Hardware-Accelerated FFmpeg on NVIDIA Jetson AGX Orin

This technical guide explains how to compile FFmpeg with hardware acceleration (NVENC/NVDEC) for the NVIDIA Jetson AGX Orin 64GB running Ubuntu 22.04 LTS and JetPack 6.2.2 (CUDA 12.6). It walks through installing system dependencies and the NVIDIA codec headers, cloning and configuring FFmpeg with explicit CUDA/NVENC/NVDEC flags, compiling (recommended make -j12 on the 12-core AGX Orin), and verifying available NV encoders/decoders. The article compares use cases and performance trade-offs across FFmpeg (custom build), NVIDIA DeepStream (for real-time AI inference with zero-copy/TensorRT), GStreamer (L4T plugins), and CUDA‑compiled OpenCV, and gives architectural recommendations on when to use each tool for edge video, streaming, and AI inference scenarios.

WP Multitool Adds Plugin Performance Score

WP Multitool 1.1.19 introduces a new Plugin Performance Score module that adds a Performance column to the WordPress Plugins admin page. For each installed plugin the column shows a deterministic score (0–100), PHP memory usage, and number of database queries based on benchmark data from makewpfast.com. Benchmarks are run in isolated Docker containers on clean WordPress installs (one plugin active at a time). The plugin ships with a static ~220 KB bundled benchmark data file (cached by PHP opcache) and covers about 5,000 plugins; if a plugin is not in the dataset a dash is shown. The feature is enabled by default and the WP Multitool package includes 14 modules.

Chrome 144 Boosts WebGPU with Major Updates and Optimizations

Chrome 144 introduces multiple WebGPU updates: two WGSL language extensions (subgroup_id and uniform_buffer_standard_layout), a careful rollout of WebGPU on Linux starting with Intel Gen12+ GPUs (using Vulkan while Chromium remains on OpenGL), and performance optimizations that make writeBuffer() and writeTexture() up to 2x faster in some cases. The release notes also highlight Dawn-related updates, including an Android alpha of Kotlin bindings (androidx.webgpu) delivered via Jetpack. The WGSL extensions include guidance for feature detection (navigator.gpu.wgslLanguageFeatures) and recommends using requires-directives in shader code. The blog post notes subgroup_id is emulated on the D3D backend and documents further Dawn commit details.
