从 VLC 和 SMPlayer 到 Chrome，我每天都会遇到视频播放问题，甚至每小时都会遇到一次。首先，请看一下这个在 Chrome 中以全屏模式播放的 YouTube 视频，当我退出全屏模式时，一切都冻结了：
下面是另一个视频，显示当我移动 SMPlayer 的窗口时，视频区域稍微滞后了一点：
我的系统规格是：
- 处理器：酷睿 i7 6700
- 显卡：集成显卡
- Ubuntu 15.10
我也安装了适用于 Linux 的英特尔® 显卡。
有什么方法可以解决这些问题吗？
编辑：当我在详细模式下运行 VLC 时，我在日志输出中收到以下消息：

编辑 2：我安装libvdpau_va_gl并删除~/.config/vlc以重置 VLC 的配置，现在我在日志输出中收到这些错误：

在 SMPlayer 中：选项->首选项->视频选择除 xv 之外的输出驱动程序。例如：gl。然后尝试再次播放您的视频。希望对您有所帮助）
在 VLC 中：工具->首选项->视频取消选中加速视频输出（覆盖）
