From 28c053ccaddb4d8afa8581023a9618c2679dd16c Mon Sep 17 00:00:00 2001 From: Yoann Lopes Date: Tue, 25 Sep 2012 16:58:44 +0200 Subject: Use QVideoWidget in the videowidget example. The videowidget example now uses QVideoWidget instead of a custom QAbstractVideoSurface, the former being the most straightforward and fastest way of showing a video in a QWidget. The old code has been moved to a new example: "customvideosurface".
