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

2017 update : Apple just announced that getUserMedia will finally be supported in iOS11 .
Aug 2019 update : ONLY works in Safari, not in a WebView of any kind. Thanks @Klathmon for the comment.
The quaggaJS page has a feature compatibility matrix which answers your question:
getusermedia is not supported on iOS safari.
As per the quaggaJS documentation ( https://github.com/serratus/quaggaJS#browser-support )
Quagga makes use of many modern Web-APIs which are not implemented by all browsers yet. There are two modes in which Quagga operates:
analyzing static images and
using a camera to decode the images from a live-stream. The latter requires the presence of the MediaDevices API. You can track the compatibility of the used Web-APIs for each mode:
I would suggest that you use static image mode on iOS as live stream mode is not supported.
