From 183ce55b0de0a597b838d08bbac67f54c27ed42f Mon Sep 17 00:00:00 2001 From: Nicolas George Date: Tue, 30 Aug 2016 15:28:41 +0200 Subject: 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. --- libavfilter/vf_perspective.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'libavfilter/vf_perspective.c') diff --git a/libavfilter/vf_perspective.c b/libavfilter/vf_perspective.c index 287db68845..d590cfa48d 100644 --- a/libavfilter/vf_perspective.c +++ b/libavfilter/vf_perspective.c @@ -135,8 +135,8 @@ static int calc_persp_luts(AVFilterContext *ctx, AVFilterLink *inlink) double (*ref)[2] = s->ref; double values[VAR_VARS_NB] = { [VAR_W] = inlink->w, [VAR_H] = inlink->h, - [VAR_IN] = inlink->frame_count + 1, - [VAR_ON] = outlink->frame_count + 1 }; + [VAR_IN] = inlink->frame_count_out + 1, + [VAR_ON] = outlink->frame_count_in + 1 }; const int h = values[VAR_H]; const int w = values[VAR_W]; double x0, x1, x2, x3, x4, x5, x6, x7, x8, q; -- cgit v1.2.3
