Justin Ruggles	3b7d43383f	twinvq: decode directly to the user-provided AVFrame	12 years ago
Ronald S. Bultje	5959bfaca3	floatdsp: move butterflies_float from dsputil to avfloatdsp. This makes wmadec/enc, twinvq and mpegaudiodec (i.e. mp2/mp3) independent of dsputil.	12 years ago
Justin Ruggles	e034cc6c60	lavc: Move vector_fmul_window to AVFloatDSPContext Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	12 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	a903f8f087	Include libavutil/channel_layout.h instead of libavutil/audioconvert.h Also reorder some other #include when applicable.	12 years ago
Michael Niedermayer	98b377004d	twinvq: make ibps check unsigned Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	b8dc5f8bb3	twinvq: check bitrate for validity avoid division by 0 Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Justin Ruggles	b5f628e227	twinvq: validate sample rate code A large invalid value could cause undefined behavior when left-shifted by 8 later in the function.	12 years ago
Justin Ruggles	335826cf5f	twinvq: set channel layout	12 years ago
Justin Ruggles	8cc72ce5a0	twinvq: validate that channels is not <= 0 This could occur due to integer overflow when reading the channel count from the extradata.	12 years ago
Justin Ruggles	1478a3601e	twinvq: use planar sample format	12 years ago
Anton Khirnov	36ef5369ee	Replace all CODEC_ID_* with AV_CODEC_ID_*	13 years ago
Justin Ruggles	d5a7229ba4	Add a float DSP framework to libavutil Move vector_fmul() from DSPContext to AVFloatDSPContext.	13 years ago
Mans Rullgard	4bf2e7c5f1	twinvq: fix out of bounds array access ModeTab.fmode has only 3 elements, so indexing it with ftype in the initialier for 'size' is invalid when ftype == FT_PPC. This fixes crashes with gcc 4.8. Signed-off-by: Mans Rullgard <mans@mansr.com>	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
Michael Niedermayer	35f707abe1	twinnvq: remove ;; Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	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	9d06037d48	twinvq: add SSE/AVX optimized sum/difference stereo interleaving	13 years ago
Justin Ruggles	7b966566da	vqf/twinvq: pass vqf COMM chunk info in extradata This is needed because the twinvq decoder cannot rely on bit_rate to be set. The API documentation says that bit_rate is set by libavcodec, not by the user.	13 years ago
Justin Ruggles	a8a6da4a0e	twinvq: check for allocation failure in init_mdct_win()	13 years ago
Justin Ruggles	e53eecd0e7	twinvq: check output buffer size before decoding	13 years ago

Diego Biurrun	adbfc605f6	doxygen: Consistently use '@' instead of '\' for Doxygen markup. Signed-off-by: Diego Biurrun <diego@biurrun.de>	14 years ago
Diego Biurrun	046f3cb789	vorbis: Rename decoder/encoder files to follow general file naming scheme.	14 years ago
Mans Rullgard	4538729afe	Move sine windows to a separate file 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>	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
Justin Ruggles	a8ae4e0e7b	Remove unneeded add bias from 3 functions. DSPContext.vector_fmul_window() DCADSPContext.lfe_fir() SynthFilterContext.synth_filter_float() Signed-off-by: Mans Rullgard <mans@mansr.com> (cherry picked from commit `80ba1ddb58`)	14 years ago

Diego Elio Pettenò	e7e2df27f8	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> (cherry picked from commit `d36beb3f69`)	14 years ago
