libavg on Raspberry Pi

libavg development team has recently announced a beta port of their multimedia library to the Raspberry Pi. libavg is a high-level development platform for media-centric applications using Python as scripting language and written in C++. I came to know this platform as I tried Xibo Digital Signage, and I tested it on ARM platforms. Up to know this would only work using software rendering/decoding, and everything was painfully slow on ARM, but libavg developers are now making use of OpenGL ES to boost graphics speed. More work is needed, and they intend to eventually support features such as hardware video decoding (OpenMAX possibly via gstreamer) and compressed textures. Installing libavg on Raspberry Pi. Pre-built packages are available for Raspberry, so installation is pretty straight forward:

Running Samples Apps 32 samples are located in /usr/local/lib/python2.7/dist-packages/libavg/samples/ directory, and they rely on X11, so first start LXDE:

Open a serial console (LXTerminal) […]

SliTaz armhf: 46MB Linux Distribution for Raspberry Pi

SliTaz armhf is a minimal Linux distribution based on SliTaz Linux, that uses the hard-float ABI for the Raspberry Pi. The compressed SD card image is 46M, the rootfs 18.6 MB, and Slitaz uses just about 7 MB RAM after boot. Slitaz armhf rootfs comes pre-loaded with the following packages: busybox 1.20.2 dropbear 2012.55 – Light SSH client and server. nano 2.2.6 – GNU Nano Text Editor. retawq 0.2.6c –  Text mode Web browser. tazpkg 5.0 – SliTaz packages manager (Tiny autonomous zone packages manager). ytree 1.97 – file manager for file and archives. Slitaz armhf comes with tazpkg package manager which allows to install packages just like you would do with apt-get in Raspbian. There are over 3,300 packages available for Slitaz (x86), and for now, over 250 packages are available for Slitaz armhf. Let’s get try it out. First, download slitaz-armhf-mini-2012-12-14.zip, extract it, and copy it to an […]

YotaPhone Dual Display (LCD + E-Ink) Smartphone Hands-on Video

In the last few days, there has been a lot of buzz about the YotaPhone, an upcoming Russian Android 4.2 smartphone featuring Snapdragon MSM8960 dual core processor with 2 GB RAM and 32/64 GB Flash. But the real innovation is the presence of 2 full 4.3″ displays: a standard LCD display on one side, and an E-Ink display on the other. Here are the preliminary specifications of the YotaPhone: SoC – Qualcomm Snapdragon S4 MSM8960 dual core Krait processor @ 1.5 GHz System Memory – 2GB RAM Storage – 32 or 64 GB NAND Flash Display 4.3″ LCD Display (1280×720) 4.3″ E-Ink EPD display Camera – 12MP front camera Connectivity Wi-Fi (Direct) Bluetooth NFC 2G, 3G and 4G (LTE) mobile networks Audio – 3.5mm headphone jack Battery – 2100 mAh. The device supports wireless charging. Dimensions – 67 x 131 mm Weight – 140 grams You may think a smartphone […]

Running Ubuntu in Android with ODROID-X Development Board

I’ve had several people asking me about running Linux on Android in the last few months, but I did not look into it into details, because I thought we would just be able to run server apps. That is until Rohith left a comment on CNX Software Facebook timeline,  that it’s possible to run Linux in Android, and access the user interface via VNC (sort of simple, but I did not think of it). You probably need at least 1GB of memory and a multi-core processor to run this sort of setup correctly, so I finally decided to give it a try by running Ubuntu 12.04 with Unity interface in ODROID-X development board. I mainly followed the instructions available at http://linuxonandroid.org/ and inside the Android app. Most of the steps I followed can also be replicated on other rooted Android hardware platforms. Apart from Ubuntu 10.04 & 12.04, you can […]
