* all: move ff_exp10, ff_exp10f, ff_fast_powf to lavu/ffmath.hGanesh Ajjanagadde2016-03-22
| | | | | | | | | | | 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. Bultje <rsbultje@gmail.com> Signed-off-by: Ganesh Ajjanagadde <gajjanag@gmail.com>

* avfilter/af_compand: do not clip; allow >0dB curve pointsPaul B Mahol2015-12-02
| | | | | | | Do not clip output samples, so that clipping can be handled by other filters. Alow setting curve points above 0dB. This is useful when operating with floats. Signed-off-by: Paul B Mahol <onemda@gmail.com>

* avfilter: use ff_all_channel_counts() instead of ff_all_channel_layouts()Paul B Mahol2015-09-12

* avfilter/af_compand: fix clipping with default optionsPaul B Mahol2015-07-17
| | | | | | | | | Decays and attacks where by default set only for first channel which caused poor defaults to be used which produced clipping on any higher channel. Reported-by: lachs0r Signed-off-by: Paul B Mahol <onemda@gmail.com>

|\ | | | | | | | | | | | | | | * commit 'd3cfd7aff86ee3d449ca68aba21d67b9b2136a9b': af_compand: make sure request_frame always outputs at least one frame See: 6b68e2a43b3407522080be50a2a19cff2f9715ef Merged-by: Michael Niedermayer <michaelni@gmx.at>
| * af_compand: make sure request_frame always outputs at least one frameAndrew Kelley2014-07-08
| | | | | | | | | | | | | | | | | | | | | | This fixes a segmentation fault because request_frame in fifo.c assumes that the call to ff_request_frame will populate fifo->root.next. Before, it was possible for request_frame in af_compand to not do this, resulting in a null pointer access. Now, request_frame in af_compand always will return at least one frame or an error, as per the API specifications in avfilter.h for request_frame. Signed-off-by: Anton Khirnov <anton@khirnov.net>
