. A stsd atom for a
+ * video trak contains 1 or more ImageDescription atoms. These atoms begin
+ * with the 4-byte length of the atom followed by the codec fourcc. Some
+ * decoders need information in this atom to operate correctly. Such
+ * is the case with SVQ3. In order to get the best use out of this decoder,
+ * the calling app must make the SVQ3 ImageDescription atom available
+ * via the AVCodecContext's extradata[_size] field:
+ *
+ * AVCodecContext.extradata = pointer to ImageDescription, first characters
+ * are expected to be 'S', 'V', 'Q', and '3', NOT the 4-byte atom length
+ * AVCodecContext.extradata_size = size of ImageDescription atom memory
+ * buffer (which will be the same as the ImageDescription atom size field
+ * from the QT file, minus 4 bytes since the length is missing)
+ *
+ * You will know you have these parameters passed correctly when the decoder
+ * correctly decodes this file:
+ *  ftp://ftp.mplayerhq.hu/MPlayer/samples/V-codecs/SVQ3/Vertical400kbit.sorenson3.mov

+ * VQA Video Decoder by Mike Melanson (melanson@pcisys.net)
+ * For more information about the VQA format, visit:
+ *   http://wiki.multimedia.cx/index.php?title=VQA
+ *
+ * The VQA video decoder outputs PAL8 or RGB555 colorspace data, depending
+ * on the type of data in the file.
+ *
+ * This decoder needs the 42-byte VQHD header from the beginning
+ * of the VQA file passed through the extradata field. The VQHD header
+ * is laid out as:
+ *
+ *   bytes 0-3   chunk fourcc: 'VQHD'
+ *   bytes 4-7   chunk size in big-endian format, should be 0x0000002A
+ *   bytes 8-49  VQHD chunk data
+ *
+ * Bytes 8-49 are what this decoder expects to see.
+ *
+ * Briefly, VQA is a vector quantized animation format that operates in a
+ * VGA palettized colorspace. It operates on pixel vectors (blocks)
+ * of either 4x2 or 4x4 in size. Compressed VQA chunks can contain vector
+ * codebooks, palette information, and code maps for rendering vectors onto
+ * frames. Any of these components can also be compressed with a run-length
+ * encoding (RLE) algorithm commonly referred to as "format80".
+ *
+ * VQA takes a novel approach to rate control. Each group of n frames
+ * (usually, n = 8) relies on a different vector codebook. Rather than
+ * transporting an entire codebook every 8th frame, the new codebook is
+ * broken up into 8 pieces and sent along with the compressed video chunks
+ * for each of the 8 frames preceding the 8 frames which require the
+ * codebook. A full codebook is also sent on the very first frame of a
+ * file. This is an interesting technique, although it makes random file
+ * seeking difficult despite the fact that the frames are all intracoded.
+ *
+ * V1,2 VQA uses 12-bit codebook indices. If the 12-bit indices were
+ * packed into bytes and then RLE compressed, bytewise, the results would
+ * be poor. That is why the coding method divides each index into 2 parts,
+ * the top 4 bits and the bottom 8 bits, then RL encodes the 4-bit pieces
+ * together and the 8-bit pieces together. If most of the vectors are
+ * clustered into one group of 256 vectors, most of the 4-bit index pieces
+ * should be the same.
