From 6aaac24d72a7da631173209841a3944fcb4a3309 Mon Sep 17 00:00:00 2001 From: Ganesh Ajjanagadde Date: Sun, 4 Oct 2015 23:39:25 -0400 Subject: avfilter/all: propagate errors of functions from avfilter/formats MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Many of the functions from avfilter/formats can return errors, usually AVERROR(ENOMEM). This propagates the return values. All of these were found by using av_warn_unused_result, demonstrating its utility. Tested with FATE. I am least sure of the changes to avfilter/filtergraph, since I don't know what/how reduce_format is intended to behave and how it should react to errors. Fixes: CID 1325680, 1325679, 1325678.
