VVenC & VVdeC H.266 open source video encoder and decoder work on x86 and Arm

H.266 video decoder windowslinux macOS android

VVenC and VVdeC are open-source software H.266/VCC video encoder and decoder respectively that are optimized to use SIMD instructions on x86 (SSE42/SIMDe and AVX2) and Arm, and the decoder runs on Windows, Linux, macOS, and Android. H.266, aka VCC (Versatile Video Coding) video compression standard was adopted in 2020 promising to reduce data requirements by around 50% compared to the previous H.265/HEVC standard at the same visual quality. H.266 should also outperform the royalty-free AV1 video codec. We hadn’t seen news since the announcement, but this may be changing with the Realtek RTD1319D processor unveiled with support for both 4K H.266 and AV1 video decoding last September, and progress made on the VVenC & VVdeC H.266 open-source software encoder/decoder as been discussed during FOSDEM 2023. The Fraunhofer HHI group has been working on VVdeC and VVenC since the specifications were finalized in 2022. Both are based on VTM reference software […]

Hands-on experience with StarFive VisionFive 2 RISC-V SBC using Debian 12

StarFive sent me one of their VisionFive 2 RISC-V SBC for evaluation and review. I got the model with dual Gigabit Ethernet and 8GB RAM, and I’ll report my experience with the Debian 12 “bookworm” image. But note that won’t exactly be a review since the board is unreviewable at this time. It’s really for early adopters and there are many issues to solve, and in this post, I’ll report what works and what doesn’t, and some of the challenges I encountered just to install the OS… VisionFive 2 unboxing The board comes in a package that reads “Embrace change, embrace the future”. The bottom side has some useful links and QR codes, and what you’ll want is the GitHub repository with the source code and instructions to build the image from source (Note: Ubuntu 16.04, 18.04, or 20.04 x86_64 recommended), as well as the RVspace forum section for the […]

Raspberry Pi Pico W gets Bluetooth support in SDK 1.5.0

The Raspberry Pi Pico W board was launched with a WiFi 4 and Bluetooth 5.2 module based on the Infineon CYW43439 wireless chip in June 2022, and I wrote a tutorial showing how to connect to WiFi a few days after the launch, but nothing about Bluetooth. That’s because while the Raspberry Pi Pico W hardware supports Bluetooth, we were told that Bluetooth was not enabled at the time, but might be at a later stage. Alasdair Allan, who is responsible for the Raspberry Pi documentation, said Bluetooth support was scheduled very soon, and the SDK 1.5.0 release of the Pico C SDK is now available with Bluetooth implemented using BTstack low footprint dual-mode Bluetooth stack. Bluetooth support is still considered Beta and the SDK 1.5.0 implements the following key features and updates: New libraries for Bluetooth Low Energy (LE) support. Bluetooth Classic support. Bluetooth Sub Band Coding (SBC) encoder […]

9Tripod Pico Pi V2.0 SBC features Rockchip RK3588S SoC in Raspberry Pi 4 form factor

9Tripod Pico Pi V2.0 is the third Rockchip RK3588S SBC offering a powerful alternative to Raspberry Pi 4 while keeping the same form factor. It follows the Cool Pi 4 and Radxa ROCK5 Model A single board computers introduced in the last couple of months. The Pico Pi SBC, not to be confused with the Raspberry Pi Pico :), comes with 1GB to 32GB RAM, 4GB to 128GB eMMC flash, and pretty much the same port layout as the Raspberry Pi 4, except for one of the micro HDMI ports being replaced by a USB Type-C port with support for DisplayPort. 9Tripod Pico Pi V2.0 specifications: SoC – Rockchip RK3588S CPU – Octa-core processor with 4x Cortex-A76 cores @ up to 2.2-2.4 GHz, 4x Cortex-A55 cores @ up to 1.8 GHz GPU – Arm Mali-G610 GPU with OpenGL ES 3.2, OpenCL 2.2, and Vulkan 1.2 support VPU – 8Kp60 video […]

Balthazar – An open-source hardware modular RISC-V, Arm, or FPGA laptop

The Balthazar Personal Computing Device (BPCD) is an open-source hardware 13.3-inch laptop with a RISC-V, Arm, or FPGA module and designed to be upgradable, expandable, and sustainable. The developers say the laptop is based on a few concepts inspired by the EOMA68 project. The EOMA68 is a CPU module based on the PCMCIA form factor, and an Allwinner A20 EOMA68 module was showcased in a prototype of the Rhombus Tech 15.6-inch Libre Laptop but I don’t think the project was ever manufactured. Balthazar laptop features: SoM with RISC-V, FPGA, or Arm Cortex-A7x processor plus memory and flash Storage – SATA SSD, eSATA connector, microSD card socket Display – 13.3-inch non-glare display Video Output – HDMI Audio – Speakers, detachable microphone array Camera – Detachable webcam Connectivity – Ethernet, WiFi USB – 2x USB 3.0 ports, Micro USB OTG port, Micro USB port User input Waterproof keyboard with an illuminated track-point […]

Meet Puya PY32 – The 8-cent Arm Cortex-M0+ microcontroller

Puya Semiconductor (Shanghai) PY32 Arm Cortex-M0+ microcontroller family may be the world’s cheapest 32-bit Arm MCUs with one of the parts – PY32F002AL15S6TU – selling for under 8 cents per unit in 5K+ orders with 3KB SRAM, 20KB flash in an 8-pin SOP-8 package. Back in 2016, when I searched for the world’s cheapest MCU, I found Holtek HT48R002 8-bit microcontroller, and a few years later (2019), Padauk PMS150C “3 Cents” MCU came to my attention. However, both are 8-bit microcontrollers that come with OTG (One-Time Programming) ROM, meaning they can’t be easily used for development or updated. The Puya PY32 microcontrollers are in the same price range but offer a 32-bit Arm Cortex-M0+ core clocked at 24 to 48MHz, 16KB to 64KB flash storage, and 2KB to 8KB SRAM. There are three PY32 sub-families, but let’s check out the PY32F002 family in detail since those are the cheapest parts. […]

Bluetooth 5.4 adds electronic shelf label (ESL) support

The Bluetooth Special Interest Group (SIG) has just adopted the Bluetooth 5.4 Core Specification with features such as PAwR and EAD designed for Electronic Shelf Label (ESL) systems. The Bluetooth 5.3 Core Specification was adopted in August 2021 with various improvements, and Bluetooth 5.4 now follows with features that appear to be mainly interesting for large-scale Bluetooth networks with support for bi-directional communication with thousands of end nodes from a single access point, as would be the case for Electronic Shelf Label or Shelf Sensor systems. Four new features have been added to Bluetooth 5.4: Periodic Advertising with Responses (PAwR) – PAwR is a new Bluetooth Low Energy (LE) logical transport that provides a way to perform energy-efficient, bi-directional, communication in a large-scale one-to-many topology with up to up to 32,640 devices. Devices can also be allocated to groups allowing them to listen only to their group’s transmissions. An Electronic […]
