Video-Engineering

We’re explaining the end-to-end systems the Facebook app leverages to deliver relevant content to people. Learn about our video-unification efforts that have simplified our product experience and infrastructure, in-depth details around mobile delivery, and new features we are working on in our video-content delivery stack. The end-to-end delivery of highly relevant, personalized, timely, and responsive [...] Read More... The post Inside Facebook’s video delivery system appeared first on Engineering at Meta.

Meta’s family of apps serves trillions of image download requests every day. And if you’re into high-quality images, you’ve probably noticed that Instagram and Threads have added support for high dynamic range (HDR) photos. Now people on Threads and Instagram can upload and share images that are more true-to-life, with the full color and range [...] Read More...

Bandwidth estimation (BWE) and congestion control play an important role in delivering high-quality real-time communication (RTC) across Meta’s family of apps. We’ve adopted a machine learning (ML)-based approach that allows us to solve networking problems holistically across cross-layers such as BWE, network resiliency, and transport. We’re sharing our experiment results from this approach, some of [...] Read More... The post Optimizing RTC bandwidth estimation with machine learning appeared first on Engineering at Meta.

At Meta, we support real-time communication (RTC) for billions of people through our apps, including Messenger, Instagram, and WhatsApp. We’ve seen significant benefits by adopting the AV1 codec for RTC. Here’s how we are improving the RTC video quality for our apps with tools like the AV1 codec, the challenges we face, and how we [...] Read More...

Meta has made it possible for people to upload high dynamic range (HDR) videos from their phone’s camera roll to Reels on Facebook and Instagram. To show standard dynamic range (SDR) UI elements and overlays legibly on top of HDR video, we render them at a brightness level comparable to the video itself. We solved [...] Read More...
