Daniil Cherednik	a6191d098a	dcaenc: Reverse data layout to prevent data copies during Huffman encoding introduction Reviewed-by: Rostislav Pehlivanov <atomnuker@gmail.com>	8 years ago
foo86	b286ff69c0	avcodec/dcaenc: move channel reordering tables to dcaenc.h DCA core decoder no longer uses fixed tables for channel reordering. Move them into private encoder header (and drop ff_dca_ prefix). Signed-off-by: James Almer <jamrial@gmail.com>	9 years ago
foo86	de28e73cce	avcodec/dcaenc: reuse shared quant levels table Signed-off-by: James Almer <jamrial@gmail.com>	9 years ago
Ganesh Ajjanagadde	db1a642cd2	all: move ff_exp10, ff_exp10f, ff_fast_powf to lavu/ffmath.h The idea is to use ffmath.h for internal implementations of math functions. Currently, it is used for variants of libm functions, but is by no means limited to such things. Note that this is not exported; use lavu/mathematics for such purposes. Reviewed-by: Ronald S.

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>	9 years ago

Paul B Mahol	e1ba5fc968	dcaenc: update Long story short: previous code was useless and was port of older dcaenc, this commit just "sync" with current dcaenc, hopefuly making this encoder more useful. Signed-off-by: Paul B Mahol <onemda@gmail.com>	12 years ago
