Age	Commit message (Collapse)	Author
2012-06-08	Add a float DSP framework to libavutil	Justin Ruggles
	Move vector_fmul() from DSPContext to AVFloatDSPContext.
2012-03-21	ac3enc: update to AVCodec.encode2()	Justin Ruggles
	Update FATE references due to encoder delay.
2011-11-25	Make channel layout masks unsigned	Mans Rullgard
	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>
2011-10-11	fix AC3ENC_OPT_MODE_ON/OFF	John Stebbins
	The values were reversed. Signed-off-by: Justin Ruggles <justin.ruggles@gmail.com>
2011-09-05	ac3enc: Add channel coupling support for the fixed-point AC-3 encoder.	Justin Ruggles
	Update FATE references accordingly.
2011-08-11	ac3enc: add macros for option names to make them more understandable.	Justin Ruggles

2011-08-10	ac3enc: allow new coupling coordinates to be sent independently for each	Justin Ruggles
	channel.
2011-08-10	ac3enc: separate exponent bit counting from exponent grouping.	Justin Ruggles
	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.
2011-07-27	eac3enc: support writing of basic mixing and info metadata	Justin Ruggles

2011-07-21	eac3enc: use different numbers of blocks per frame to allow higher bitrates	Justin Ruggles

2011-07-19	eac3enc: use frame exponent strategy when applicable.	Justin Ruggles
	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.
2011-07-14	ac3enc: merge AC3MDCTContext with AC3EncodeContext.	Justin Ruggles
	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.
2011-07-14	ac3enc: prefer passing AC3EncodeContext rather than AVCodecContext	Justin Ruggles

2011-07-01	ac3enc: clip coefficients after MDCT.	Justin Ruggles
	This ensures that any processing between the MDCT and exponent extraction will be using clipped coefficients.
2011-06-27	ac3enc: move ff_ac3_encode_frame() to ac3enc_template.c	Justin Ruggles
	This avoids using function pointers for quite a few small functions, most of which just call DSP functions.
2011-06-22	ac3enc: avoid masking output in asym_quant() by using signed values for	Justin Ruggles
	quantized mantissas.
2011-06-14	ac3enc: fix allocation of floating point samples.	Justin Ruggles
	sizeof(SampleType) is different for fixed and float encoders.
2011-06-14	ac3enc: remove empty ac3_float function that is never called	Justin Ruggles

2011-06-14	ac3enc: split templated float vs. fixed functions into a separate file.	Justin Ruggles
	Function pointers are used for templated functions instead of needlessly duplicating many functions.
2011-06-14	ac3enc: dynamically allocate AC3EncodeContext fields windowed_samples and mdct	Justin Ruggles
	This will allow the same struct to be used for both the fixed and float ac3 encoders.
2011-06-14	ac3enc: use function pointer to choose between AC-3 and E-AC-3 header output	Justin Ruggles
	functions.
2011-06-07	Move E-AC-3 encoder functions to a separate eac3enc.c file.	Justin Ruggles
