Handbrake 0.10 Supports H.265 and VP8 Video Encoding

HandBrake is an open-source video transcoding tool that I use each time I upload a video on YouTube, simply because it will let me crop the beginning or end of a video as needed, can make web optimized videos, has an easy to use user interface, and greatly reduces the size of the video shot with my camera. HandBrake 0.10 has now been released, and it adds H.265 and VP8 encoding support via respectively x265 v1.4 and linbpx, as well as QuickSync video support, but the latter only in Windows. There are also various other changes include OpenCL accelerated scaling. Handbrake is available for Windows, Mac OS X, and Ubuntu operating systems. It’s part of Ubuntu repository, but if you want the latest version, and support for MPEG-4 (m4v), you’ll need to install it from a PPA:

sudo apt-add-repository ppa:stebbins/handbrake-releases
sudo apt-get update
sudo apt-get install handbrake-gtk

sudo apt-add-repository ppa:stebbins/handbrake-releases

sudo apt-get update

sudo apt-get install handbrake-gtk

I’ve tested with the video I shot yesterday, to see if I […]

ODROID-XU3 Lite Development Board – Android Setup and Benchmarks

It’s been nearly ten days since I make ODROID-XU3 Lite unboxing, and my plans to first test Linux on the board were thwarted due a problem with HDMI. Luckily, after several attempts I managed to boot the board with Android. So today, I’ll show how to install or update Android on the board, and run a few benchmarks. But since there’s always a silver lining, I’ll start buy writing a bit about the HDMI issue, as I learned a few things on the way. HDMI Output Tribulations ODROID-XU3 Lite looks like a nice and powerful kit, and it may be one of the most cost effective ARM board on the market since it comes to performance to price ratio, so I was excited to try it, but as you know if you’ve read my unboxing post I did not work quite as planned, as all I got was a black […]

How-to Install Ubuntu on Allwinner A80 Powered pcDuino8 and A80 OptimusBoard

Last month, pcDuino released Android 4.4 and Ubuntu images for pcDuino8 board powered by Allwinner A80 octa core processor, and since it’s the same board layout as A80 OptimusBoard, I decided to try it out, but it failed as the update script would try to flash it to a partition that’s too small for the root file systems. But last week, Ian Morrison and Minidodes gave it another try, and successfully booted Ubuntu, or more exactly Lubuntu, on A80 OptimusBoard. Both their screenshot reports sun9i platform in /proc/cpuinfo, so that’s definitely Allwinner A80, but only one core is shown. I’m not sure if it’s because the other are idled and don’t show, or for some reasons, the kernel only supports one core at this stage. Anyway, here’s how they did to install Lubuntu: Flash the kernel (pcduino8_kernel_livesuit_20141008.img) with PhoenixCard or Livesuit first. See instructions to use Livesuit with A80 OptimusBoard.

Zsun SD111 Is Now “Officially” an Hackable Wireless Flash Drive

Zsun SD11x are Wi-Fi flash drives for 8 to 128 GB eMMC, alternative to Sandisk or Kingston. Yesterday, I soldered the UART pins to Zsun SD111 (8GB) flash drive to access the serial console, but I did not manage to enter the terminal as it was password-protected. I posted my results anyway, as I was convinced I would get some clever ideas from my readers, some of which appeared to be a little time consuming, but Zoobab offered a simple solution that consisted in changing the boot parameters, by replacing /sbin/init by /bin/sh. The first step is to interrupt the boot by pressing space or another key, in order to access U-boot. Now we can check the U-boot environment ar7240> printenv bootargs=console=ttyS0,115200 root=31:02 rootfstype=jffs2 rw init=/sbin/init mtdparts=ar7240-nor0:64k(u-boot),64k(u-boot-env),6720k(rootfs),1216k(uImage),64k(NVRAM),64k(ART) bootcmd=bootm 0x9f6B0000 bootdelay=4 baudrate=115200 ethaddr=0x00:0xaa:0xbb:0xcc:0xdd:0xee ipaddr=10.168.168.1 serverip=10.168.168.10 stdin=serial stdout=serial stderr=serial ethact=eth0 Environment size: 361/65532 bytes Let’s keep everything the same, except the init, […]

