From 7e350379f87e7f74420b4813170fe808e2313911 Mon Sep 17 00:00:00 2001 From: Anton Khirnov Date: Wed, 28 Nov 2012 08:41:07 +0100 Subject: lavfi: switch to AVFrame. Deprecate AVFilterBuffer/AVFilterBufferRef and everything related to it and use AVFrame instead. --- libavfilter/vf_yadif.c | 65 +++++++++++++++++++++++--------------------------- 1 file changed, 30 insertions(+), 35 deletions(-) (limited to 'libavfilter/vf_yadif.c') diff --git a/libavfilter/vf_yadif.c b/libavfilter/vf_yadif.c index d1670902bb..37e9887421 100644 --- a/libavfilter/vf_yadif.c +++ b/libavfilter/vf_yadif.c @@ -31,8 +31,6 @@ #undef NDEBUG #include -#define PERM_RWP AV_PERM_WRITE | AV_PERM_PRESERVE | AV_PERM_REUSE - #define CHECK(j)\ { int score = FFABS(cur[mrefs + off_left + (j)] - cur[prefs + off_left - (j)])\ + FFABS(cur[mrefs +(j)] - cur[prefs -(j)])\ @@ -167,15 +165,15 @@ static void filter_edges_16bit(void *dst1, void *prev1, void *cur1, void *next1, FILTER(w - 3, w) } -static void filter(AVFilterContext *ctx, AVFilterBufferRef *dstpic, +static void filter(AVFilterContext *ctx, AVFrame *dstpic, int parity, int tff) { YADIFContext *yadif = ctx->priv; int y, i; for (i = 0; i < yadif->csp->nb_components; i++) { - int w = dstpic->video->w; - int h = dstpic->video->h; + int w = dstpic->width; + int h = dstpic->height; int refs = yadif->cur->linesize[i]; int df = (yadif->csp->comp[i].depth_minus1 + 8) / 8; int l_edge, l_edge_pix; @@ -225,23 +223,22 @@ static void filter(AVFilterContext *ctx, AVFilterBufferRef *dstpic, emms_c(); } -static AVFilterBufferRef *get_video_buffer(AVFilterLink *link, int perms, - int w, int h) +static AVFrame *get_video_buffer(AVFilterLink *link, int w, int h) { - AVFilterBufferRef *picref; + AVFrame *frame; int width = FFALIGN(w, 32); int height = FFALIGN(h + 2, 32); int i; - picref = ff_default_get_video_buffer(link, perms, width, height); + frame = ff_default_get_video_buffer(link, width, height); - picref->video->w = w; - picref->video->h = h; + frame->width = w; + frame->height = h; for (i = 0; i < 3; i++) - picref->data[i] += picref->linesize[i]; + frame->data[i] += frame->linesize[i]; - return picref; + return frame; } static int return_frame(AVFilterContext *ctx, int is_second) @@ -251,19 +248,19 @@ static int return_frame(AVFilterContext *ctx, int is_second) int tff, ret; if (yadif->parity == -1) { - tff = yadif->cur->video->interlaced ?
