用于在iOS上读取实时摄像头流的getUserMedia（）的替代方案？ [英] Alternative to getUserMedia() for reading live camera stream on iOS?

问题描述

我们正在使用QuaggaJS构建移动条形码扫描仪，可直接从设备的相机流中读取条形码。在桌面/ Android上工作正常，但在iOS上根本不起作用。

We are building a mobile barcode-scanner using QuaggaJS that reads barcodes directly from the device's camera stream. Works fine on desktop/Android, but doesn't work at all on iOS.

从最初的研究中，我发现iOS根本不支持WebRTC / getUserMedia 通过Safari或iOS Chrome（下面的相关链接），这是QuaggaJS用来读取相机流的。

From initial research, I've found that iOS simply does not support WebRTC/getUserMedia through Safari or iOS Chrome (related links below), which is what QuaggaJS uses to read the camera stream.

I还见过关于在iOS上捕获静态图像的这个问题，但提供的答案仅为用于捕获静止图像，而不是用于实时读取流。

I've also seen this question about capturing a still image on iOS, but the answer provided is only for capturing a still image, not for reading the stream real-time.

我的问题 - 是否还有其他方法可以从中获取流iOS相机？也许QuaggaJS以外的替代库不使用 getUserMedia ？我不是很精通Javascript，所以我不确定是否有可能的方法来访问除 getUserMedia 之外的相机流。

My question - is there any other way to grab the stream from an iOS camera? Perhaps an alternate library other than QuaggaJS that does not use getUserMedia? I am not well-versed in Javascript, so I am not sure if there even is a possible way to access the camera stream other than getUserMedia.

这里的否是可接受的答案;我只是在寻找更有经验的人来提供指导。

A "no" is an acceptable answer here; I'm simply looking for someone more experienced to provide guidance.
