From 95bd9d58d8d37ddec8d37f5b35128689c0aa55a8 Mon Sep 17 00:00:00 2001 From: Yoann Lopes Date: Thu, 10 Sep 2015 18:25:37 +0200 Subject: DirectShow: use the EVR in the window control. Reuse existing code from the WMF plugin, which already uses the EVR. This enables HW-accelerated video decoding when using QMediaPlayer with a QVideoWidget.
