Quest Casting 2.0 allows creators and developers to record or stream uncropped widescreen to PC via USB 3.0.
Quest头戴式设备可以将佩戴者所看到的内容无线投射到支持Google Cast的电视设备、智能手机和网络浏览器。目前，这些无线投射方法并未发生改变，但投射到PC的其他方法是。这种方法通常面向开发人员和创作者，是Meta Quest Developer Hub应用程序（适用于Windows和Mac）中的投射功能。
Meta Quest Developer Hub (formerly Oculus Developer Hub) allows developers to manage connected Quest headsets, including accessing files, installing, uninstalling, and launching APKs, taking screenshots and videos, running ADB commands, and analyzing performance.
The Meta Quest Developer Hub also has its own casting capabilities, with a beta Casting 2.0 option added this week.
Typically, when capturing or casting video on the Quest, creators have to choose between a panoramic 1:1 aspect ratio and a cropped 16:9 view, which typically places virtual hands and close objects on top of each other. Take it out of the picture. This is because most headsets have roughly the same horizontal and vertical field of view for each lens.
Casting 2.0's "Movie" mode solves this problem by telling the headset to expand the rendering field of view horizontally to capture the full 16:9 image without cropping the top or bottom.
Unlike the standard casting feature, Casting 2.0 only works over USB 3.0, not Wi-Fi or a regular USB 2.0 cable. This won't be too much of an issue for many Quest creators and developers, though, as many of them already have long USB 3.0 cables for Link PC VR functionality.
While testing Casting 2.0, I found that this wider rendering view seemed to come with some performance overhead, which is to be expected. In games using dynamic resolution, this only means the resolution is slightly reduced, while fixed-resolution applications may lose some frames.
Still, the uncropped widescreen should be more suitable for recording or streaming content on platforms like YouTube for viewing on laptops, PCs, and TVs (or on your phone held in landscape orientation). Casting 2.0 will likely be greatly appreciated by YouTubers, Twitch streamers, and developers.
