Gyan Doshi	43891ea8ab	avfilter/fade: don't allow nb_frames == 0 In filter init, there's a division by nb_frames but value isn't checked.	5 years ago
Mark Harris	ae4323548a	avfilter/vf_fade: fix start/duration max value A fade out (usually at the end of a video) can easily start beyond INT32_MAX (about 36 minutes). Regression since `d40dc64173`.	6 years ago
Martin Storsjö	8f5de34c8f	vf_fade: Make sure to not miss the last lines of a frame When slice_h is rounded up due to chroma subsampling, there's a risk that jobnr * slice_h exceeds frame->height. Prior to a638e9184d63, this wasn't an issue for the last slice of a frame, since slice_end was set to frame->height for the last slice. `a638e9184d` tried to fix the case where other slices than the last one would exceed frame->height (which can happen where the number of slices/threads is very large compared to the frame height). However, the fix in `a638e9184d` instead broke other cases, where slice_h * nb_threads < frame->height. Therefore, make sure the last slice always ends at frame->height.

Nicolas George	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.	8 years ago

Derek Buitenhuis	21f9468402	avutil: Rename FF_CEIL_COMPAT to AV_CEIL_COMPAT 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>	9 years ago

Clément Bœsch	50e66726a2	lavfi: use ceil right shift for chroma width/height. This should fix several issues with odd dimensions inputs. lut, vflip, pad and crop video filters also need to be checked for such issues. It's possible sws is also affected.	12 years ago
