Nicolas George	183ce55b0d	lavfi: split frame_count between input and output. AVFilterLink.frame_count is supposed to count the number of frames that were passed on the link, but with min_samples, that number is not always the same for the source and destination filters. With the addition of a FIFO on the link, the difference will become more significant. Split the variable in two: frame_count_in counts the number of frames that entered the link, frame_count_out counts the number of frames that were sent to the destination filter.	8 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.

Ganesh Ajjanagadde	4d0d85c94a	avfilter/af_volume: use log10 instead of log()/M_LN10 This is likely more precise and conveys the intent better. Reviewed-by: Michael Niedermayer <michael@niedermayer.cc> Signed-off-by: Ganesh Ajjanagadde <gajjanagadde@gmail.com>	9 years ago

Gilles Chanteperdrix	dcf19008a6	avfilter/af_volume: fix precision=fixed and volume=0 case When precision is fixed and volume is 0, filter_frame does not perform any operation on the output buffer. This works if the output buffer has been allocated and zeroed with ff_get_audio_buffer but not if the input buffer is used as output buffer. Fix this by not using the input buffer as output buffer if precision is fixed and volume is 0.
