From 91a84a5247857d18b211f45129cf39b6788f0022 Mon Sep 17 00:00:00 2001 From: Anton Khirnov Date: Tue, 4 Sep 2012 22:01:38 +0200 Subject: af_asyncts: check return value from lavr when flushing. Fixes an infinite loop on flush when avresample_get_delay() still reports some samples but avresample_convert() doesn't return any data. --- libavfilter/af_asyncts.c | 9 +++++++-- 1 file changed, 7 insertions(+), 2 deletions(-) (limited to 'libavfilter/af_asyncts.c') diff --git a/libavfilter/af_asyncts.c b/libavfilter/af_asyncts.c index f5d2798b30..0b8be8d557 100644 --- a/libavfilter/af_asyncts.c +++ b/libavfilter/af_asyncts.c @@ -133,8 +133,13 @@ static int request_frame(AVFilterLink *link) nb_samples); if (!buf) return AVERROR(ENOMEM); - avresample_convert(s->avr, (void**)buf->extended_data, buf->linesize[0], - nb_samples, NULL, 0, 0); + ret = avresample_convert(s->avr, (void**)buf->extended_data, + buf->linesize[0], nb_samples, NULL, 0, 0); + if (ret <= 0) { + avfilter_unref_bufferp(&buf); + return (ret < 0) ? ret : AVERROR_EOF; + } + buf->pts = s->pts; return ff_filter_samples(link, buf); } -- cgit v1.2.3
