- This code implements amr-nb audio encoder/decoder through external reference
- code from www.3gpp.org. The licence of the code from 3gpp is unclear so you
- have to download the code separately. Two versions exists: One fixed-point
- and one with floats. For some reason the float-encoder is significant faster
- atleast on a P4 1.5GHz (0.9s instead of 9.9s on a 30s audio clip at MR102).
-
- The fixed-point (TS26.073) can be downloaded from:
- http://www.3gpp.org/ftp/Specs/latest/Rel-5/26_series/26073-510.zip
- Extract the soure into ffmpeg/libavcodec/amr
- To use the float version run "./configure" with "--enable-amr-nb-fixed"
-
- The float version (default) can be downloaded from:
- http://www.3gpp.org/ftp/Specs/latest/Rel-5/26_series/26104-510.zip
- Extract the soure into ffmpeg/libavcodec/amr_float
-
- 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
- info at http://www.3gpp.org/ftp/Specs/html-info/26-series.htm
-
- In the future support for AMR-WB might also be included here.
- Reference code exist in TS26.173 and TS 26.204.

- will return the nest num bits
-
-SHOW_SBITS(name, gb, num)
- will return the nest num bits and do sign extension
-
-SKIP_BITS(name, gb, num)
- will skip over the next num bits
- note, this is equinvalent to SKIP_CACHE; SKIP_COUNTER
-
-SKIP_CACHE(name, gb, num)
- will remove the next num bits from the cache (note SKIP_COUNTER MUST be called before UPDATE_CACHE / CLOSE_READER)

- Full formula for multiplication of 2 integer numbers
- which are represent as high:low words:
- input: value1 = high1:low1
- value2 = high2:low2
- output: value3 = value1*value2
- value3=high3:low3 (on overflow: modulus 2^32 wrap-around)
- this mean that for 0x123456 * 0x123456 correct result is 0x766cb0ce4
- but this algorithm will compute only 0x66cb0ce4
- this limited by 16-bit size of operands
- ---------------------------------

- * For more information about the Interplay MVE format, visit:
- * http://www.pcisys.net/~melanson/codecs/interplay-mve.txt
- * This code is written in such a way that the identifiers match up
- * with the encoding descriptions in the document.
- *
- * This decoder presently only supports a PAL8 output colorspace.
- *
- * An Interplay video frame consists of 2 parts: The decoding map and
- * the video data. A demuxer must load these 2 parts together in a single
- * 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.

- * 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.)
- *

- * 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.

-TODO:
-reduce the time wasted on the mem transfer
-unroll stuff if instructions depend too much on the prior one
-move YScale thing to the end instead of fixing QP
-write a faster and higher quality deblocking filter :)
-make the mainloop more flexible (variable number of blocks at once

