h265web.js

h265web.js is a WebAssembly-powered video decoding library designed to enable playback and processing of H.265/HEVC video streams directly in web browsers without relying on native browser codec support. It provides a low-level decoding API that allows developers to build custom video players capable of handling raw H.265 streams, which are typically not widely supported natively in browsers. The project includes components for parsing H.265 bitstreams into NAL units and decoding them into raw YUV frames that can then be rendered onto a canvas or processed further. Its architecture separates parsing, decoding, and rendering, giving developers fine-grained control over how video data is handled and displayed. The system is designed to work with streaming data, allowing incremental feeding of video chunks and real-time decoding, which is useful for surveillance, streaming platforms, and custom media pipelines.
