Adobe Flash Player Hardware Acceleration on Intel Graphics Cards

However, the open source AMD drivers should have built-in VDPAU support (you need Linux 3.10 and Mesa 9.2).</div><div style="text-align: justify;"><br /></div><div style="text-align: justify;">In my test (Ubuntu 13.10, Intel graphics), a full-screen 1080p flash YouTube video used around 160-170% CPU without libvdpau-va-gl and about 14-17% CPU when using libvdpau-va-gl. There were some occasional spikes when using libvdpau-va-gl, but usually it stayed around those values which is a really great improvement.<br /><br />Note:<b> I've tested this with Firefox and Chromium browsers with Adobe Flash Player 11.2 r202. It doesn't seem to work with Pepper Flash (available by default in Google Chrome)</b>. </div><div style="text-align: justify;"><br /></div><div style="text-align: justify;">libvdpau-va-gl is <b>work-in-progress</b> and while it has worked properly with Adobe Flash Player / Firefox on my system, it may not work properly for you or it may cause problems with other VDPAU-enabled applications and for this reason, it's advisable not to use this system-wide.</div><div style="text-align: justify;"><br /></div><div style="text-align: justify;"><b>Below you can watch a quick video demoing the CPU usage for a YouTube flash video, with and without libvdpau-va-gl:</b></div><br /><center><iframe allowfullscreen="" frameborder="0" height="360" src="//www.youtube.com/embed/ZUmwtx_HA8U" width="480"><br />(<a href="http://www.youtube.com/watch?v=ZUmwtx_HA8U">direct video link</a>; for more videos, subscribe to our <a href="http://www.youtube.com/user/nilarimogard">YouTube channel</a>)</iframe></center><br /><br /><br /><h2>Install and set up libvdpau-va-gl in Ubuntu</h2><br /><div style="text-align: justify;"><b>1.</b> Firstly, install the VAAPI drivers (for Intel HD Graphics as well as G45 and later)::</div><pre class="linux-code"><code>sudo apt-get install i965-va-driver</code></pre><br /><div style="text-align: justify;"><b>2.</b> Install libvdpau-va-gl by using the main WebUpd8 PPA (I've used Vincent Bernat's Debian <a href="http://packages.debian.org/sid/libs/libvdpau-va-gl1">packaging</a> - thanks!):</div><pre class="linux-code"><code>sudo add-apt-repository ppa:nilarimogard/webupd8<br />sudo apt-get update<br />sudo apt-get install libvdpau-va-gl1</code></pre><br /><div style="text-align: justify;"><b>3.</b> Adobe Flash doesn't use hardware acceleration by default on Linux so we'll have to force it:</div><pre class="linux-code"><code>sudo mkdir -p /etc/adobe<br />echo "EnableLinuxHWVideoDecode=1" | sudo tee /etc/adobe/mms.cfg<br />echo "OverrideGPUValidation=1" | sudo tee -a /etc/adobe/mms.cfg</code></pre><br /><b>4. </b>Like I was telling you above, it's not a good idea to enable libvdpau-va-gl system-wide yet. Instead, you can simply launch an application with "VDPAU_DRIVER=va_gl".<br /><br />Example: to launch Firefox with libvdpau-va-gl enabled, use:<br /><pre class="linux-code"><code>VDPAU_DRIVER=va_gl firefox</code></pre><br />To enable libvdpau-va-gl system-wide (not recommended for now because this may cause problems with some VDPAU-enabled applications), you need to open <i>/etc/X11/Xsession.d/20vdpau-va-gl</i> as root with a text editor and uncomment (remove the "#" in front of the lines) the last two lines. Or simply copy/paste the commands below:<br /><pre class="linux-code"><code>sudo sed -i "s/^# \[/\[/g" /etc/X11/Xsession.d/20vdpau-va-gl<br />sudo sed -i "s/^# export/ export/g" /etc/X11/Xsession.d/20vdpau-va-gl</code></pre><br /><b>5.</b> Optional: check if libvdpau-va-gl/VDPAU is working.<br /><br /><div style="text-align: justify;">You can check if libvdpau-va-gl is working and Adobe Flash Player uses hardware acceleration by right clicking a Flash video on YouTube and selecting "Stats for nerds". The stats box that shows up should display the following: "accelerated video rendering, accelerated video decoding", like in this <a href="http://dl.dropboxusercontent.com/u/1113424/img/flash-vdpau-intel.png">screenshot</a>.</div><br />Another way to check if libvdpau-va-gl/VDPAU is working propely, install vdpauinfo:<br /><pre class="linux-code"><code>sudo apt-get install vdpauinfo</code></pre><br />Then, run:<br /><pre class="linux-code"><code>VDPAU_DRIVER=va_gl vdpauinfo</code></pre><br /><div style="text-align: justify;">And you should get something like <a href="http://pastebin.com/raw.php?i=cwYQzGyk">THIS</a>. If you get an error (for example "Failed to open VDPAU backend"), either your graphics card doesn't support VA-API (since this VDPAU driver requires VA-API) or you've missed a step from the instructions above.</div><div style="text-align: justify;"><br /></div><br /><div style="text-align: justify;"><b>Arch Linux</b> users can install libvdpau-va-gl from <a href="https://aur.archlinux.org/packages/libvdpau-va-gl/">AUR</a>.</div><div style="text-align: justify;"><br /></div><div style="text-align: justify;"><b>For more information, source code or bug reports, see the libvdpau-va-gl <a href="https://github.com/i-rinat/libvdpau-va-gl">GitHub page</a>.</b></div>

