Justin Ruggles	d5a7229ba4	Add a float DSP framework to libavutil Move vector_fmul() from DSPContext to AVFloatDSPContext.	13 years ago
Justin Ruggles	aa872af5e3	ac3enc: update to AVCodec.encode2() Update FATE references due to encoder delay.	13 years ago
Mans Rullgard	cc276c85d1	Make channel layout masks unsigned It makes more sense for a bit mask to use an unsigned type. The change should be source and binary compatible on all supported systems, hence micro version bump. Fixes a few invalid shifts. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
John Stebbins	5f3fb59953	fix AC3ENC_OPT_MODE_ON/OFF The values were reversed. Signed-off-by: Justin Ruggles <justin.ruggles@gmail.com>	13 years ago
Justin Ruggles	ae264bb29b	ac3enc: Add channel coupling support for the fixed-point AC-3 encoder. Update FATE references accordingly.	13 years ago
Justin Ruggles	c766eb1ce1	ac3enc: add macros for option names to make them more understandable.	13 years ago
Justin Ruggles	c3d63262fe	ac3enc: allow new coupling coordinates to be sent independently for each channel.	13 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.	13 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	08a747afb9	eac3enc: use frame exponent strategy when applicable. This checks if the set of selected exponent strategies for all blocks in a channel are in the frame exponent strategy table, and if so, writes the table index instead of each strategy. This saves up to 7 bits per channel per frame, so the overall effect on quality is small.	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	0e4dbe2996	ac3enc: avoid masking output in asym_quant() by using signed values for quantized mantissas.	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	38c304addd	ac3enc: remove empty ac3_float function that is never called	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
Justin Ruggles	e754dfc0bb	ac3enc: dynamically allocate AC3EncodeContext fields windowed_samples and mdct This will allow the same struct to be used for both the fixed and float ac3 encoders.	14 years ago
Justin Ruggles	36151b3e31	ac3enc: use function pointer to choose between AC-3 and E-AC-3 header output functions.	14 years ago
Justin Ruggles	c8e9ea43d0	Move E-AC-3 encoder functions to a separate eac3enc.c file.	14 years ago
Fabrice Bellard	6107fa87b4	preparing integration of new AC3 decoder Originally committed as revision 1089 to svn://svn.ffmpeg.org/ffmpeg/trunk	22 years ago
Zdenek Kabelac	30b68f33aa	* encoding of AC3 with more than 2 channels by Takashi Iwai <tiwai@suse.de> Originally committed as revision 383 to svn://svn.ffmpeg.org/ffmpeg/trunk	23 years ago
Fabrice Bellard	de6d9b6404	Initial revision Originally committed as revision 5 to svn://svn.ffmpeg.org/ffmpeg/trunk	24 years ago
