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
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
