Carl Eugen Hoyos	724cf83f10	Remove some unneeded casts of bit_rate.	7 years ago
Daniil Cherednik	9c4e69b8ea	avcodec/dcaenc: Do not abort process in case of bitrate deficit Old behaviour - abort if at least one subband has 1bit quantizer and consumed_bits still greater than frame_bits size. It was a bit strange - we still could reduce bits consumption by reducing SNR for other subbands. Same strange logic with upper threshold - stop bits allocation if at least one subband reach 26bits. New behaviour - if consumed_bits greater than frame_bits and all subbands has 1 bit quantizer we restart bits allocation and allow zero subbands.	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

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.
