From 04d8700862851885ae5c164dac82d3e0c44965ab Mon Sep 17 00:00:00 2001 From: Marco Paniconi Date: Thu, 3 May 2018 19:42:08 -0700 Subject: [PATCH] vp9-svc: Add memset on the svc fb_idx. The memset is added to better handle frame drops with the GET_SVC_REF_FRAME_CONFIG contro There is an issue with some tests in bypass mode, so condition it on that for now.
