* Mark parameterless function declarations as 'void'.Diego Biurrun2011-05-26

* ac3enc: initialize all coefficients to zero.Justin Ruggles2011-05-25
| | | | | | | | Uninitialized coefficients were being used to generate exponents, some of which actually ended up in the final stream. Even though, they were just extra exponents that are not used by any decoder, it is still better to have consistent output for testing. This also fixes valgrind errors.
* Remove h263_msmpeg4 from MpegEncContext.Alex Converse2011-05-25
| | | | It was long ago superseded by msmpeg4_version.
* Move emms_c() from libavcodec to libavutil.Ronald S. Bultje2011-05-24
|
* tiff: set palette in the context when specified in TIFF_PAL tagStefano Sabatini2011-05-24
| | | | | | | | | | | Since image initialization was moved after tag parsing, the palette needs to be specified in the context and then copied to the allocated image in init_image(). Fixes a regression with TIFF images that have palette data, trac issue #230, file Test_Flate_8bpp.tif. Signed-off-by: Diego Biurrun <diego@biurrun.de>
* pgssubdec: fix incorrect colors.Alexandre Colucci2011-05-24
| | | | | | | | | On Blu-ray colors are stored in the order YCrCb (and not YCbCr) as mentioned in the specifications: see System Description Blu-ray Disc Read-Only Format, 9.14.4.2.2.1 Palette Definition Segment When decoding a Blu-ray subtitle, the colors were incorrectly set. Signed-off-by: Anton Khirnov <anton@khirnov.net>
* dvdsubdec: fix incorrect colors.Alexandre Colucci2011-05-24
| | | | | | | | | | | | On DVD and HD-DVD colors are stored in the order YCrCb (and not YCbCr) as mentioned in the specifications: see DVD Specifications for Read-Only Disc / Part 3, 4.3 Program Chain Information (7) PGC_SP_PLT see DVD Specifications for High Definition Disc, 5.2 Navigation for Standard Content (11) PGC_SDSP_PLT see DVD Specifications for High Definition Disc, 5.2 Navigation for Standard Content (12) PGC_HDSP_PLT see DVD Specifications for High Definition Disc, 5.5 Presentation Data (4) SET_COLOR2 When decoding a DVD or HD-DVD subtitle, the colors were incorrectly set.

* msmpeg4: reindent.Anton Khirnov2011-05-24

* 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.
* ac3enc: add channel coupling supportJustin Ruggles2011-05-24
| | | | | | | | | Channel coupling is an optional AC-3 feature that increases quality by combining high frequency information from multiple channels into a single channel. The per-channel high frequency information is sent with less accuracy in both the frequency and time domains. This allows more bits to be used for lower frequencies while preserving enough information to reconstruct the high frequencies.
* aacdec: fix typo in scalefactor clipping checkJustin Ruggles2011-05-23

* h264: Properly set coded_{width, height} when parsing H.264.Felipe Contreras2011-05-23

* x86 asm: Add SECTION_TEXT to dct32_sse.asm.Dave Yeo2011-05-23
| | | | | | | This fixes the following error on OS/2: error: segment name `.text align=16' not recognized Signed-off-by: Diego Biurrun <diego@biurrun.de>
* dct32_sse: eliminate some spillsLoren Merritt2011-05-22
| | | | 125->104 cycles on penryn (x86_64 only)
* Fix dct32() compilation with --disable-yasmVitor Sessak2011-05-22
| | | | Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
* dct32: Add AVX implementation of 32-point DCTVitor Sessak2011-05-21

* dct32: Change pass 6 permutation to allow for AVX implementationVitor Sessak2011-05-21
|
* dct32: port SSE 32-point DCT to YASMVitor Sessak2011-05-21
|
* multiple inclusion guard cleanupDiego Biurrun2011-05-21
| | | | | Add missing multiple inclusion guards; clean up #endif comments; add missing library prefixes; keep guard names consistent.
* svq3: Do initialization after parsing the extradataRonald S. Bultje2011-05-21
| | | | | | | | If done before, some parameters aren't known yet. With svq3/rtp, initializing before some parameters are known can lead to calling av_malloc(0), which on OS X currently returns broken pointers.
* mp3lame: add #include required for AV_RB32 macro.Ronald S. Bultje2011-05-20
| | | | Fixes compilation with mp3lame enabled.
* LATM/AAC: Free previously initialized context on reinit.Ronald S. Bultje2011-05-20
| | | | | | | | Fixes memory leaks which are the result of overwriting already-initialized MDCT contexts during context reinitialization, e.g. in valgrind fate-aac-latm_000000001180bc60. Signed-off-by: Diego Biurrun <diego@biurrun.de>
* Add support for a.out object format to assembler macros.Dave Yeo2011-05-20
| | | | | | This format is still used by e.g. OS/2. Signed-off-by: Diego Biurrun <diego@biurrun.de>

* qdm2: Use floating point synthesis filter.Vitor Sessak2011-05-19
| | | | | | This avoid needlessly convertion from floating point to fixed point and back. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
* h264: correct border check.Ronald S. Bultje2011-05-19
| | | | | | | | | When backing up the top-left border, check that the top-left (rather than left) MB indeed does belong to our slice. If it doesn't, backing up has no positive effect but may accidentally interfere with other threads writing in the same space. Fixes occasional one-off effects when enabling slice-MT.
* h264: fix loopfilter with threading at slice boundaries.Ronald S. Bultje2011-05-19
|
* Fix ff_mpa_synth_filter_fixed() prototypeMans Rullgard2011-05-20
| | | | | | | The prototype should use the same typedefs as the definition, or it will fail where int32_t is not int (DOS apparently). Signed-off-by: Mans Rullgard <mans@mansr.com>
* 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>
* Remove potentially unstable filenames from comments in generated files.Diego Biurrun2011-05-19

* 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'.

* mpegaudio: move some struct definitions from mpegaudio.hMans Rullgard2011-05-19
| | | | | | | These structs are only used in mpegaudiodec.c, so move them there and remove no longer needed #include lines from mpegaudio.h. Signed-off-by: Mans Rullgard <mans@mansr.com>
* 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>
* g729: Merge g729.h into g729dec.c.Diego Biurrun2011-05-19
| | | | The header contains just a single define that is only used in g729dec.c.
* 10l: wrap float_interleave functions in HAVE_YASM.Justin Ruggles2011-05-18
| | | | fixes compilation with --disable-yasm
* Add floating-point sample format support to the ac3, eac3, dca, aac, and vorbisJustin Ruggles2011-05-18
| | | | | | decoders. Based on patches by clsid2 in ffdshow-tryout.
* Add request_sample_fmt field to AVCodecContext.Justin Ruggles2011-05-18
| | | | | This will allow audio decoders to support output of different sample formats as a runtime option.
* Add float_interleave() to FmtConvertContext with x86-optimized versions.Justin Ruggles2011-05-18
| | | | | Partially based on patches by clsid2 in ffdshow-tryout. ff_float_interleave6() x86 improvements by Loren Merrit.
* mpegaudiodec: remove decode_end() functionMans Rullgard2011-05-18
| | | | | | | This function is not needed since 721d6f2dc5 removed the DCT table allocations for the configuration used here. Signed-off-by: Mans Rullgard <mans@mansr.com>
* mpegaudio: sanitise compute_antialias_* namesMans Rullgard2011-05-18
| | | | | | | This makes the compute_antialias functions use the same naming convention as everything else. Signed-off-by: Mans Rullgard <mans@mansr.com>
