Facebook全面开放全景视频直播：Facebook现在已经在所有个人资料和页面上启用了Live 360直播功能，任何拥有360摄像头的用户都可以进行直播。全球发布时还大幅度提高了对不同相机的兼容性，并添加了空间音频功能。



Facebook Live是于2015年推出的视频直播服务，而360度视频直播服务是大势所趋。Facebook是世界上最大的社交网络，每月活跃用户高达18.7亿，并且一直对自己的直播服务有着较高的期待，好喝Twitter及YouTube进行竞争。


小扎一直是360视频格式的铁粉， 去年360度视频直播在一些指定页面上跟用户见了面，现在已经扩展到所有的页面都可以在几秒钟内开始直播，只要有兼容的相机。目前兼容的相机包括市场上主要的几个产品：最新的三星 Gear 360（2017）、Giroptic IO、Insta360 Nano / Air和ALLie Camera以及专业级Z CAM S1和诺基亚Ozo。


但是360视频直播功能还没提到VR， 许多当前支持的相机不能捕捉立体3D。此外，360视频的1920×960目标分辨率、30fps帧速率和4 Mbps目标比特率等指标远不是VR的理想规格。然而，引入空间音频支持是朝着这个方向迈出的重要一步。 360度音频能大大增强沉浸感，尤其是在戴着VR头显的时候。正如Facebook媒体博客文章中所说的那样，支持Live 360里的空间音频的相机也即将推出，会通过环绕声麦克风进行手动添加。
