From 1606aab99bd84f0040fb0fa6ccccb092941f01ec Mon Sep 17 00:00:00 2001 From: Paul B Mahol Date: Fri, 1 Dec 2023 16:59:07 +0100 Subject: [PATCH] avfilter/avfilter: fix OOM case for default activate Fixes OOM when caller keeps adding frames into filtergraph that reached EOF by other means, for example EOF is signalled by other filter in filtergraph or by buffersink.
