切换DXVA硬解码，视频播放黑屏
版本 主干master版本，win7 x64
问题 用QtAV工程自带的player切换DXVA硬解码，播放器没有提示错误，但是在播放的时候一直黑屏

这里加黑的地方出现了错误，但是外面AVPlayer没有捕获这个错误的处理，能否在这里加入错误捕获，这样播放器可以和检测到硬解码不支持的情况下一样处理，切换回ffmpeg软解码进行播放
dxva失败会退回软解，https://github.com/wang-bin/QtAV/blob/master/src/codec/video/VideoDecoderFFmpegHW.cpp#L201
后面有什么log?

这里补充两个完整日志，一个是DXVA+FFmpeg，一个是CUDA+FFmpeg，我的电脑支持DXVA，但是不支持CUDA，CUDA这个逻辑工作良好，DXVA这个就切换软解码失败，黑屏 1. log-Player-DXVA+FFmpeg.txt http://paste.openstack.org/show/729017/ 2. log-Player-CUDA+FFmpeg.txt http://paste.openstack.org/show/729018/ 另外经过测试发现，视频是1k的时候，工作还比较正常，可以硬解码无需切换，2k和4k就有问题了，那个失败的函数和显存有关？分辨率大，显存不够，所以报错？ 我显卡是128M显存
同样存在问题，但使用qtav自带的player显示正常。加上这几行就正常播放了 a.setAttribute(Qt::AA_UseOpenGLES); qputenv("QT_OPENGL", "angle"); qputenv("QT_ANGLE_PLATFORM", "d3d9");
