From c5432d3ca4af629cea713c7613d22f5c451d41ab Mon Sep 17 00:00:00 2001 From: Anton Khirnov Date: Thu, 10 May 2012 07:36:10 +0200 Subject: lavfi: move video-related functions to a separate file. This is easier to follow than having them randomly scattered in avfilter.c and defaults.c. --- libavfilter/avfilter.c | 184 ------------------------------------------------- 1 file changed, 184 deletions(-) (limited to 'libavfilter/avfilter.c') diff --git a/libavfilter/avfilter.c b/libavfilter/avfilter.c index 57108b13ce..9dacf70e22 100644 --- a/libavfilter/avfilter.c +++ b/libavfilter/avfilter.c @@ -248,35 +248,6 @@ static char *ff_get_ref_perms_string(char *buf, size_t buf_size, int perms) } #endif -static void ff_dlog_ref(void *ctx, AVFilterBufferRef *ref, int end) -{ - av_unused char buf[16]; - av_dlog(ctx, - "ref[%p buf:%p refcount:%d perms:%s data:%p linesize[%d, %d, %d, %d] pts:%"PRId64" pos:%"PRId64, - ref, ref->buf, ref->buf->refcount, ff_get_ref_perms_string(buf, sizeof(buf), ref->perms), ref->data[0], - ref->linesize[0], ref->linesize[1], ref->linesize[2], ref->linesize[3], - ref->pts, ref->pos); - - if (ref->video) { - av_dlog(ctx, " a:%d/%d s:%dx%d i:%c iskey:%d type:%c", - ref->video->pixel_aspect.num, ref->video->pixel_aspect.den, - ref->video->w, ref->video->h, - !ref->video->interlaced ?
