Michael Niedermayer	327a968817	avcodec/cngdec: Remove AV_CODEC_CAP_DELAY As is the decoder will never stop, it will cause an infinite loop. The RFC seems only to speak of non empty packets so endlessly generating noise from the last empty flush packets seems wrong.

Michael Niedermayer	e7b9d136a1	avcodec/cngdec: Check skip_samples Without this its possible to make the new decode API decode billions of samples out of a empty input and never return to the caller before all samples have been created and discarded.

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.

Martin Storsjö	9b500b8f6c	avcodec: Add a RFC 3389 comfort noise codec This isn't too useful as a normal codec, but can be used in voip style applications. The decoder updates the noise generator parameters when a packet is given to it for decoding, but if called with an empty packet, it generates more noise according to the last parameters.
