Alternative to getUserMedia() for reading live camera stream on iOS?
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:
- Static Images
- Live Stream
I would suggest that you use static image mode on iOS as live stream mode is not supported.
