From 71c644ceda80022c3f9e7dd23953e970968fa626 Mon Sep 17 00:00:00 2001 From: Stefano Sabatini Date: Fri, 16 Sep 2011 12:38:31 +0200 Subject: [PATCH] lavfi: set link audio time_base if not set in avfilter_config_links() The set value depends on the input link, or on the sample_rate value. Avoids the need to explicitely set the time_base value. --- libavfilter/avfilter.c | 5 +++++ 1 file changed, 5 insertions(+) diff --git a/libavfilter/avfilter.c b/libavfilter/avfilter.c index 78e91c8bf9..df1dd65b16 100644 --- a/libavfilter/avfilter.c +++ b/libavfilter/avfilter.c @@ -299,12 +299,17 @@ int avfilter_config_links(AVFilterContext *filter) if (link->src->input_count) { if (!link->sample_rate) link->sample_rate = link->src->inputs[0]->sample_rate; + if (!link->time_base.num && !link->time_base.den) + link->time_base = link->src->inputs[0]->time_base; } else if (!link->sample_rate) { av_log(link->src, AV_LOG_ERROR, "Audio source filters must set their output link's " "sample_rate\n"); return AVERROR(EINVAL); } + + if (!link->time_base.num && !link->time_base.den) + link->time_base = (AVRational) {1, link->sample_rate}; } if ((config_link = link->dstpad->config_props))
