For Ubuntu machine with NVIDIA graphics card, here’s how to implement hardware acceleration for video playback in Firefox web browser.

Firefox so far only supports VA-API for GPU decoding to offload CPU and save power. Both Intel and AMD GPUs support VA-API. However, NVIDIA so far supports the api only through the open-source Nouveau driver.

If you have only NVIDIA GPU running with proprietary driver, then hardware video acceleration does not work out-of-the-box for Firefox.

For choice, there are libvdpau-va-gl1 driver (h.264 only) or libva-vdpau-driver, but both seems no longer updated. The best choice so far is the free open-source nvidia vaapi driver.

This tutorial is going to show you how to enable hardware acceleration on Intel graphics cards using VDPAU driver.

VDPAU is an open-source library and API allows to video programs to offload portions of the video decoding process and video post-processing to the GPU video-hardware. If VDPAU available, CPU usage can be significantly lower.

Applications that uses VDPAU:

  • Avidemux as of version 2.6
  • Boxee
  • GStreamer
  • MPlayer
  • MythTV
  • XBMC Media Center
  • XBMC Live
  • Xine
  • MLT
  • Adobe Flash 10.2 Stage Video and later versions (32-bit only presently)
  • VLC media player 2.1

VDPAU is not available on Intel graphics cards. Fortunately, there’s an open-source project called libvdpau-va-gl, which is a VDPAU driver that uses OpenGL under the hood to accelerate drawing and scaling, and VA-API (if available) to accelerate video decoding. You can use it on some Intel chips.

Install libvdpau-va-gl via PPA on Ubuntu

Press Ctrl+Alt+T on your keyboard to open terminal. When it opens, run below commands one by one (Supports Ubuntu 13.10, 13.04, 12.10, 12.04).

sudo add-apt-repository ppa:nilarimogard/webupd8
sudo apt-get update
sudo apt-get install libvdpau-va-gl1

To install the VAAPI drivers for Intel HD Graphics:

sudo apt-get install i965-va-driver

To launch an application with the driver, for example, launch firefox:

VDPAU_DRIVER=va_gl firefox

To force Adobe Flash to use the hardware acceleration:

sudo mkdir -p /etc/adobe
echo "EnableLinuxHWVideoDecode=1" | sudo tee /etc/adobe/mms.cfg
echo "OverrideGPUValidation=1" | sudo tee -a /etc/adobe/mms.cfg

To enable the driver for system-wide (not recommended):

sudo sed -i "s/^# \[/\[/g" /etc/X11/Xsession.d/20vdpau-va-gl
sudo sed -i "s/^# export/ export/g" /etc/X11/Xsession.d/20vdpau-va-gl
