From 29a8ed766354c45c9be4b8512c5b2eb25a450cdc Mon Sep 17 00:00:00 2001 From: Zhong Li Date: Wed, 4 Apr 2018 17:51:30 +0800 Subject: [PATCH] lavf/qsvvpp: bypass vpp if not needed. Currently vpp pipeline is always created, even for the unnecessary cases such as setting the option "vpp_qsv=w=1280:h=720" for an input with native resolution 1280x720. Thus introduces unnecessary performance dropping, so bypass vpp if not needed.
