当尝试在装有 Nvidia 显卡驱动程序的兼容 vdpau 的笔记本电脑上运行带有 vdpau 的 mplayer2 时，我只能从中获得音频。
我的 Nvidia 卡应该据我所知，它不受支持，所以我想知道问题是否在于我没有正确的包或配置：

答案1
根据您问题中发布的信息，您有一个同时使用 Intel + Nvidia 的混合 GPU 解决方案。
要启用您的 Nvidia 卡，您需要安装 Bumblebee 或在 BIOS 中禁用 Intel 卡（如果可能）。
如果无法在计算机的 BIOS 中禁用英特尔卡，则您除了使用 Bumblebee 之外别无选择。
如果你需要有关 Bumblebee 的信息，请查看这篇文章，它详细说明了如何启用支持以在同时激活 Intel 和 Nvidia 卡的情况下运行 Ubuntu
如果您已经在使用 Bumblebee，这并不意味着已安装 vdpau 支持，您需要按照此处所述为您的卡安装 vdpau 支持
在您成功管理运行之后，运行大黄蜂vainfo仍然会失败，因为英特尔卡仍然是默认卡。
我已经发现脚本这会将显卡从 Intel 切换到 Nvidia，并尝试打开媒体播放器。使用此功能的基本说明如下这里，请记住这是一个来自外部来源的脚本，不保证它会起作用，您可以自己测试。
以下是从错误报告中获取的说明：
构建 hybrid-windump 但不要使用包含的 xorg.conf！ https://github.com/harp1n/hybrid-windump（包括整个转储窗口的边框） https://github.com/gebart/hybrid-windump（包括更好的光标支持，但转储窗口将覆盖英特尔桌面的一部分并且无法移动）
启动 Bumblebee X 服务器 optirun glxinfo
在 Nvidia 显示器上运行 Compiz（或 Metacity），以便转储窗口可以移动。如果跳过此步骤，VDPAU 播放将为绿色。DISPLAY=:8 compiz --replace &
运行 mplayer2 DISPLAY=:8 mplayer -vo vdpau videofilename &
转储窗口 ./windump :8 :0.0 &
您现在有了 VDPAU 输出！
注意：这也适用于 Ironhide。
