Cross-compiling libavg 1.7 for ARM on Debian

libavg is a high-level development platform for media-centric applications using Python as scripting language and written in C++ and I’ve already written a post to cross-compile libavg 1.6 in Ubuntu (with linaro cross toolchain) and using Beagleboard qemu image. Since I’ve doing some preparation work to have software running on the Raspberry Pi and that the latter won’t support Ubuntu, I’ve had to cross-compile it again. This time, I’ve found a cleaner way to do the cross-compilation with dpkg-cross and xapt tools which can load the required armel package to the arm toolchain. Those tools really make life easy, as previously (a few years ago), I would have had to cross-compile all dependencies manually. Here are the steps I followed: Install Emdebian ARM Cross Toolchain and Tools in Debian. Download libavg 1.7 source code Extract it Install the following armel development packages: sudo /usr/share/pdebuild-cross/xapt -a armel libpango1.0-dev libavformat-dev libavcodec-dev libswscale-dev python2.6-dev libboost-python-dev libboost-thread-dev libglu-dev libgl1-mesa-dev libgtk2.0-dev libglib2.0-dev libsdl-dev libxml2-dev libxxf86vm-dev …

20 Times More Graphics Performance with Imagination G6200 and G6400 PowerVR Series 6 GPU

Imagination Technologies announced the first two IP cores, namely PowerVR G6200 and G6400 GPU IP cores, part of PowerVR Series6 GPU cores. PowerVR Series6 relies on PowerVR Rogue architecture based on a scalable number of compute clusters and designed to target the requirements of new high-end graphics applications for smartphones, tablets, PC, console, automotive, DTV and more. The G6200 and G6400 have 2 and 4 compute clusters respectively. The company claims that PowerVR Series6 GPUs can deliver 20x or more of the performance of current generation GPU cores targeting comparable markets thanks to the new Rogue architecture that is around 5x more efficient than previous generations. The PowerVR Series6 GPU cores offer computing performance exceeding 100GFLOPS (gigaFLOPS) and reaching the TFLOPS (teraFLOPS) range. The PowerVR Series6 family introduces new technologies and features such as: An advanced scalable compute cluster architecture. High efficiency compression technology including lossless image and parameter compression as well as PVRTC texture compression. An enhanced scheduling architecture …

Graphics Hardware Acceleration for Android 4.0 on Origen and Snowball Development Boards

Last week, Linaro Android team announced that graphics hardware acceleration (2D and 3D) was coming to Android 4.0 for ST Ericsson Nova A9500 Snowball and Samsung Exynos 4210 Origen development boards. They have now release 2 videos to show the progress on the implementation. The first video (around 5 minutes) showcases Samsung Origen development board running Linaro’s build of Android ICS with 2D and 3D demo. The second video (1:21) shows 2D hardware acceleration on ST Ericsson Snowball board. Snowball Android 4.0 daily snapshots and instructions are available at https://android-build.linaro.org/builds/~linaro-android/staging-snowball/ and Origen builds at https://android-build.linaro.org/builds/~linaro-android/staging-origen/ The official December 2011 releases should also come pretty soon are available at http://releases.linaro.org/11.12/android/. Jean-Luc Aufranc (CNXSoft)Jean-Luc started CNX Software in 2010 as a part-time endeavor, before quitting his job as a software engineering manager, and starting to write daily news, and reviews full time later in 2011. www.cnx-software.com Support CNX Software – Donate via PayPal or become a Patron on Patreon

Dual Monitor Setup with ATI Graphics Cards in Ubuntu

I’ve recently bought an ATI Radeon HD5450 in order to be able to use multiple displays in Windows XP and Ubuntu 11.04. I’ll explain how to install and configure the ATI drivers in order to use multiple displays and extend the desktop on two monitors. The first thing to do is to install the proprietary ATI drivers and Catalyst Control Center. Click on the icon at the top right of the screen and select “System Settings” in the drop down menu. Then click on “Additional Drivers”, Ubuntu should detect your ATI graphics card automatically and show the following: Click on “Activate” to download and install ATI/AMD proprietary FGLRX graphics driver and Catalyst Control Center (CCC). Alternatively, you could also download the latest linux ATI driver (version 11.12) on ATI website and run ./ati-driver-installer-11-12-x86.x86_64.run After installation, you may have to restart you computer. Once the drivers are installed, if you use a HDTV connected via HDMI  as a second monitor you …

