From ef59cb0820c5542af9d62721a51c7f7256155069 Mon Sep 17 00:00:00 2001 From: Ilia Mirkin Date: Sun, 27 Nov 2016 01:15:03 -0500 Subject: [PATCH] swr: add streamout buffer offset into pBuffer pointer The buffer_size does not take the offset into account. Just add the offset into the pointer which lines up the structures much better.
