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	23 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
