Hello, I am collaborating with AMD to integrate and support AMF integration FFmpeg This patch solves issue with frame corruption if encoder connected directly to decoder Solution: storing frame reference while it is used during encoding From 0fae3679bae8e121ed7b997d7eabd533deb113fb Mon Sep 17 00:00:00 2001 From: Alexander Kravchenko <aakravchenko@luxoft.com> Date: Fri, 23 Mar 2018 12:50:21 +0300 Subject: [PATCH] AMF Encoder: fix issue with frame corruption if encoder connected directly to decoder.
