* Use parsers for RealVideo 3/4 to determine correct PTSKostya Shishkov2011-08-17

* bink: make IDCT take 32-bit inputKostya Shishkov2011-07-27
| | | | | | | | | | | Since IDCT transforming 32-bit input to 8-bit output is unusual and unpractical for most codecs, move Bink IDCT into separate context. Get rid of an additional permutation table while at it since SIMD support for Bink IDCT is unlikely to be implemented in foreseeable future. Quantisation tables also have to change type to signed for proper dequantisation of DCT coefficients. Signed-off-by: Mans Rullgard <mans@mansr.com>
* add Flash Screen Video 2 decoderKostya Shishkov2011-07-22
| | | | Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
* Remove snow/dwt test programMans Rullgard2011-07-20
| | | | | | | This test program so full of programming errors it is impossible to make sense of it. Signed-off-by: Mans Rullgard <mans@mansr.com>
* eac3enc: use frame exponent strategy when applicable.Justin Ruggles2011-07-19
| | | | | | | This checks if the set of selected exponent strategies for all blocks in a channel are in the frame exponent strategy table, and if so, writes the table index instead of each strategy. This saves up to 7 bits per channel per frame, so the overall effect on quality is small.
* cosmetics: rename eac3dec_data.c/h to eac3_data.c/h since the tables will alsoJustin Ruggles2011-07-19
| | | | be used in the E-AC-3 encoder.
* mp3enc: write a xing frame containing number of frames in the fileAnton Khirnov2011-07-08

* build: include sub-makefiles using full path instead of symlinksMans Rullgard2011-06-28
| | | | Signed-off-by: Mans Rullgard <mans@mansr.com>
* build: Remove redundant config.mak includes from subdirectory Makefiles.Diego Biurrun2011-06-25
| | | | | Calling Make from subdirectories is not supported and config.mak has multiple inclusion guards anyway, so the top-level include is enough.
* ac3enc: split templated float vs. fixed functions into a separate file.Justin Ruggles2011-06-13
| | | | | Function pointers are used for templated functions instead of needlessly duplicating many functions.
* rtpenc: MP4A-LATM payload supportJuan Carlos Rodriguez2011-06-10
| | | | | | | This is enabled with an AVOption on the RTP muxer. The SDP generator looks for a latm flag in the rtpflags field. Signed-off-by: Martin Storsjö <martin@martin.st>
* Move E-AC-3 encoder functions to a separate eac3enc.c file.Justin Ruggles2011-06-07
|
* Skip tableprint.h during 'make checkheaders'.Diego Biurrun2011-06-05
| | | | It is only used on the host and may not compile on the target.
* Skip generated table headers during 'make checkheaders'.Diego Biurrun2011-06-05
|
* Fix build of eval-test programMans Rullgard2011-06-05
| | | | | | eval.c has moved to libavutil, move the TESTPROGS entry too. Signed-off-by: Mans Rullgard <mans@mansr.com>
* Skip headers not designed to work standalone during 'make checkheaders'.Diego Biurrun2011-06-04
|
* ac3enc: add support for E-AC-3 encoding.Justin Ruggles2011-05-27
| | | | | This adds basic stream format support and allows for arbitrary bit rates rather than just those supported in AC-3.
* lavc: remove msmpeg4v1 encoder.Anton Khirnov2011-05-24
| | | | | | The encoder has never produced files that could be decoded with any software and there should be no reason to create such files anyway.
* Rename costablegen.c ---> cos_tablegen.c.Diego Biurrun2011-05-19
| | | | | | This is consistent with how all other table generation programs are named. Moreover this ensures that the cos table generation program is correctly deleted when cleaning the tree.
* Collapse tableprint.c into tableprint.h.Diego Biurrun2011-05-19
| | | | | tableprint.c serves little purpose on its own and removing it allows building the table generator programs with the normal HOSTPROGS Makefile rules.
* Simplify trig table rulesMans Rullgard2011-05-19
| | | | | | | | This collapses the make rules for the trig tables into a pattern rule. Based on a patch by Diego, modified to avoid using fragile make constructs and allow future addition of fixed-point sin tables. Signed-off-by: Mans Rullgard <mans@mansr.com>
* Simplify CLEANFILES make variable by using wildcards.Diego Biurrun2011-05-19
| | | | Also ensures that generated file cos_fixed_tables.c is deleted on 'make clean'.
* Move some mpegaudio functions to new mpegaudiodsp subsystemMans Rullgard2011-05-19
| | | | | | | | This separation allows these functions to be used in a cleaner fashion from other codecs (e.g. qdm2) and simplifies creating optimised versions of them. Signed-off-by: Mans Rullgard <mans@mansr.com>
* dct: build dct32 as separate object filesMans Rullgard2011-05-17
| | | | | | | This builds the float and fixed-point versions of dct32 separately instead of #including the file in dct.c and mpegaudiodec.c. Signed-off-by: Mans Rullgard <mans@mansr.com>
* Remove unused header mpegaudio3.h.Diego Biurrun2011-05-16
| | | | The header is a part of an MP3 encoder that never saw the light of day.
* Port SMPTE S302M audio decoder from FFmbc 0.3.Baptiste Coudurier2011-05-11
|
* mpegaudio: remove CONFIG_MPEGAUDIO_HP optionMans Rullgard2011-05-09
| | | | | | | The low quality mode is off by default and never tested. The high quality mode is also plenty fast enough. Signed-off-by: Mans Rullgard <mans@mansr.com>

* lavc: provide the opt.h header until the next bumpAnton Khirnov2011-04-21
| | | | AVOptions were moved to libavutil only recently.
* lavc: remove reference to opt.h from Makefile.Anton Khirnov2011-04-19

* Move sine windows to a separate fileMans Rullgard2011-03-20
| | | | | | | These windows do not really belong in fft/mdct files and were easily confused with the similarly named tables used by rdft. Signed-off-by: Mans Rullgard <mans@mansr.com>
* Move ff_kbd_window_init() to a separate fileMans Rullgard2011-03-19
| | | | | | | This function is not tightly coupled to mdct, and it's in the way of making a fixed-point mdct implementation. Signed-off-by: Mans Rullgard <mans@mansr.com>
* Remove Sonic experimental audio codecMans Rullgard2011-03-19
| | | | | | | | Since initially committed in 2004, this codec has only been touched for maintenanance. Functionally, it contains no novel ideas and its intended audience is better served by existing mature codecs. Signed-off-by: Mans Rullgard <mans@mansr.com>

* Merge libavcore into libavutilReinhard Tartler2011-02-15
| | | | | | | | | | | | It is pretty hopeless that other considerable projects will adopt libavutil alone in other projects. Projects that need small footprint are better off with more specialized libraries such as gnulib or rather just copy the necessary parts that they need. With this in mind, nobody is helped by having libavutil and libavcore split. In order to ease maintenance inside and around FFmpeg and to reduce confusion where to put common code, avcore's functionality is merged (back) to avutil.
