How to Download YouTube 4K Videos with Youtube-dl Script

Many Android devices can now support 4K VP9 and/or H.264 video decoding, but for some reasons, Google only serves 4K videos to devices running Android TV OS, as opposed to just Android, with the latter limited to 1080p videos. If for some reasons you want to watch a YouTube 4K video on a capable device, you could download it with youtube-dl script written in Python, and available for Linux, Windows, and Mac OS. I’ve been using the script for a while to download various video or audio files from YouTube, and other website, but for the purpose of this post, I made sure to update it to the latest version:

If you have already installed the script, it can also be updated with:

I’ll use one of the most popular 4K videos on YouTube as example, namely: COSTA RICA IN 4K 60fps (ULTRA HD) w/ Freefly Movi. The […]

Orange Pi One Development Board Sells for $3.69 Shipped (Promo)

[Update: Sorry the promo is over, and price is back at $13.79] Last time, we had a promo for Orange Pi PC for $8.57 on GearBest, and it was legit, but quantity limited, so not so easy to get. There’s now another promo from the same parent company, as Orange Pi One is sold for $3.69 including shipping on Everbuying with 289 pieces and about 8 days left. In case you can’t recall Orange Pi One specs, it’s a development board based on Allwinner H3 quad core Cortex A7 SoC, with 512 MB RAM, micro SD card for storage, 10/100M Ethernet,  a USB ports, and HDMI output. The best Linux OS for the board is probably Armbian. The normal price is around $13 to $14 shipped. Thanks to Theguyuk for the tip.

LibreELEC 8 for Intel Atom Bay Trail and Cherry Trail Devices with 32-bit UEFI Binary

LibreELEC, a fork of OpenELEC, was announced several months ago, and images for various hardware platform were released in that time period. However, support for Intel Bay Trail and Cherry Trail platforms using a 32-it UEFI binary might not have always work, or was more difficult to install. piotrasd has now created a LibreELEC 8 + Kodi 17 beta 3 build especially for this type of devices, and tested it on Tronsmart Ara IZ37 Bay Trail mini PC. However, it should work on other Intel Atom Z3735F or Intel Atom x5/z7 mini PC or sticks with a 32-bit UEFI bootloader. If you have such device, you can try it the following instructions using a USB flash drive: Download and install Rufus or LibreELEC SD USB creator Download and unpack LibreELEC 8 32-bit UEFI image file Launch your USB creator program, select the firmware file, and make a bootable USB flash […]

Android 7.0, Android TV 7.0, and Yocto Project Ported to Pine A64 Boards

A few weeks ago, Raspberry Pi 3 got an Android 7.0 Nougat port, and it’s usable for some app even simple games like Angry Bird, but there are still problems with 3D graphics, and hardware video decoding. But thanks to Pine64 forum’s member Ayufan, we now have Android 7.0 and Android TV 7.0 for Pine A64 boards with 1GB or more memory with 3D graphics, and hardware video acceleration for most apps. Everything is said to pretty much work, but there are some known issues, such as camera support (being worked on now), touchscreen support (not tested), YouTube is limited to 360p/480p as it does not support hardware video decoding, and Widevine DRM is not supported. Android 7.0 has also been shown to be about 10 to 15% faster than Android 5.1.1 in GeekBench. Ronnie Bailey has shot a video showing Pine A64 running Android TV 7.0 Nougat. If you […]

Nextcloud Box is a $80 Private Cloud Server with 1TB HDD for Development Boards

While there are plenty of cloud services provided by companies such as Dropbox or Google, you may want to manage you own private cloud server instead for performance and/or privacy reasons. One typical way to do this is to install Owncloud or Nextcloud (a fork of Owncloud), on a Linux computer or board such as Raspberry Pi 3. The former is usually a little expensive for just this task, the latter often results in cable mess, and in both case, some people may not be comfortable with setting it all up. Nextcloud, Western Digital, and Canonical seems to have addressed most of those issues with Nextcloud Box including a 1TB USB 3.0 WDLabs harddrive, Nextcloud case with space for the drive and small ARM or x86 Linux development boards, and a micro USB power supply. The kit also include a micro SD card pre-loaded with Snappy Ubuntu Core, Apache, MySQL […]

Receive Android SMS & Call Notifications in Ubuntu 16.04 with KDE Connect (or Not?)

I often miss calls, and I may be slow to answer SMS on my Android phone, but I’m often in front of my computer, so I decided to look for solutions to show SMS and call notifications on my computer running Ubuntu 16.04. I first found LinConnect, but it does not seem to be developed anymore, and after some more research I discovered that KDE Connect should do the job. The developer just released KDE Connect 1.0 a few weeks ago with add encryption, the ability to reply to SMS from your computer and more… One person posted instructions for Kubuntu 16.04. There’s just a problem it won’t work with Unity desktop, only KDE Plasma, due to a lack of support for Qt 5.6. You can still use the older version without encryption and other new features by “simply” running:

However the installation failed for me:

An “apt […]

Widora-NEO OpenWrt WiFi IoT & Audio Board is Based on Mediatek MT7688 SoC, WM8960 Audio DAC

A couple of weeks ago, I reviewed ReSpeaker board combining MediaTek MT7688 WiFi SoC with WM8960 audio DAC, running OpenWrt, and allowing you to perform tasks using text-to-speech and speech-to-text thanks to the built-in microphone (or optional microphone array), and a 3.5mm audio jack to connect speakers, as well as several I/O pins. It turns out there’s been board with similar features, minus the built-in microphone, available in China for a while. Meet Widora-NEO. Widora-NEO board specifications: SoC – Mediatek MT7688AN MIPS SoC @ 580 MHz with built-in WiFi System Memory – 128 MB RAM Storage – 16MB SPI flash, micro SD card Connectivity – 10/100M Ethernet, 802.11 b/g/n WiFi 1T1R up to 150 Mbps with PCB antenna, or IPEX connector Audio – 3.5mm jack for stereo headphone and mono microphone, WM8960G audio codec USB – 1x micro USB port for programming via CP2104 chip, 1x micro USB host (or […]
