2019-07-29avfilter/fade: don't allow nb_frames == 0Gyan Doshi
In filter init, there's a division by nb_frames but value isn't checked.
2018-11-12avfilter/vf_fade: fix start/duration max valueMark Harris
A fade out (usually at the end of a video) can easily start beyond INT32_MAX (about 36 minutes). Regression since d40dc64173.
2016-11-13lavfi: split frame_count between input and output.Nicolas George
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.

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>
