Qt Quick QML Digital Signage Demo Part 2

Following up on Qt Quick QML Digital Signage Demo Part 1, I’ve updated the digital signage demo to support the following: Play 5 videos in a loop Display 5 pictures in a loop where the picture is changed every 5 seconds Use a (twitter) RSS feed for the scrolling text I initially planned to use QML to list the media files, but it is apparently not possible without using C/C++ and I may do it later on. So instead, I hard-coded the video and picture playlists in the QML files with the ListModel element. Videos are located in the video directory and pictures in the pic folder. An index is needed to scroll thru the playlist, but QML does not support global variables, so I created a JavaScript file (globals.js) to store the video and picture index: // Global variables in JavaScript file var iVideoIndex = 0 var iPicIndex = […]

Qt Quick QML Digital Signage Demo Part 1

I’ve recently started to play around with Qt and since I’d like to do a digital signage player running on Raspberry Pi, I’ve decided to try to make a simple digital signage demo application to evaluate the development platform. In Part 1, my goal was to make a 3 zones layout with a video zone, a picture zone and a scrolling text zone. I would just play one hard-coded media in each zone and the video and scrolling text would have to continuously loop. I used Qt Creator to create a “Pigital Signage” application (or should it be Πgital Signage ?). To create the 3 zones I used the Gridview Element with 3 rectangles: Video zone: 600×432 Picture zone: 200×432 Text zone: 800×48 Displaying the image is very easy with the Image Element:

Image {
    source: "pic/phone.jpg"
}

Image {

source: "pic/phone.jpg"

}

The video playback was also supposed to be easy with the Video Element but it can […]

Renault R-Link In-Vehicle Infotainment System

During LeWeb 11 exhibition, Renault announced the R-Link, a 7″ touchscreen tablet that will equip Renault’s cars starting with the Zoe Electric car and the new Clio (Clio 4) in 2012 for a cost of between 500 to 1000 Euros. The R-Link features a 7″ resistive touchscreen display and comes with steering wheel-mounted controls and speech recognition to make sure the driver keeps an eye on the road. This tablet is said to be running a modified version version of Android 2.2 on a Texas Instruments ARM Cortex A8 processor clocked at 800 Mhz. Renault says the R-Link covers all the car’s functions and data while offering access to a menu of useful and community applications already available on Smartphone such as Tom Tom GPS, Emails, an application finding available parking (Apila), public transport routes (Metro), multimedia applications to play music & video and display picture… At the time of its […]

Mono for Android 4.0 (.NET Framework)

Xamarin has provided .NET support for Linux via the Mono project for a while. It has recently announced the availability of an Android 4.0 version of its Mono software in order to let .NET and C# developers use Microsoft Visual Studio to build Android applications. Mono for Android follows upon Xamarin’s MonoTouch framework for iOS (iPhone and iPad development) and consists of a plug-in for Microsoft Visual Studio, a core Mono runtime, a Software development and bindings for native Android APIs. Such software is designed to leverage existing .NET applications, libraries and tools for Android development. With Mono for Android, developers can also call upon their native skills in .NET and the C# programming language in developing Android apps. Xamarin says that Mono for Android 4.0 provides access to all the new features, native APIs and UI toolkits in Android 4.0. Mono for Android 4.0 brings those key improvements and […]

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 […]

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 […]
