'X Error of failed request: BadRequest' when using nvidia driver with video acceleration (VA)

  • 772

I'd like to simply show a testsource using gstreamer-1.0. When I use (I guess) non-accelerated output gst-launch-1.0 videotestsrc ! xvimagesink everything works find, but when I try to play it like gst-launch-1.0 videotestsrc ! autovideosink I get the following error:

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

I've installed NVIDIA-Linux-x86_64-367.44.run on Ubuntu 14.04.5 as follows:

  1. Remove old drivers: sudo apt-get remove --purge nvidia*
  2. Blacklist the old driver by the run script (It asks you to do so, quit after it)
  3. Reboot
  4. Stop the services: service lightdm stop && service x11-common stop
  5. Install the driver: ./NVIDIA-Linux-x86_64-367.44.run --no-x-check
  6. Installed VA stuff concerning https://wiki.ubuntuusers.de/Video-Dekodierung_beschleunigen/: sudo apt-get install libvdpau1 vdpauinfo vdpau-va-driver vainfo
  7. Reboot

Here are some helpful outputs, which still deliver errors:

Does anybody have a hint? I know that it worked once with this PC following the instructions, but now something seems to be broken.

  1. Fixed it by reverting everything to stock ubuntu, but video acceleration does still not work:

    1. Remove former driver: sudo ./NVIDIA-Linux-x86_64-xxx.xx.run --uninstall
    2. uninstalling which was related to nvidia (search related packages by dpkg -l): nvidia, cuda, primus, vdpau-va-driver, vainfo, libvdpau1, vdpauinfo
    3. Remove all blacklist stuff for the nouveau drivers: Remove necessary files in /etc/modprobe.d
    4. Revert xconfig by: sudo X -configure && sudo cp xorg.conf.new /etc/X11/xorg.conf
    5. Reinstall mesa-vdpau-drivers-lts-<your release>
    6. IMPORTANT: Remove the gstreamer vaapi, so that it does not try to use the acceleration when plugins like autoconvertor autovideosink are used: sudo apt-get remove gstreamer1.0-vaapi gstreamer1.0-vaapi-doc libgstreamer-vaapi1.0-0:amd64 libgstreamer-vaapi1.0-dev

    Now, the test programs glxinfo and glxgears work again as expected.

    Anyway: The unsuccessful try: I still do not know why the VA stuff does not work with the original driver even when using the official ppa:

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

    glxinfo and glxgears works, but vainfo and vdpauinfo still output errors. I managed vdpauinfo to output something other than an error by using the mesa drivers and exporting (If the variables point to the proprietary driver, it wont work):

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

    But this is just the display driver, right. So I need to tell VA API, that it has to use vdpau like this (?):

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

    But in that case, vainfo only replies with errors, no matter which driver name I chose.

    If anyone knows how to make it work, please help. But for now, gstreamer works again (but with high CPU load).
