From 6b0c94780d8087772a718bfa8fdcb46b1770b987 Mon Sep 17 00:00:00 2001 From: Andreas Rheinhardt Date: Fri, 17 Apr 2020 15:55:57 +0200 Subject: [PATCH] libavcodec/avpacket: Don't simply forward return value of av_dict_set() The documentation of av_dict_set() states that values >= 0 indicate success, whereas av_packet_unpack_dictionary() implies that return values > 0 are impossible. So only forward the return value of av_dict_set() in av_packet_unpack_dictionary() on error. (Btw: av_dict_set() does currently not return values > 0.)
