From 465a72b4b4ad1366b47436506a1352ee0c0ef232 Mon Sep 17 00:00:00 2001 From: Stefano Sabatini Date: Sun, 10 Jun 2012 17:42:47 +0200 Subject: lavfi: move definition of avfilter_copy_buf_props() from buffer.c to avcodec.c avcodec.c is where it is defined the lavc/lavfi interface code, so seems a more adequate location (and doesn't force the inclusion of libavcodec/avcodec.h where it is not required). --- libavfilter/avcodec.c | 44 ++++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 44 insertions(+) (limited to 'libavfilter/avcodec.c') diff --git a/libavfilter/avcodec.c b/libavfilter/avcodec.c index 6d3aa59a80..6b23772564 100644 --- a/libavfilter/avcodec.c +++ b/libavfilter/avcodec.c @@ -79,6 +79,50 @@ AVFilterBufferRef *avfilter_get_audio_buffer_ref_from_frame(const AVFrame *frame return picref; } +int avfilter_copy_buf_props(AVFrame *dst, const AVFilterBufferRef *src) +{ + int planes, nb_channels; + + memcpy(dst->data, src->data, sizeof(dst->data)); + memcpy(dst->linesize, src->linesize, sizeof(dst->linesize)); + + dst->pts = src->pts; + dst->format = src->format; + + switch (src->type) { + case AVMEDIA_TYPE_VIDEO: + dst->width = src->video->w; + dst->height = src->video->h; + dst->sample_aspect_ratio = src->video->sample_aspect_ratio; + dst->interlaced_frame = src->video->interlaced; + dst->top_field_first = src->video->top_field_first; + dst->key_frame = src->video->key_frame; + dst->pict_type = src->video->pict_type; + break; + case AVMEDIA_TYPE_AUDIO: + nb_channels = av_get_channel_layout_nb_channels(src->audio->channel_layout); + planes = av_sample_fmt_is_planar(src->format) ? nb_channels : 1; + + if (planes > FF_ARRAY_ELEMS(dst->data)) { + dst->extended_data = av_mallocz(planes * sizeof(*dst->extended_data)); + if (!dst->extended_data) + return AVERROR(ENOMEM); + memcpy(dst->extended_data, src->extended_data, + planes * sizeof(dst->extended_data)); + } else + dst->extended_data = dst->data; + + dst->sample_rate = src->audio->sample_rate; + dst->channel_layout = src->audio->channel_layout; + dst->nb_samples = src->audio->nb_samples; + break; + default: + return AVERROR(EINVAL); + } + + return 0; +} + int avfilter_fill_frame_from_audio_buffer_ref(AVFrame *frame, const AVFilterBufferRef *samplesref) { -- cgit v1.2.3
