C.H.I.P Board and Allwinner A13/R8 SoCs To Get VPU Support in Linux Mainline

Allwinner has mixed relationships with open source communities such as Kodi, especially due to issues with its closed-source CedarX VPU drivers, and some GPL violations. However to address the former, linux-sunxi community has been working on open source Cedrus library for the video processor unit on Allwinner processors, that’s been successfully tested on boards such as Orange Pi One. Free Electrons has gone  further, as they’ve made sure Cedrus now works with Linux mainline kernel, currently Linux 4.8, and tested it on Allwinner R8 based Pocket CHIP. The work has been done by Florent Revest, a 19 years old intern at the company, who delivered a new sunxi-cedrus driver, a Video4Linux (V4L2) memory-to-memory decoder kernel driver, and corresponding VA-API backend, with the implementations currently available on Github here and there respectively. Currently only MPEG2 and MPEG4 are working, but adding other codecs such as H.264, and video encoding is possible […]

Broadlink MP1 is a $20 WiFi Power Strip with 4 Independent Sockets

There are plenty of WiFi sockets going around such as Broadlink SP2 or Kankun KK-SP3, but in some cases it might be both more convenient and cheaper to get a WiFi power strip, and Broadlink MP1 offers just that with 4 sockets that can be controlled and programmed (timer) independently, and sold for just $19.88 on Banggood. Broadlink MP1 specifications: Connectivity – 802.11b/g/n WiFi, controllable over 3G/4G with smartphone 4 multi-standard (EU/US/AU, but not UK) sockets Power input – 10A/250V (max) Power output – 10A/250V (max) Rated power – 2000W Total Misc – Power button Dimensions –  254mm x 60mm x 32mm; 50cm sockets spacing; cord Length – 1.5m with AU plug (Adapter provided for other countries) Weight – 450g The power strip can be controlled via Broadlink ihc (Intelligent Hone Control) app available for Android and iOS, which lets you independently manually turn on or off or set timers […]

Tanix TX5 Pro TV Box Review – Part 2: Modding and Testing

Karl here with part 2 of Tanix TX5 Pro TV box. In the first part we peaked inside took a look at the specs and quick look at the UI. In part 2, we will get into the nitty gritty. When I first received the box there were several issues: Play Store incompatibility, issue with language reverting to Chinese, and green screen on YouTube. Tanix quickly followed up with an update and resolved these issues. Stuck in my ways So I have to admit that I am pretty stuck in my ways when it comes to the way I use Android. It started long ago with my first stick the MK808 with Rockchip Rk3066. It was basically the phone version of Android on the TV and I really liked it. We have come a long way since then and some changes have occurred in the box market UI, like the […]

Amlogic S905, S905X, and S912 Processors Appear to be Limited to 1.5 GHz, not 2 GHz as Advertised

When I compared the performance Amlogic S905 and Rockchip RK3368 processors  last year, I noticed Amlogic S905 single thread performance not being much faster than the one of Rockchip RK3368, despite the former allegedly clocked at 2.0 GHz against the latter 1.2 GHz. But early this month one member (koschi) on ODROID forums started a thread entitled “No performance difference between 1.5, 1.75 & 2GHz” about ODROID-C2 board. The first post link to Ant-computing website about choosing a processor for a build farm, and one of the tables comparing various ARM and x86 processors with the claim that Amlogic S905 was listed to 1.536 GHz, because “the device claims to run at 2.016 GHz but the kernel silently ignores frequencies above 1.536 GHz!” So koschi did his own tests with 7z and sysbench, using cpufreq-set -u $FREQ to set a fixed frequency between test, and could confirm the issue:

Getting Started with ReSpeaker WiFi IoT Board’s Audio Capabilities, Voice Recognition and Synthesis

ReSpeaker is a development board combining an Atmel AVR MCU, a MediaTek MT7688 WiFi module running OpenWrt, a built-in microphone, an audio jack, and I/O headers to allow for voice control and output for IoT applications. That means you could make your own Amazon Echo like device with the board and add-ons, use it as a voice controlled home automation gateway and more. The board was launched on Kickstarter a few days ago, and already raised $100,000 from about 100 backers, but I’ve received an early sample, so I’ll provide some more information about the firmware, and shows how to use with some Python scripts leveraging Microsoft Bing Speech API. You’ll need a micro USB to USB cable to connect your to computer (Linux, Windows, Mac OS…), and a speaker to connect to the board. Linux (OpenWrt) boots in a few seconds, and once it’s done all RGB LED will […]

Ambarella A12S SoC Allows For Cheaper 4K 30 fps Action Cameras, or Does it Not?

[Update: I’ve been informed that Ambarella A12S product brief from their website contains outdated information, and that A12S does indeed support 4K @ 30 fps, not only 2K @ 30 fps] [Update 2 (03/09/2016): The company has now updated the page, and I’ve myself updated the article accordingly] Some ultra cheap Allwinner V3 based cameras are advertised as 4K cameras, but in reality they are limited to 4K @ 15 fps, and on top of that the software have to extrapolate data to get to that resolution. So there are not usable for most people, unless maybe if you somehow need a 4K CCTV camera. Currently one of the cheapest “true” 4K action cameras is Yi Technology / Xiaomi Yi 2 sports camera based on Ambarella A9S SoC, capable of recording up to 4K @ 30 fps, and selling for around $250. But there’s now a new wave of cheaper […]

VideoStrong KII Pro Android Set-top Box with DVB-T2 & DVB-S2 Tuners Comes with 2GB RAM

Based on the number of comments I get daily on my review of Videostrong K1 Plus T2 S2 Android TV box, the device is rather popular thanks to its dual DVB-T2/T2C and DVB-S2/S tuner, its low price, and OpenELEC community support. However, some people are possibly affected by the mere 1GB RAM in the system, with some apps being killed during use due to lack of memory. One solution is to purchase WeTek Play 2, but at $120 it’s in a different price range, and does not offer a dual tuner solution. But Videostrong has recently launched their KII Pro DVB T2+S2 model based on K1 Plus DVB T2+S2, but with 2GB RAM, 16GB storage, and 802.11ac WiFi. KII Pro specifications: SoC –  Amlogic S905 quad core ARM Cortex-A53 @ up to 2.0GHz with  penta-core Mali-450MP GPU @ 750 MHz System Memory – 2GB DDR3 Storage – 16GB eMMC flash + […]
