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). Graphics API: Khronos OpenGL ES, Microsoft DirectX 11 Compute API: OpenCL, Renderscript Compute and Direct Compute. After this overview, he starts to talk about Midgard architecture and gives the …

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 …

DLNA/UPnP Linux Server with Coherence

Coherence is a DLNA/UPnP Media Server written in Python which exports local files or online media to UPnP clients. Coherence fetch the media files from several sources such as: Local applications media collections, like those from Rythmbox or Banschee, Audio-CD or DVB Online services like Flickr, last.fm, YouTube, Picasa Web Albums and other. Other sources can also be added thanks to Coherence plug-in architecture. The media server supports transcoding (currently experimental) that is to convert media files in another format. Coherence toolkit also contains other packages such as: Coherence-Config: a cross-platform GUI frontend for ‘Coherence’. Cadre: a picture DLNA/UPnP MediaRenderer which can display pictures from the local filesystem or from a MediaServer. Mirabeau: An application level proxy for UPnP devices which allows to share your UPnP content between two or more local networks over the Internet. It uses XMPP as a transport (work in progress). UPnP-Inspector:  a graphical UPnP Device and Service analyzer, and a debugging tool. Detected devices are …

Enable OpenGL 2.0 and WebGL for Intel GMA3150 in Ubuntu

I wanted to use WebGL in my Acer Aspire One D255E netbook that uses an Intel GMA 3150 onboard graphics card, but it did not work in Chromium nor Firefox. WebGL requires OpenGL 2.0 support, but I found out I only had support for OpenGL 1.4: But I found out it was possible to enable OpenGL 2.0 for GMA 3150 in Linux by installing and running driconf: and clicking on “Enable limited ARB_fragment_shader support on 915/945.” and “Enable stub ARB_occlusion_query support on 915/945.” options. They are not enabled by default because they do cause problems. After those two options were enabled, OpenGL 2.0 was enabled. But I still could not use WebGL in either Chromium nor Firefox, so I decided to install the latest version of Mesa (7.11) with indirect rendering (software) enabled with libOSMesa: Even with the latest Mesa library, I could not use WebGL applications, so I enabled software rendering in Firefox as follows: Type about:config in the …

OpenMAX (Open Media Acceleration)

OpenMAX (Open Media Acceleration) is a royalty-free, cross-platform set of C-language programming interfaces that provides abstractions for routines especially useful for audio, video, and still images. OpenMAX standard is managed by the non-profit technology consortium Khronos Group. OpenMAX allows developers to take advantages of hardware media decoding/encoding. For example, If you want to play video using Raspberry Pi hardware (VideoCore IV GPU in Broadcom BCM2835) you’ll have to use OpenMAX IL. OpenMAX provides three layers of interfaces: Application Layer (AL): Open standard for accelerating the capture, and presentation of audio, video, and images in multimedia applications on embedded and mobile devices. Integration Layer (IL) : API defining a standardized media component interface to enable developers and platform providers to integrate and communicate with multimedia codecs implemented in hardware or software. Development Layer (DL): APIs containing a comprehensive set of audio, video and imaging functions that can be implemented and optimized on new CPUs , hardware engines, and DSPs and then …

Android Platform Optimizations – ELCE 2011

Ruud Derwig and Mischa Jonker, both working at Synopsys, present different Android optimization methods at Embedded Linux Conference Europe 2011. Abstract: Although compute platforms gain performance with every new generation, getting the most out of every cycle and milliwatt remains a key value driver for Consumer Electronics. This presentation opens up the Android platform and explain what platform components and frameworks can benefit from performance optimizations. The optimizations are illustrated using real-life examples from the porting and optimization of the Android platform for the DesignWare ARC CPU. Both Android platform and application developers will gain insight in how to improve Android performance. Topics that are addressed include the Pixelflinger, Linux kernel and drivers, Javascript engine, Bionic C library, and the Dalvik VM. We’ll demonstrate the portability of Android and suitability of the ARC architecture for building efficiently Android systems. You can also download the presentation slides. Jean-Luc Aufranc (CNXSoft)Jean-Luc started CNX Software in 2010 as a part-time endeavor, before quitting …
