无法获得 iPhone/iPad 的相机访问权限

Question

在中继会话中使用带有 H.264 视频编解码器的 web (JS) 版 opentok 2.14.8。我使用 opentok reactJS 加速器示例应用程序作为基础。

目前，允许访问 camera/audio 弹出窗口在 Android (Chrome)、PC/Mac (Chrome/Firefox/Safari) 上运行良好。请注意，我手动触发了一个按钮以访问相机并显示提要。

在 iPhone/iPad 上尝试访问相机时出现此错误。

如何在 iPhone/iPad 上强制显示 'access to camera' 弹出窗口？注意：我已经在相同的设备上测试了 https://safari.opentokrtc.com/，它们运行良好。

Answer 1

我的猜测是您将分辨率设置为较低的值，例如 320x240。存在 iOS 无法给出此解决方案的问题。 https://bugs.webkit.org/show_bug.cgi?id=176349

如果您将代码更新为使用 640x480 而不是 iOS，您应该没问题。
