From: Andreas Rheinhardt Date: Wed, 24 Mar 2021 00:14:24 +0000 (+0100) Subject: avformat/utils: Remove redundant check X-Git-Url: https://git.sesse.net/?a=commitdiff_plain;h=63fcf3da018fd4c884d0780b90141ed22ed86016;p=ffmpeg avformat/utils: Remove redundant check This check is outdated because the caller doesn't need to check that the multiplication overflows when using av_realloc_array() (the code in question used av_realloc() before that); furthermore, the check is also a remnant of the time in which our allocation functions didn't use size_t parameters.
