Luca Barbato	5264e7ba21	ac3: Check the array bound before dereferencing CC: libav-stable@libav.org Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	9 years ago
Vittorio Giovara	a67b67944a	ac3enc_template: Use the correct context field For audio encoders, delay has no effect, use the appropriate one, initial_padding (see `2df0c32`).	10 years ago
Michael Niedermayer	e36db49b7b	avcodec: Add a min size parameter to ff_alloc_packet2() This parameter can be used to inform the allocation code about how much downsizing might occur, and can be used to optimize how to allocate the packet Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	10 years ago
Michael Niedermayer	cae851c789	avcodec/ac3enc: Use avpriv_float_dsp_alloc() Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago

James Zern	bcaf64b605	normalize calls to ff_alloc_packet2 - check ret < 0 - remove excessive error log Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Michael Niedermayer	f6fff8e546	ac3enc_template: silence may be used uninitialized in this function warnings Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Diego Biurrun	218aefce44	dsputil: Move LOCAL_ALIGNED macros to libavutil	12 years ago
Michael Niedermayer	ebe368d5d8	ac3enc: fix 'warning: block0 may be used uninitialized in this function' The pointer is also initialized to NULL for safety. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Justin Ruggles	b1540fc884	(e)ac3enc: use planar sample format	12 years ago
Justin Ruggles	d5a7229ba4	Add a float DSP framework to libavutil Move vector_fmul() from DSPContext to AVFloatDSPContext.	13 years ago
Paul B Mahol	ae2c33b0c2	cosmetics: remove superfluous curly brackets Signed-off-by: Paul B Mahol <onemda@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Michael Niedermayer	7d3ef3840b	ac3enc: switch to ff_alloc_packet2(). Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Justin Ruggles	aa872af5e3	ac3enc: update to AVCodec.encode2() Update FATE references due to encoder delay.	13 years ago
Diego Biurrun	a8798c7eb9	Drop unnecessary av_uninit attributes from some variable declarations. Recent versions of gcc (4.4+) no longer give false positive warnings.	13 years ago
Michael Niedermayer	6ffdc262b0	ac3enc: clenaup project name in one comment Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago
Justin Ruggles	c2d9a65bc0	ac3enc: doxygen update. Add some parameters to existing function documentation. Remove some unneeded documentation. Convert some static function documentation to non-doxygen style.	13 years ago
Justin Ruggles	ae264bb29b	ac3enc: Add channel coupling support for the fixed-point AC-3 encoder. Update FATE references accordingly.	14 years ago
Justin Ruggles	a0d17b6d45	ac3enc: scale floating-point coupling channel coefficients in scale_coefficients() rather than in apply_channel_coupling()	14 years ago
Justin Ruggles	3e5722a8ca	ac3enc: fix encoding of stereo ac3 files when rematrixing is disabled. The number of rematrixing bands still needs to be calculated.	14 years ago
Justin Ruggles	3be5a94351	ac3enc: remove outdated TODO comment for apply_channel_coupling()	14 years ago
Justin Ruggles	069083a419	ac3enc: clip coupling coordinates during calculation This is faster than using the clip_coefficients() function. Also, clipping the coordinates before determining reuse is better since it will compare coordinates that are closer to their final encoded values.	14 years ago
Justin Ruggles	d1d33e0763	ac3enc: remove unneeded #include	14 years ago
Justin Ruggles	fce33f9ead	ac3enc: restructure coupling coordinate reuse calculation	14 years ago
Justin Ruggles	c3d63262fe	ac3enc: allow new coupling coordinates to be sent independently for each channel.	14 years ago
Justin Ruggles	d55ad59a8a	ac3enc: separate exponent bit counting from exponent grouping. Move bit counting to the bit allocation function. Move exponent grouping to after bit allocation. This will allow for adjustment of bandwidth parameters during bit allocation without having to do exponent grouping multiple times.	14 years ago
Justin Ruggles	1bca72e1bd	eac3enc: support writing of basic mixing and info metadata	14 years ago
Justin Ruggles	be7bd626c4	eac3enc: use different numbers of blocks per frame to allow higher bitrates	14 years ago
Justin Ruggles	b5849f7709	ac3enc: merge AC3MDCTContext with AC3EncodeContext. Since both the fixed-point and floating-point encoders use the FFTContext, this no longer needs to be in a separate context. Also, when a short-transform context is added, the same MDCT window will be used.	14 years ago
Justin Ruggles	82cea7cb6c	ac3enc: prefer passing AC3EncodeContext rather than AVCodecContext	14 years ago
Mans Rullgard	f507a9fe00	ac3enc: move inner loop of compute_rematrixing_strategy to ac3dsp	14 years ago
Justin Ruggles	523b7eba19	ac3enc: clip coefficients after MDCT. This ensures that any processing between the MDCT and exponent extraction will be using clipped coefficients.	14 years ago
Justin Ruggles	8683c6a638	ac3enc: move ff_ac3_encode_frame() to ac3enc_template.c This avoids using function pointers for quite a few small functions, most of which just call DSP functions.	14 years ago
Justin Ruggles	b203f65451	ac3enc: use correct alignment and length in channel coupling dsp functions. This fixes a segfault when using the C version of ac3dsp.float_to_fixed24().	14 years ago
Justin Ruggles	99477adc31	ac3enc: fix allocation of floating point samples. sizeof(SampleType) is different for fixed and float encoders.	14 years ago
Justin Ruggles	e0cc66df61	ac3enc: split templated float vs. fixed functions into a separate file. Function pointers are used for templated functions instead of needlessly duplicating many functions.	14 years ago