- * 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

- The simplest is an interface based on write(): simply write
- full DV frames of data to the device, and they will be transmitted
- as quickly as possible. The FD may be set for non-blocking I/O,
- in which case you can use select() or poll() to wait for output
- buffer space.
-
- To set the DV output parameters (e.g. whether you want NTSC or PAL
- video), use the DV1394_INIT ioctl, passing in the parameters you
- want in a struct dv1394_init.
-
- Example 1:
- To play a raw .DV file: cat foo.DV > /dev/dv1394
- (cat will use write() internally)
-
- Example 2:
- static struct dv1394_init init = {
- 0x63, (broadcast channel)
- 4, (four-frame ringbuffer)
- DV1394_NTSC, (send NTSC video)
- 0, 0 (default empty packet rate)
- }
-
- ioctl(fd, DV1394_INIT, &init);
-
- while(1) {
- read( <a raw DV file>, buf, DV1394_NTSC_FRAME_SIZE );
- write( <the dv1394 FD>, buf, DV1394_NTSC_FRAME_SIZE );
- }
-
- 2)
-
- For more control over buffering, and to avoid unnecessary copies
- of the DV data, you can use the more sophisticated the mmap() interface.
- First, call the DV1394_INIT ioctl to specify your parameters,
- including the number of frames in the ringbuffer. Then, calling mmap()
- on the dv1394 device will give you direct access to the ringbuffer
- from which the DV card reads your frame data.
-
- The ringbuffer is simply one large, contiguous region of memory
- containing two or more frames of packed DV data. Each frame of DV data
- is 120000 bytes (NTSC) or 144000 bytes (PAL).
-
- Fill one or more frames in the ringbuffer, then use the DV1394_SUBMIT_FRAMES
- ioctl to begin I/O. You can use either the DV1394_WAIT_FRAMES ioctl
- or select()/poll() to wait until the frames are transmitted. Next, you'll
- need to call the DV1394_GET_STATUS ioctl to determine which ringbuffer
- frames are clear (ready to be filled with new DV data). Finally, use
- DV1394_SUBMIT_FRAMES again to send the new data to the DV output.
-
-
- Example: here is what a four-frame ringbuffer might look like
- during DV transmission:
-
-
- frame 0 frame 1 frame 2 frame 3
-
- *--------------------------------------*
- | CLEAR | DV data | DV data | CLEAR |
- *--------------------------------------*
- <ACTIVE>
-
- transmission goes in this direction --->>>
-
-
- The DV hardware is currently transmitting the data in frame 1.
- Once frame 1 is finished, it will automatically transmit frame 2.
- (if frame 2 finishes before frame 3 is submitted, the device
- will continue to transmit frame 2, and will increase the dropped_frames
- counter each time it repeats the transmission).
-
-
- If you called DV1394_GET_STATUS at this instant, you would
- receive the following values:
-
- n_frames = 4
- active_frame = 1
- first_clear_frame = 3
- n_clear_frames = 2
-
- At this point, you should write new DV data into frame 3 and optionally
- frame 0. Then call DV1394_SUBMIT_FRAMES to inform the device that
- it may transmit the new frames.
-
- ERROR HANDLING
-
- An error (buffer underflow/overflow or a break in the DV stream due
- to a 1394 bus reset) can be detected by checking the dropped_frames
- field of struct dv1394_status (obtained through the
- DV1394_GET_STATUS ioctl).
-
- The best way to recover from such an error is to re-initialize
- dv1394, either by using the DV1394_INIT ioctl call, or closing the
- file descriptor and opening it again. (note that you must unmap all
- ringbuffer mappings when closing the file descriptor, or else
- dv1394 will still be considered 'in use').
-
- MAIN LOOP
-
- For maximum efficiency and robustness against bus errors, you are
- advised to model the main loop of your application after the
- following pseudo-code example:
-
- (checks of system call return values omitted for brevity; always
- check return values in your code!)
-
- while( frames left ) {
-
- struct pollfd *pfd = ...;
-
- pfd->fd = dv1394_fd;
- pfd->revents = 0;
- pfd->events = POLLOUT | POLLIN; (OUT for transmit, IN for receive)
-
- (add other sources of I/O here)
-
- poll(pfd, 1, -1); (or select(); add a timeout if you want)
-
- if(pfd->revents) {
- struct dv1394_status status;
-
- ioctl(dv1394_fd, DV1394_GET_STATUS, &status);
-
- if(status.dropped_frames > 0) {
- reset_dv1394();
- } else {
- for(int i = 0; i < status.n_clear_frames; i++) {
- copy_DV_frame();
- }
- }
- }
- }
-
- where copy_DV_frame() reads or writes on the dv1394 file descriptor
- (read/write mode) or copies data to/from the mmap ringbuffer and
- then calls ioctl(DV1394_SUBMIT_FRAMES) to notify dv1394 that new
- frames are availble (mmap mode).
-
- reset_dv1394() is called in the event of a buffer
- underflow/overflow or a halt in the DV stream (e.g. due to a 1394
- bus reset). To guarantee recovery from the error, this function
- should close the dv1394 file descriptor (and munmap() all
- ringbuffer mappings, if you are using them), then re-open the
- dv1394 device (and re-map the ringbuffer).

-
-/* Q: What are cip_n and cip_d? */
-
-/*
- A: DV video streams do not utilize 100% of the potential bandwidth offered
- by IEEE 1394 (FireWire). To achieve the correct rate of data transmission,
- DV devices must periodically insert empty packets into the 1394 data stream.
- Typically there is one empty packet per 14-16 data-carrying packets.
-
- Some DV devices will accept a wide range of empty packet rates, while others
- require a precise rate. If the dv1394 driver produces empty packets at
- a rate that your device does not accept, you may see ugly patterns on the
- DV output, or even no output at all.
-
- The default empty packet insertion rate seems to work for many people; if
- your DV output is stable, you can simply ignore this discussion. However,
- we have exposed the empty packet rate as a parameter to support devices that
- do not work with the default rate.
-
- The decision to insert an empty packet is made with a numerator/denominator
- algorithm. Empty packets are produced at an average rate of CIP_N / CIP_D.
- You can alter the empty packet rate by passing non-zero values for cip_n
- and cip_d to the INIT ioctl.

-/*
- * 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.

- * FIXED, Francois Revol, 07/17/2002
- * - ffmpeg has nearly none of the usual QuickTime codecs,
- * although I succesfully dumped raw and mp3 audio tracks off .mov files.
- * Sample QuickTime files with mp3 audio can be found at: http://www.3ivx.com/showcase.html
- * - .mp4 parsing is still hazardous, although the format really is QuickTime with some minor changes
- * (to make .mov parser crash maybe ?), despite what they say in the MPEG FAQ at
- * http://mpeg.telecomitalialab.com/faq.htm
- * - the code is quite ugly... maybe I won't do it recursive next time :-)
