使用带有视频加速 (VA) 的 nvidia 驱动程序时出现“失败请求的 X 错误：BadRequest”

我想简单地展示一个使用 gstreamer-1.0 的测试源。当我使用（我猜）非加速输出时，gst-launch-1.0 videotestsrc ! xvimagesink一切都正常，但当我尝试播放它时，gst-launch-1.0 videotestsrc ! autovideosink我收到以下错误：

Setting pipeline to PAUSED ...
libva info: VA-API version 0.35.0
X Error of failed request:  BadRequest (invalid request code or no such operation)
  Major opcode of failed request:  153 (DRI2)
  Minor opcode of failed request:  1 (DRI2Connect)
  Serial number of failed request:  15
  Current serial number in output stream:  15

我已安装NVIDIA-Linux-x86_64-367.44.run如下Ubuntu 14.04.5：

  1. 删除旧驱动程序：sudo apt-get remove --purge nvidia*
  2. 通过运行脚本将旧驱动程序列入黑名单（它会要求你这样做，然后退出）
  3. 重启
  4. 停止服务：service lightdm stop && service x11-common stop
  5. 安装驱动程序：./NVIDIA-Linux-x86_64-367.44.run --no-x-check
  6. 已安装 VA 相关内容https://wiki.ubuntuusers.de/Video-Dekodierung_beschleunigen/：sudo apt-get install libvdpau1 vdpauinfo vdpau-va-driver vainfo
  7. 重启

以下是一些有用的输出，但仍会产生错误：

有人能提供提示吗？我知道按照说明操作后这台电脑曾经能用，但现在好像出了点问题。

通过将所有内容恢复为原始 Ubuntu 来修复它，但视频加速仍然不起作用：

  1. 删除前任司机：sudo ./NVIDIA-Linux-x86_64-xxx.xx.run --uninstall
  2. 卸载与 nvidia 相关（通过 搜索相关软件包dpkg -l）：nvidia、cuda、primus、vdpau-va-driver、vainfo、libvdpau1、vdpauinfo
  3. 删除 nouveau 驱动程序的所有黑名单内容：删除/etc/modprobe.d
  4. 通过以下方式恢复 xconfig：sudo X -configure && sudo cp xorg.conf.new /etc/X11/xorg.conf
  5. 重新安装mesa-vdpau-drivers-lts-<your release>
  6. 重要的：删除 gstreamer vaapi，以便它在使用类似autoconvert或autovideosink的插件时不会尝试使用加速：sudo apt-get remove gstreamer1.0-vaapi gstreamer1.0-vaapi-doc libgstreamer-vaapi1.0-0:amd64 libgstreamer-vaapi1.0-dev

现在，测试程序glxinfo再次glxgears按预期运行。

无论如何：失败的尝试：我仍然不知道为什么即使使用官方 ppa，VA 东西也无法与原始驱动程序一起工作：

sudo add-apt-repository ppa:graphics-drivers/ppa
sudo apt-get update
sudo apt-get install --install-suggests nvidia-340

glxinfo并glxgears正常工作，但vainfo仍然vdpauinfo输出错误。我设法vdpauinfo通过使用驱动程序和导出来输出错误以外的内容mesa（如果变量指向专有驱动程序，它将不起作用）：

export VDPAU_DRIVER_PATH=/usr/lib/x86_64-linux-gnu/vdpau/
export VDPAU_DRIVER=va_gl

但这只是显示驱动程序，对吧。所以我需要告诉 VA API，它必须vdpau像这样使用（？）：

export LIBVA_DRIVERS_PATH=/usr/lib/x86_64-linux-gnu/dri/
export LIBVA_DRIVER_NAME=vdpau

但在那种情况下，vainfo无论我选择哪个驱动程序名称，都只会回复错误。

如果有人知道如何使其工作，请帮忙。 但目前，gstreamer 可以再次运行（但 CPU 负载较高）。
