JellyFin adds support for Rockchip RK3588 MPP hardware acceleration

Jellyfin open-source media server has recently added support for Rockchip RK3588 MPP hardware acceleration, which means the software supports video hardware decoding and encoding, hardware scalers, and other features. The GitHub request lists the following changes: Add full HWA transcoding pipeline for Rockchip RKMPP HW decoder (MPEG1, MPEG2, MPEG4, H264, HEVC, VP8, VP9, AV1) HW encoder (H264, HEVC) up to 1080p @ 480fps / 4k @ 120fps on RK3588 HW scaler, format conversion, and subtitle burn-in HW HDR-to-SDR tone-mapping (requires OpenCL, RK3588 only) The OpenCL runtime can be downloaded and installed from libmali-valhall-g610-g13p0-x11-wayland-gbm_1.9-1_arm64.deb Support lossless AFBC (Arm frame buffer compression) to save memory bandwidth and improve FPS Support async RGA filter and MPP encoder If indeed decoding and encoding can be performed simultaneously, that would mean video transcoding can be offloaded to the Rockchip RK3588’s VPU. The changes has been tested with Linux 5.10 and Linux 6.1, but do not […]

Femto Mega 3D depth camera review – OrbbecViewer and Orbbec SDK in Ubuntu 22.04, body tracking in Windows 11

We had a quick look at the Orbbec Femto Mega 3D depth and 4K RGB camera at the end of last year with a look at the hardware and a quick try with the OrbbecViewer program in Ubuntu 22.04. I’ve now had the time to test the OrbbecViewer in more detail, check out the Orbbec SDK in Linux and various samples, and finally test the Femto Mega with a body tracking application using Unity in Windows 11. A closer look at OrbbecViewer program and settings As noted in the first part of the review, the OrbbecViewer program provides color, depth, and IR views for the camera. Let’s go into details for each. The Color mode would be the same as your standard USB color camera. The Femto Mega supports resolution from 1280×720 at 30 fps to 3840×2160 at 25 fps using MJPG, H.264, H.265, or RGB (converted from MJPG). We […]

Banana Pi BPI-M7 – A thin Rockchip RK3588 SBC with dual 2.5GbE, M.2 NVMe storage, HDMI 2.1, and more

Banana Pi BPI-M7 SBC is powered by a Rockchip RK3588 SoC and comes with a low profile design that reminds me of boards from Khadas such as the Khadas Edge2 or VIM4 SBCs but with a few extra ports thanks to the larger form factor. The Banana Pi BPI-M7 single board computer is equipped with up to 32GB RAM and 128GB eMMC flash and features an M.2 2280 socket for one NVMe SSD, three display interfaces (HDMI, USB-C, MIPI DSI), two camera connectors, dual 2.5GbE, WiFi 6 and Bluetooth 5.2, a few USB ports, and a 40-pin GPIO header for expansion. Banana Pi BPI-M7 specifications: SoC – Rockchip RK3588 octa-core processor with CPU – 4x Cortex‑A76 cores @ up to 2.4 GHz, 4x Cortex‑A55 core @ 1.8 GHz GPU – Arm Mali-G610 MP4 “Odin” GPU Video decoder – 8Kp60 H.265, VP9, AVS2, 8Kp30 H.264 AVC/MVC, 4Kp60 AV1, 1080p60 MPEG-2/-1, VC-1, […]

Lichee Console 4A RISC-V devkit testing – Part 2: benchmarks and features in Debian 12

Sipeed Lichee Console 4A RISC-V devkit review

When checking out the hardware of the Lichee Console 4A portable RISC-V development terminal in the first part of the review, I noted that I had some troubles with the display that did not work properly. I did a little massage to “fix” the display, but unsurprisingly it ended up not being a long-term solution. So I had to open a case a few times and ended up breaking the wires to the fan… Each time I reassembled the device, the display only worked for a few seconds or minutes if at all. So I decided to test the system by keeping it open, as the display is working reliably that way. So I won’t be able to do a proper review testing the device on the go, but I still tested all features and benchmarked the T-Head TH1520 mini laptop with Debian 12, and will report my findings in […]

Vivante NPU (found in Amlogic A311D) gets its open-source driver upstreamed to Mesa

The Teflon project is an open-source TensorFlow Lite delegate that currently supports VeriSilicon Vivante NPU and aims to support several other AI accelerators over time. The project has recently been upstreamed to Mesa meaning AI inference with open-source software will work out of the box in supported hardware once Mesa 24.1 is released in May 2024. Teflon relies on the Etnaviv open-source driver better known for working with Vivante GPUs found, for instance, in NXP i.MX processors, but Tomeu Vizoso also worked on implementing Vivante NPU support since May 2022 thanks to a sponsorship from Libre Computer and documented the development progress on this blog. The VeriSilicon Vivante “VIPNano-QI.7120” 5 TOPS NPU is found in the Amlogic A311D processor, and Tomeu tested Teflon with the Etnaviv NPU drive on both the Libre Computer AML-A311D-CC Alta and Khadas VIM3 single board computers with decent performance although still slower than with the […]

GEEKOM Mini IT12 Review – Part 3: Ubuntu 22.04 Linux on an Intel Core i7-12650H mini computer

GEEKOM Mini IT12 mini PC Review Ubuntu 22.04 Linux

We first checked out the hardware of GEEKOM Mini IT12 with an unboxing and teardown, before testing the Intel Core i7-12650H mini PC with Windows 11 Pro in the second part of the review, and we’ve now had time to test the device with Ubuntu 22.04 to see how well (or not) it works with a Linux distribution. In the third part of the review, we will report our experience with installing Ubuntu 22.04 on the GEEKOM Mini IT12, checking all main features, and benchmarking the system to evaluate its performance. This includes some networking and storage performance tests, a stress test to check CPU temperature and cooling performance, and the measurement of the fan noise and power consumption. Ubuntu 22.04 installation on GEEKOM Mini IT12 Since we wanted to install Ubuntu 22.04 alongside Windows 11 Pro, we shrunk the Windows 11 partition by about half in the Disk Management […]

FOSDEM 2024 schedule – Open-source embedded, mobile, IoT, robotics, RISC-V, etc..

FOSDEM – which stands for Free and Open Source Software Developers’ European Meeting – is a free-to-participate event where thousands of developers meet in Brussels on the first week-end of February to discuss open-source software & hardware projects. FOSDEM 2024 will take place on February 3-4 with 880 speakers, 818 events, and 66 tracks. Although I won’t attend, I’ve created a virtual schedule like every year with sessions most relevant to the topics covered on CNX Software from the “Embedded, Mobile and Automotive” and “Open Hardware and CAD/CAM” devrooms, but also other devrooms including “FOSS Mobile Devices”, “ Energy: Reimagining this Ecosystem through Open Source”, “RISC-V”, and others. FOSDEM Day 1 – Saturday, February 3, 2024 10:30 – 10:55 – Screen Sharing on Raspberry Pi 5 Using VNC in Weston and Wayland with the Yocto Project and OpenEmbedded by Leon Anavi In 2023, embedded Linux developers received eagerly awaited news: […]
