2017-02-14avfilter/vf_lut: make it possible to clip pixel values that are out of valid ↵Paul B Mahol
range Previous behavior was not useful at all as such pixels where all mapped to 0. Signed-off-by: Paul B Mahol <onemda@gmail.com>
2017-02-14avfilter/vf_lut: do not always explicitly clip pixelsPaul B Mahol
Old behaviour was not useful at all. New behaviour only emulate old behaviour with default options. Signed-off-by: Paul B Mahol <onemda@gmail.com>

2016-01-27avutil: Rename FF_CEIL_COMPAT to AV_CEIL_COMPATDerek Buitenhuis
Libav, for some reason, merged this as a public API function. This will aid in future merges. A define is left for backwards compat, just in case some person used it, since it is in a public header. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>

2013-05-12lavfi: replace passthrough_filter_frame with a flag.Clément Bœsch
With the introduction of AVFilterContext->is_disabled, we can simplify the custom passthrough mode in filters. This commit is technically a small compat break, but the timeline was introduced very recently. Doxy by Stefano Sabatini.
