桌面上总是会自动生成dxva_sig为名的记事本
dxva_sig之谜
最近总在桌面上无缘无故的出现一个“dxva_sig.txt”的文本文件,我都怀疑是病毒了。上网搜索原来不是。这是因为DirectX Video Acceleration (DXVA)针对WM10编码问题引起的。
微软对于解决方案的描述:
This update enables Microsoft DirectX Video Acceleration (DXVA) of Microsoft Windows Media Video (WMV) content in Microsoft Windows Media Player 10 for video cards when the drivers of those video cards are designed to take advantage of this feature.
