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.

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.

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.

1776177b7f lavfi: replace passthrough_filter_frame with a flag. 
With the introduction of AVFilterContext->is_disabled, we can simplify

This commit is technically a small compat break, but the timeline was
introduced very recently.