How to Flash Firmware to Realtek RTD1195 Media Players

Android TV boxes based on Realtek RTD1195 SoC are cheap (about $60), with a relatively slow dual core Cortex A7 processor, but include fast interfaces such as USB 3.0, Gigabit Ethernet, and sometimes SATA, and are said to be very good at playing videos. After several months of development since they’ve first been spotted, RTD1195 media player are finally shipping. One of the models is M-195, which had its firmware recently released, and can be downloaded from copy.com, filefactory, mediafire, or solidfiles servers. This firmware is based on Android KitKat 4.4.2, with build number rtk-phonenix-eng 4.4 krt160 eng.ton.20141024.094201. Firmware update is pretty easy, and is operating system agnostic, since all you need to do is to basically copy the firmware file to a USB flash drive. A PC is not even necessary, as you can download the file and extract it directly from the mini PC itself. The same procedure […]

Beyond Debug Key Enables JTAG & UART Debugging, Supports OpenOCD

Beyond Semiconductor, a fabless semiconductor company based in Slovenia which develops their own 32-bit BA2x IP cores, has sent me one of their development tool, namely Beyond Debug Key supporting JTAG and UART interfaces either with BeyondStudio for the company’s BA2x processor, or the open source suite OpenOCD for other processors. Since I don’t have any Beyond Semi boards, I instead configured it, and quickly tried it with Atmel SAMA5D3 Xplained ARM Cortex A5 development board, and OpenOCD (Open On-Chip Debugger). The debug tool comes in the package above describing the key features of the kit: Performance Transfer rate in excess of 600 kB/s 30 MHz maximum JTAG clock Less than 20 μW power draw from target board Compatibility Fully compatible with Beyond BA2x processor family Access any 8-bit, 16-bit, 32-bit or 64-bit processors via JTAG Works with all JTAG compliant devices Software Support OpenOCD for access to a range […]

Add GPIOs to Windows, Linux, Android Computers and Devices with FTDI USB Adapters / Breakout Boards

It’s possible to to add GPIOs to your computer, (openWRT) router, or Android tablet using some FTDI USB dongles that expose I/Os. On operating systems based on Linux, including Android, you can use the GPIO sysfs interface (/sys/class/gpio) to easily control GPIOs from the command line, and in some cases Rx, Tx, CTS, .. pins can also be used as GPIOs. Zoobab has tried it with various FTDI USB adapters, and Oneping OP-1010 breakout board based on PL2303 HDX chip, and the results are mixed, but it could worth a try. There are currently patchsets ([1] and [2]) awaiting acceptance to mainline kernel that will enable GPIO support for these USB devices, but in the meantime you need to patch the kernel yourself, and then enable the relevant options in the kernel config for example “USB_SERIAL_PL2303_GPIO” or “USB_SERIAL_FTDI_SIO_GPIO”. The first patch is for PL2303 chips, and the second for FT2xxx/FT4xxx […]

Updated Android 4.4 Beta and Ubuntu Images for pcDuino8 / A80 OptimusBoard Boards Released

pcDuino8 and A80 OptimusBoard are the only two Allwinner A80 development boards currently “somewhat” available, and albeit the PCB color is different, every else is basically identical, and pcDuino8 firmware should probably run on A80 OptimusBoard and vice versa. If you own any of these boards, you may interested in two images, one with Android 4.4 (beta), and one with Lubuntu, recently released by pcDuino / Linksprite. Android 4.4 (beta) 2014-10-08 – sun9iw1p1_android_optimus.img to be flashed with PhoenixCard (Windows) or Livesuit (Linux) Lubuntu 14.04? 2014-10-08 is comprised of two files: Kernel – pcduino8_kernel_livesuit_20141008.img to be flashed with PhoenixCard or Livesuit first. See instructions to use Livesuit with A80 OptimusBoard. Rootfs – pcduino8_ubuntu_20141008.rar. First extract the rar files to the root of an SD card or USB flash drive. There should be two files: pcduino8_ubuntu_20141008.img and update.sh. Now connect the mass storage device to pcDuino3 / A80 Optimusboard, and reboot the […]
