Question

在中继会话中使用带有H.264视频编解码器的opentok 2.14.8的Web（JS）版本。我以opentok reactJS加速器示例应用程序为基础。

当前，允许访问摄像头/音频弹出窗口在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摄像机并显示供稿。

当尝试在iPhone / iPad上访问相机时，出现此错误。

如何在iPhone / iPad上强制“访问相机”弹出窗口？注意：我已经在相同的设备上测试过https://safari.opentokrtc.com/，它们工作良好。

Answer 1

我的猜测是，您正在将分辨率设置为320x240之类的较低值。 iOS无法解决此问题。 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，则应该没问题。

无法获取iPhone / iPad的相机访问权限
