Faster H.265/HEVC Video Encoding with Nvidia GTX960 GPU and ffmpeg

H.265 promises the same video quality as H.264 when using half the bitrate, so you may have thought about converting your H.264 videos to H.265/HEVC in order to reduce the space used by your videos. However, if you’ve ever tried to transcoding videos with tools such as HandBrake, you’ll know the process can be painfully slow, and a single movie may take several hours even with a machine with a power processor. However, there’s a better and fster solution thanks to hardware accelerated encoding available in some Intel and Nvidia graphics cards. For this purpose, GearBest sent me Maxsun MS-GTX960 graphics card, a second generation Maxwell GPU, that supports H.265 accelerated video encoding and promised up to 500 fps video encoding. So I’ve put the graphics card to the test in a computer running Ubuntu 14.04, and reports some of my findings here. Similar instructions can also be followed in […]

Raspberry Pi Zero, C.H.I.P, and Orange Pi One Boards’ Features and Price Comparisons

With Raspberry Pi Zero, Next Thing C.H.I.P, and Orange Pi One, we now have have three ARM Linux development boards selling (now or soon) for less than $10 excluding shipping and taxes. So I’d think it would be interesting to compare the features of the boards, and prices for different use cases. The comparison table below shows the three boards features side-by-side with items highlighted in green for the best or extra features, and in red for the weakest. Some cells will have to be filled later as data is currently not available (marked TBD). Raspberry Pi Zero C.H.I.P Orange Pi One Processor Broadcom BCM2835 single core ARM11 processor @ 1GHz (~1250 DMIPS) Allwinner R8 Cortex A8 processor @ 1 GHz (2000 DMIPS) Allwinner H3 quad core Cortex A7 processor @ 1.2 GHz (4x 2280 DMIPS) GPU VideoCore IV ARM Mali-400 ARM Mali-400MP2 Video Decoding 1080p30 for H.264, MPEG2* and […]

Orange Pi One is a $10 Quad Core Board with Ethernet and HDMI

Until recently, Orange Pi PC was probably the most cost efficient ARM hardware, but with the launch of Raspberry Pi Zero, and to some extent C.H.I.P computer, they had some competitors in the ultra low cost space, so Shenzhen Xunlong Software developed two more cost effective Orange Pi boards, with Orange Pi One selling for $9.99 with Ethernet, and Orange Pi Lite for $12 with WiFi, also referred to as versions B and A. Orange Pi One & Lite (preliminary) Specifications: SoC – Allwinner H3 quad core Cortex A7 @ 1.2 GHz with an ARM Mali-400MP2 GPU up to 600 MHz System Memory – 512 MB DDR3 Storage – micro SD card slot Video & Audio Output – HDMI Connectivity Orange Pi One – 10/100M Ethernet Orange Pi Lite – WiFi USB Orange Pi One – 1x USB 2.0 host ports, 1x micro USB OTG port Orange Pi Lite – […]

ODROID-C2 Amlogic S905 Development Board is in the Works

Hardkernel ODROID-C1 and later ODROID-C1+ boards, both based on Amlogic S805 SoC, have been a popular alternatives to Raspberry Pi 2 board this year. But now that Amlogic S905 quad core 64-bit ARM Cortex A53 processor has been available for a few months, people have been wondering whether the Korean company would launch an Amlogic S905 board, and it looks like ODROID-C2 might not be too far off based on firmware files on odroid.in website. The firmware includes a device tree file, which combined with other files give some clues about ODROID-C2 specifications: SoC – Amlogic S905 quad core Cortex A53 processor @ up to 2.0 GHz with penta-core (3+2) Mali-450MP GPU System Memory – 1GB RAM (in doc), 2GB RAM (in Device tree) Storage – 1x micro SD card Video Output – 1x HDMI out USB – 1x USB hub, 1x USB OTG I don’t have much more information […]

CubieTruck Plus Development Board with DisplayPort & HDMI Sells for $84 (in China)

We first found out about CubieTruck Plus (aka Cubieboard 5) this summer, and while at the time we did not have the full details, it was clear from the board picture and name, that is was an update to CubieTruck board, replacing Allwinner A20 dual core processor by Allwinner A8 octa-core processor, and ditching the VGA port for DisplayPort while keeping most of the same features of the original version. The company has now provided more details while announcing the launch of the board in China, and it turns out CubieTruck Plus has a few more advantages, and at least one drawback. CubieTruck CubieTruck Plus SoC Allwinner A20 Allwinner H8 CPU Dual core Cortex A7 up to 1.08 GHz Octa core Cortex A7 up to 2.0 GHz GPU Mali-400MP2 PowerVR SGX544 up to 700 MHz Memory 2GB DDR3 Power [email protected] power jack Ethernet Gigabit Ethernet (RJ45) WiFi 802.11 b/g/n (2.4 […]

How to Resize Android’s Internal Storage Partition in Rockchip Devices

I installed Light Biz OS firmware on GeekBox yesterday, but I’ve quickly realized many applications such as Gimp Inkscape would not install due to the small 1.94GB “internal partition”, so I asked how to increase the partition size in GeekBox forums last evening, and got an answer overnight from “dewet”. The good news is that it worked so I’ll share the steps I followed in a computer running Ubuntu 14.04. It might also be possible to perform the same tasks within a Windows machine with Rorkchip’s Factory tools First let’s download the utils with relevant scripts and binaries:

git clone https://github.com/geekboxzone/utils
cd utils/rockdev

1 2	git clone https://github.com/geekboxzone/utils cd utils/rockdev

Now copy your device or board’s firmware file “update.img” to the working directory, and unpack it:

./unpack.sh update.img

1	./unpack.sh update.img

The output should look like:

How to Upgrade Rockchip Firmware in Linux for RK3288, RK3328, RK3368, RK3399, etc..

I’ve been looking for ways to upgrade firmware on Rockchip RK3368 based GeekBox in a computer running Ubuntu 14.04, but while they’ve provided firmware update instructions for Windows, which remains basically the same as upgrading firmware on Rockchip RK3288, there’s no such information for Linux. However, I could remember than Radxa Rock supported upgrade_tool utility, but since the tool linked on Radxa website might be outdated, I instead searched for some RKtools repository on Geekboxzone Github account, and I was lucky enough to find one. Here’s what I did to flash Light Biz OS to GeekBox with my Linux computer: Get the tools, and make sure upgrade_tool is there.

git clone https://github.com/geekboxzone/lollipop_RKTools.git
cd lollipop_RKTools/linux/Linux_Upgrade_Tool
unzip Linux_Upgrade_Tool_v1.23.zip 
cd Linux_Upgrade_Tool_v1.23/
ls -l upgrade_tool 
-rw-rw-r-- 1 jaufranc jaufranc 3013546 Dec 17  2014 upgrade_tool

git clone https://github.com/geekboxzone/lollipop_RKTools.git

cd lollipop_RKTools/linux/Linux_Upgrade_Tool

unzip Linux_Upgrade_Tool_v1.23.zip

cd Linux_Upgrade_Tool_v1.23/

ls -l upgrade_tool

-rw-rw-r-- 1 jaufranc jaufranc 3013546 Dec 17 2014 upgrade_tool

Download and extract the firmware, e.g. Cross_Lollipop_BizOS_V151208.7z:

sudo apt-get install p7zip-full
7z x Cross_Lollipop_BizOS_V151208.7z

1 2	sudo apt-get install p7zip-full 7z x Cross_Lollipop_BizOS_V151208.7z

Now connect a USB cable to the USB OTG port of your device or board. In case of GeekBox that’s the micro USB port. Now as the board is powered on, keep […]
