GMSL2 camera kit supports 15-meter long cables, up to six cameras with NVIDIA Jetson Xavier AGX

6x gmsl2 cameras nvidia agx xavier devkit

We’ve recently seen it’s possible to use a long cable with the Raspberry Pi camera thanks to THine camera extension kit that works with 20-meter LAN cables using V-by-One HS technology. e-con Systems has now launched a similar solution for NVIDIA Jetson Xavier AGX, one of the most powerful Arm devkits available in 2021, with NileCAM21 Full HD GMSL2 HDR Camera that supports up to 15-meter long cable as well as LFM (LED Flickering Mitigation) technology. NileCAM21 camera features and specifications: Based on OnSemi AR0233 Full HD camera module with S-mount interchangeable lens holder Gigabit Multimedia Serial Link 2 (GMSL2) interface with FAKRA connector Shielded coaxial cable for transmission of power and data over long distances (up to 15m) High Dynamic Range (HDR) with LED Flickering Mitigation (LFM) Supported resolutions and max frame rates for uncompressed UYVY streaming VGA (640 x 480) up to 60 fps qHD (960 x 540) up to 58 fps HD (1280 x 720) up to […]

Open-source H.265/HEVC Hantro G2 decoder driver added to NXP i.MX 8M in Linux

H.265 Linux open-source driver NXP iMX 8M Quad

Getting open-source multimedia drivers on Arm Linux is one of the most difficult tasks, that’s why there’s no much talk about open-source GPU drivers for 2D & 3D graphics acceleration, but work on video hardware decoding and encoding is also a challenge. We’ve previously seen Bootlin work on Cedrus open-source driver for Allwinner VPU (Video Processing Unit), but Collabora has been working on open-source drivers for VeriSilicon’s Hantro G1 and G2 VPU found in some Rockchip, NXP, and Microchip processors. The company previously managed to have Hantro G1 open-source driver for JPEG, MPEG-2, VP8, and H.264 codecs, but H.265/HEVC relies on Hantro G2, and the patch for H.265 hardware video decoding on NXP i.MX 8M Quad has just been submitted to mainline Linux. Benjamin Gaignard explains more in his commit message: The IMX8MQ got two VPUs but until now only G1 has been enabled This series aim to add the second VPU (aka G2) and provide basic HEVC decoding support.

How to develop Gstreamer-based video conferencing apps for RDK & Linux set-top boxes

CNXSoft: This is a guest post by Promwad that explains the basic steps to develop a video conferencing app with Gstreamer on TV boxes running Linux. The COVID-19 pandemic has become a catalyst for new online services. For example, Zoom became so successful that it overtook IBM in terms of capitalization this month. The software engineers at Promwad were inspired by this success and decided to go even further: what about implementing video conferencing on Smart TV and STBs? Then the users of such an application will have an opportunity to communicate not only at work but also to enjoy remote meetings with friends, cheer for a soccer team, watch a movie together, or do sports with a coach. For some reason, most digital TV operators do not have such a service, although, from an engineering point of view, all these features can be implemented on set-top boxes based on Linux/Android and RDK. Let’s analyze the architecture of a Zoom-like […]

Getting Started with NVIDIA Jetson Nano Devkit: Inference using Images, RTSP Video Stream

Last month I received NVIDIA Jetson Nano developer kit together with 52Pi ICE Tower Cooling Fan, and the main goal was to compare the performance of the board with the stock heatsink or 52Pi heatsink + fan combo. But the stock heatsink does a very good job of cooling the board, and typical CPU stress tests do not make the processor throttle at all. So I had to stress the GPU as well, as it takes some efforts to set it up all, so I’ll report my experience configuring the board, and running AI test programs including running objects detection on an RTSP video stream. Setting up NVIDIA Jetson Nano Board Preparing the board is very much like you’d do with other SBC’s such as the Raspberry Pi, and NVIDIA has a nicely put getting started guide, so I won’t go into too many details here. To summarize: Download the latest firmware image (nv-jetson-nano-sd-card-image-r32.2.3.zip at the time of the review) […]

Embedded Linux Conference (ELC) Europe 2019 Schedule – October 28-30

Embedded Linux Conference Europe 2019 Schedule

I may have just written about Linaro Connect San Diego 2019 schedule, but there’s another interesting event that will also take place this fall: the Embedded Linux Conference Europe on October 28 -30, 2019 in Lyon, France. The full schedule was also published by the Linux Foundation a few days ago, so I’ll create a virtual schedule to see what interesting topics will be addressed during the 3-day event. Monday, October 28 11:30 – 12:05 – Debian and Yocto Project-Based Long-Term Maintenance Approaches for Embedded Products by Kazuhiro Hayashi, Toshiba & Jan Kiszka, Siemens AG In industrial products, 10+ years maintenance is required, including security fixes, reproducible builds, and continuous system updates. Selecting appropriate base systems and tools is necessary for efficient product development. Debian has been applied to industrial products because of its stability, long-term supports, and powerful tools for packages development. The CIP Project, which provides scalable and customizable base image and BSP layers, is now used in […]

FOSDEM 2018 Open Source Developers Meeting Schedule

FOSDEM (Free and Open Source Software Developers’ European Meeting) occurs every year on the first week-end of February, where developers meet for two days discussing about open source software projects. FOSDEM 2018 will take place on February 3-4 this year with 652 speakers, 684 events, and 57 tracks, an increase over last year 608 speakers, 653 events, and 54 tracks. There will be 8 main tracks namely: Community, History, Miscellaneous, Performance, Python, Security and Encryption, Space, and Global Diversity CFP Day. There will also be 33 developer rooms, and since the full schedule is now available, I’ll make a virtual schedule mostly based on sessions from the Embedded, mobile, and automotive, Hardware Enablement, and Internet of Things devrooms. Saturday 3, 2018 09:50 – 10:15 – Turning On the Lights with Home Assistant and MQTT by Leon Anavi In this presentation you will learn the exact steps for using MQTT JSON Light component of the open source home automation platform Home […]

Amlogic A111, A112 & A113 Processors are Designed for Audio Applications, Smart Speakers

Amlogic processors are mostly found in TVs and TV boxes, but the company is now apparently entering a new market with A111, A112, and A113 audio processors. I was first made aware of those new processors through Buildroot OpenLinux Release Notes V20170831.pdf document posted on their Open Linux website, where two boards with Amlogic A113D and A113X are shown. First, S400 board with the following key features/specifications: SoC – Amlogic A113D CPU System Memory – 1GB DDR3 Storage – 512MB SLC NAND flash Display I/F – MIPI interface Connectivity – Gigabit Ethernet SDIO WiFi/BT (AP6356S) Audio SPDIF_IN/SPDIF_OUT LINE_IN/LINE_OUT 2x Audio headers (MIC_Connector & SPK_Connector) USB – 1x USB 2.0 OTG Expansion – 2x PCIe ports Misc – 6x ADC Keys, IR_IN/IR_OUT, UART Interface (RS232) The second S420 board is based on A113X SoC, and comes with less features (no display, no Ethernet, no PCIe…), less memory: SoC – Amlogic A113X CPU System Memory – 512 MB DDR3 Storage – 512MB […]