Primus: Better Performance And Less Power Consumption For Bumblebee [Optimus Hybrid Graphics Chipsets]

<div style="text-align: justify;"><i>Nvidia Optimus is a technology used to increases battery life by switching between two graphics adapters (a low-performance integrated Intel graphics adapter and a high-performance one by Nvidia) within a computer system. Optimus GPU switching is officially only supported on Windows, but it's also unofficially available on Linux thanks to the Bumblebee project.</i></div><div style="text-align: justify;"><br /></div><div style="text-align: justify;"><b><a href="https://github.com/amonakov/primus">Primus</a> brings better performance and less power consumption when using <a href="http://www.bumblebee-project.org/">Bumblebee</a></b>, by replacing VirtualGL. According to the Bumblebee <a href="http://www.bumblebee-project.org/g+">G+</a> page, this has the following <b>advantages over the optirun (VirtualGL) solution</b> used by default in Bumblebee:</div><a name='more'></a><ul><li>Less overhead (better framerates) and cleaner solution (no networking or compression involved at all)</li><li>Fixes the "bug" that causes Bumblebee to shut down the GPU too early sometimes (no more need for the "optirun bash" workaround)</li><li>Less buggy/glitchy, easier to debug</li><li>Only uses/starts secondary GPU for OpenGL parts of applications - everything else remains on your main GPU (power savings)</li></ul><br />The Bumblebee developers explain what Primus does and the difference between Primus / optirun in simple terms in a comment on their G+ page:<br /><br /><blockquote>Bumblebee uses VirtualGL to copy the image generated by the second (faster) GPU to your display. VirtualGL was intended for use over a network though, so it takes a great many steps to enable this (compression, sending the image over a network link, decompression, etc).<br /><br />Primus doesn't perform all these "extra" steps, instead taking a more direct route (copying the rendered image in memory to the other GPU, then displaying there). In theory this should get you better performance as well as better compatibility. Running applications will "see" the OpenGL implementation of your real hardware, nothing virtual is presented to them.</blockquote><br /><div style="text-align: justify;">For comparison, here are the framerates I get on my laptop when using the integrated Intel graphics, when using the Nvidia graphics card using optirun and using primusrun (this is just for FPS and not an indicator for the whole performance!): </div><br /><table align="center" cellpadding="0" cellspacing="0" class="tr-caption-container" style="margin-left: auto; margin-right: auto; text-align: center;"><tbody><tr><td style="text-align: center;"><a href="http://netupd8.com/w8img2/glxspheres-regular.png" rel="image_group" style="margin-left: auto; margin-right: auto;" title="Using integrated (Intel) graphics"><img alt="glxspheres intel gpu" src="http://netupd8.com/w8img2/glxspheres-regular_thumb.png" /></a></td></tr><tr><td class="tr-caption" style="text-align: center;">Integrated (Intel) graphics</td></tr></tbody></table><br /><table align="center" cellpadding="0" cellspacing="0" class="tr-caption-container" style="margin-left: auto; margin-right: auto; text-align: center;"><tbody><tr><td style="text-align: center;"><a href="http://netupd8.com/w8img2/glxspheres-optirun.png" rel="image_group" style="margin-left: auto; margin-right: auto;" title="Using optirun (default in Bumblebee) with Nvidia GPU"><img alt="glxspheres optirun bumblebee" src="http://netupd8.com/w8img2/glxspheres-optirun_thumb.png" /></a></td></tr><tr><td class="tr-caption" style="text-align: center;">optirun (default in Bumblebee) using the Nvidia GPU</td></tr></tbody></table><br /><table align="center" cellpadding="0" cellspacing="0" class="tr-caption-container" style="margin-left: auto; margin-right: auto; text-align: center;"><tbody><tr><td style="text-align: center;"><a href="http://netupd8.com/w8img2/glxspheres-primus.png" rel="image_group" style="margin-left: auto; margin-right: auto;" title="Using Primus with Nvidia GPU - best performance of the 3"><img alt="glxspheres primusrun bumblebee" src="http://netupd8.com/w8img2/glxspheres-primus_thumb.png" /></a></td></tr><tr><td class="tr-caption" style="text-align: center;">Primus using the Nvidia GPU</td></tr></tbody></table><br /><div style="text-align: justify;">As you can see, the FPS using  Primus is a lot better than using the integrated graphics or using optirun with the Nvidia GPU.</div><div style="text-align: justify;"><br /></div><div style="text-align: justify;">Note: I've used "vblank_mode=0 primusrun" instead of simply running "primusrun" because that was recommended by the Primus GitHub page for benchmarking.