Ubuntu Smartphone and Television UI Mockups

Ubuntu developers announced they wanted to port their OS beyond desktop by 2014, and would like to use it on smartphones, tablets and televisions. Following the announcement, the community has made a few mockup. Here are a few samples: Unity Mobil Mockup by JMMING: I quite like this design (Samsung Nexus Series U) similar to Android with the Ubuntu theme. My Ubuntu Phone by Musl1m: muls1m mockup is also based an icon grid, but keeps the Ubuntu icon bar on the left.  Ubuntu with mobile Unity by ginjaninja405 This mockup is similar to the one above, but the icon bar can be located either to the left or to the right, and  the bottom image shows phone related notifications such as missed phone calls, SMS and Facebook messages and notifications. There are also other interesting Ubuntu smartphones mockup, including a full phone design (casing + UI) based on Ubuntu theme. If you are interested you can check out: Ubuntu phone by …

Metaio Releases Mobile Augmented Reality SDK

Yesterday Qualcomm released QCAR SDK 1.5 Beta, and today Metaio announces its Mobile SDK 3.0 for augmented reality application development on Android and iOS. The metaio Mobile SDK brings with it patented gravity-awareness and visual tracking technology for 2D and 3D objects, now three times more robust than the previous version. These features combined will ensure AR experiences that are more natural, more intuitive, and more realistic, says the company. Metaio recently announced formal collaborations with ARM, ST-Ericsson and Texas Instruments to fully take advantage of the GPU hardware provided by those companies and the Mobile SDK is optimized for ARM Mali GPU (both graphics and compute), ST Ericsson Nova and NovaThor mobile processors and TI OMAP processors. The metaio Mobile SDK also includes its own 3D rendering engine – now with advanced shader support – and a plugin to make use of Unity3D (3D game engine). You can watch Metaio Mobile SDK 3.0 promotion video below The free Mobile …

Midgard architecture for Embedded GPUs (Mali-T604 / Mali T658)

I’ve attended a webinar entitled “Harness the power and flexibility of the Midgard architecture for Embedded GPUs” presented Steve Steele, Product Manager at ARM Media Processing Division and sponsored by EETimes. Steve starts to talk about the current GPU architecture “Utgard” used in Mali-200, Mali-300 and Mali-400MP which allows resolutions up to 1080p and are used in many smartphones today including Samsung Galaxy S2 (Mali-400MP) which provides great graphics performance. He then explains how mobile devices are used today and what performance we may except in the future: Mobile As Main compute platform: New UI and Augmented Reality Social Networks and emails Content Creation/consumption 1 Device to multiple screen (e.g LCD screen and TV via HDMI) Evolving Processing Demand: Graphics Complexity multiplied by 25 Increase in screen size (1080p resolution support).

WebP Image Format Could Replace JPEG, PNG and GIF

In September 2010, Google announced the WebP image format with lossy compression.  Since last month, WebP can also support animation, ICC profile, XMP metadata and tiling. Today, it announced lossless compression and transparency support. WebP could be used as an alternative to JPEG, with 25–34% better compression compared to JPEG images at equivalent SSIM index as well as PNG as it now supports lossless compression and transparency – also known as alpha channel – in both the lossless and lossy modes. On average, Google got a 45% reduction in size when starting with PNGs found on the web, and a 28% reduction in size compared to PNGs that are re-compressed with pngcrush and pngout. Photos typically encoded as JPEG can be encoded in WebP lossy mode to achieve smaller file size. Icons and graphics can be encoded better in WebP lossless mode than in PNG. WebP lossy with alpha can be used to create transparent images that have minimal visual …
