2024 WebRTC in Open Source Review: A Quantitative Analysis

I have been updating a WebRTC in Open Source dataset derived from GitHub event data for 10 years now. I periodically update this to look for recent trends on WebRTC activity, popular repos, and new API usage. I hosted a live stream of my 2024 review back in December where Tsahi Levent-Levi joined to help […]

All the ways to send a video file over WebRTC

I am working on a personal Chrome Extension project where I need a way to convert a video file – like your standard mp4 – into a media stream, all within the browser. Adding a file as a src to a Video Element is easy enough. How hard could it be to convert a video […]

WebCodecs, WebTransport, and the Future of WebRTC

Explore the future of Real-Time Communications with WebrtcHacks as we delve into the use of WebCodecs and WebTransport as alternatives to WebRTC’s RTCPeerConnection. This comprehensive blog post features interviews with industry experts, a review of potential WebCodecs+WebTransport architecture, and a discussion on real-time media processing challenges. We also examine performance measurements, hardware encoder issues, and the practicality of these new technologies.

Web 上的视频帧处理 – WebAssembly、WebGPU、WebGL、WebCodecs、WebNN 和 WebTransport

Note: Chinese translation thanks to Xueyuan Jia and Xiaoqian Wu of the W3C. See the English version here.  W3C Web 技术标准专家 François Daoust 和 Dominique Hazaël-Massieux(Dom)先前与我们探讨了如何使用 WebCodecs 和 Streams 进行实时视频处理。那篇文章重点介绍了如何设置流水线以应付来自摄像头、WebRTC 流或其他来源的视频帧低延迟处理。演示了一些处理示例 — 改变颜色、覆盖图像,甚至是改变视频编解码。引用的其他用例还包括机器学习处理,例如添加虚拟背景。 今天,他们将重点讨论可用于进行实际视频处理的诸多技术选项。有很多技术用来读取和更改视频帧内的像素。他们全面回顾了当前基于 Web 的所有技术选项 — JavaScript、WebAssembly (wasm)、WebGPU、WebGL、WebCodecs、Web 神经网络(WebNN)和 WebTransport。其中一些技术已经存在一段时间,许多则是新出现的。 这是一篇关于与视频分析与操作的文章。感谢 François 和 Dominique 与我们分享他们的研究,测试 Web 上可用的进行视频处理的完整技术目录。 正文内容 视频帧处理选项 使用 JavaScript 像素格式 性能 其他考虑 使用 WebAssembly 演示代码 […]

Video Frame Processing on the Web – WebAssembly, WebGPU, WebGL, WebCodecs, WebNN, and WebTransport

There are a lot of options for reading and changing the pixels inside a video frame. In this post, W3C specialists François Daoust and Dominique Hazaël-Massieux (Dom) review every web-based option for processing video frames on the web available today – JavaScript, WebAssembly (wasm), WebGPU, WebGL, WebCodecs, Web Neural Networks (WebNN), and WebTransport.
