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>

This is shorter and consistent across filters.
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.

2013-04-23lavfi: add timeline support.Clément Bœsch
Flag added in a few simple filters. A bunch of other filters can likely use the feature as well.

2013-03-28lavfi/gradfun: fix rounding in MMX code.Clément Bœsch
Current code divides before increasing precision. Also reduce upper bound for strength from 255 to 64. This will prevent an overflow in the SSSE3 and MMX filter_line code: delta is expressed as an u16 being shifted by 2 to the left. If it overflows, having a strength not above 64 will make sure that m is set to 0 (making the m*m*delta >> 14 expression void). A value above 64 should not make any sense unless gradfun is used as a blur filter. Signed-off-by: Anton Khirnov <anton@khirnov.net>

This breaks usage for out-of-range values.
2012-12-19lavfi/gradfun: reduce up limit for threshold.Clément Bœsch
This will prevent an overflow in the SSSE3 and MMX filter_line code: delta is expressed as an u16 being shifted by 2 to the left. If it overflows, having a strength not above 64 will make sure that m is set to 0 (making the m*m*delta >> 14 expression void). A value above 64 should not make any sense unless gradfun is used as a blur filter.

First DC is only used once otherwise. This also makes the code consistent with ASM versions.
2012-12-04lavfi: remove some video w/h settings after avfilter_copy_buffer_ref_props.Clément Bœsch
video->[wh] will be set with the same values as the input after avfilter_copy_buffer_ref_props. These filters don't change the size of the input so there is no need for this code.
2012-12-03lavfi/gradfun: remove check for AV_PERM_PRESERVE.Clément Bœsch
This check does not make sense in this context, see doc/filter_design.txt for details about the usage of such flag.

Any alleged performance benefits gained from the split are purely mythological and do not justify added code complexity.
