From 5345965b3f088ad5acd5151bec421c97470675a4 Mon Sep 17 00:00:00 2001 From: Linjie Fu Date: Tue, 8 Oct 2019 21:41:02 +0800 Subject: lavc/qsvdec: Add GPU-accelerated memory copy support GPU copy enables or disables GPU accelerated copying between video and system memory. This may lead to a notable performance improvement. Memory must be sequent and aligned with 128x64.
