From 0ac8ff618c5e6d878c547a8877e714ed728950ce Mon Sep 17 00:00:00 2001 From: Luca Barbato Date: Tue, 28 Apr 2015 01:55:10 +0200 Subject: [PATCH] avresample: Reallocate the internal buffer to the correct size Fixes the corner case in which the internal buffer size is larger than input buffer provided and resizing it before moving the left over samples would make it write to now unallocated memory.
