Diego Biurrun	aaf47bcde7	Drop ALT_ prefix from BITSTREAM_READER_LE name. The prefix is a historic remnant that probably meant "alternative". Now that the A32 bitstream reader has been dropped it makes no sense anymore.	13 years ago
Mans Rullgard	3383a53e7d	lavu: replace int/float punning functions The existing functions defined in intfloat_readwrite.[ch] are both slow and incorrect (infinities are not handled). This introduces a new header with fast, inline conversion functions using direct union punning assuming an IEEE-754 system, an assumption already made throughout the code. The one use of Intel/Motorola extended 80-bit format is replaced by simpler code sufficient under the present constraints (positive normal values). The old functions are marked deprecated and retained for compatibility. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Justin Ruggles	0eea212943	Add avcodec_decode_audio4(). Deprecate avcodec_decode_audio3(). Implement audio support in avcodec_default_get_buffer(). Implement the new audio decoder API in all audio decoders.	13 years ago
Justin Ruggles	add7b1140f	binkaudio: expand quant_table to accommodate all possible values	13 years ago
Justin Ruggles	425a843505	binkaudio: change short to int16_t	13 years ago
Justin Ruggles	4f4e19480a	binkaudio: only decode one block at a time. This prevents truncating output due to an output buffer that is too small for all blocks. There is no limit on the number of blocks in a packet.	13 years ago
Justin Ruggles	eaddd29e00	binkaudio: store interleaved overlap samples in BinkAudioContext. This fixes the requirement for the buffer size to be larger than the number of samples actually decoded.	13 years ago
Justin Ruggles	9f48039a37	binkaudio: pre-calculate quantization factors	13 years ago
Justin Ruggles	101ef19ef4	binkaudio: add some buffer overread checks. This stops decoding before overreads instead of after.	13 years ago
Anton Khirnov	ec6402b7c5	lavc: use designated initialisers for all codecs. It's more readable and less prone to breakage.	14 years ago
Kostya	df64da3b1e	bink: pass Bink version to audio decoder through extradata instead of codec_tag. This is needed because not all players (e.g. MPlayer) are able to distinguish two different Bink audio decoders when codec_tag is set. Signed-off-by: Anton Khirnov <anton@khirnov.net>	14 years ago
Vitor Sessak	9d35fa520e	Add AVX FFT implementation. Signed-off-by: Reinhard Tartler <siretart@tauware.de>	14 years ago
Mans Rullgard	0aded9484d	Move dct and rdft definitions to separate files This leaves fft.h with only the core FFT and MDCT definitions thus making it more managable. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	26f548bb59	fft: remove inline wrappers for function pointers This removes the rather pointless wrappers (one not even inline) for calling the fft_calc and related function pointers. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	2912e87a6c	Replace FFmpeg with Libav in licence headers Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Peter Ross	ccfcddb3f2	Bink version 'b' audio decoder Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Peter Ross	8a8c283edd	binkaudio: simplify frame_len_bits and frame_len calculation Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Peter Ross	a304def1dc	binkaudio: remove unnecessary loop decode_init sets bands[0] == 2, so this loop always sets the band table index (k) to zero. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Peter Ross	582ac86d19	binkaudio: perform band table scaling in decode_init Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Peter Ross	71f88b1f38	binkaudio: remove unused copy of AVCodecContext* Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Peter Ross	9806fbd535	binkaudio: fix channel count check Perform validity check on AVFormatContext.channels instead of uninitialised field. This fixes issue 2001. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Justin Ruggles	c73d99e672	Separate format conversion DSP functions from DSPContext. This will be beneficial for use with the audio conversion API without requiring it to depend on all of dsputil. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Justin Ruggles	9d06d7bce3	Remove the add bias hack for the C version of DSPContext.float_to_int16_*().	14 years ago
Diego Elio Pettenò	d36beb3f69	Add ff_ prefix to data symbols of encoders, decoders, hwaccel, parsers, bsf. None of these symbols should be accessed directly, so declare them as hidden. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Stefano Sabatini	5d6e4c160a	Replace deprecated symbols SAMPLE_FMT_* with AV_SAMPLE_FMT_*, and enum SampleFormat with AVSampleFormat. Originally committed as revision 25730 to svn://svn.ffmpeg.org/ffmpeg/trunk	14 years ago
Diego Biurrun	ba87f0801d	Remove explicit filename from Doxygen @file commands. Passing an explicit filename to this command is only necessary if the documentation in the @file block refers to a file different from the one the block resides in. Originally committed as revision 22921 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Vitor Sessak	c2b774a04e	Make code using 1d-DCT consistent with the API change Originally committed as revision 22792 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Stefano Sabatini	72415b2adb	Define AVMediaType enum, and use it instead of enum CodecType, which is deprecated and will be dropped at the next major bump. Originally committed as revision 22735 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Peter Ross	b41ec742ea	Make binkaudio work with ff_float_to_int16_interleave_c (martin at martin dot st) Originally committed as revision 22466 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	41ea18fb0d	Give RDFT types more meaningful names Originally committed as revision 22290 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	1429224b04	Move FFT parts from dsputil.h to fft.h Originally committed as revision 22235 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Måns Rullgård	84dc2d8afa	Remove DECLARE_ALIGNED_{8,16} macros These macros are redundant. All uses are replaced with the generic DECLARE_ALIGNED macro instead. Originally committed as revision 22233 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
Peter Ross	54063e37c1	Perform coefficient transformations in Bink Audio DCT decoder (issue1770) Originally committed as revision 22167 to svn://svn.ffmpeg.org/ffmpeg/trunk	15 years ago
