Diego Biurrun	f20518568a	build: Split WMA frequencies into a separate object file These are the only WMA bits shared with binkaudio. Splitting them off reduces the binnkaudio dependency on general WMA code.	10 years ago

Anton Khirnov	594d4d5df3	lavc: add a wrapper for AVCodecContext.get_buffer(). It will be useful in the upcoming transition to refcounted AVFrames.	12 years ago

Justin Ruggles	ee90119e9e	binkaudio: remove unneeded GET_BITS_SAFE macro Normal get_bits() already has overread protection.	12 years ago

Martin Storsjö	00c3b67b8a	cosmetics: Align codec declarations Also break some long lines, remove codec function placeholder comments and add spaces in sample/pixel format lists. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Martin Storsjö	9cf0841ef3	dsputil: Add ff_ prefix to the dsputil_init functions Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
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.	13 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
Ivan Kalvachev	093768c9a4	Fix bink audio playback outside of FFmpeg. There are 2 known Bink audio codecs. Additionally they have a different flavor if they are found inside Bink-b "BIKb" file. In order to guess the correct flavor, the demuxer sets the audio codec_tag to be the same as the file format tag. This causes problem because same tag is used for both audio codecs. The hack works in FFmpeg because audio codecs are identified by their codec_id, but other players rely on standard behavior. This fix removes the codec_tag hack and instead uses artificial extradata format to signal the codec flavor. This would also allow proper embedding of Bink audio in other containers.
