getusermedia

I'm developing an application for iOS, Android and Windows with React Native in which I need to show a webpage through a WebView . That webpage accesses the camera of the device, so it uses MediaDevices.getUserMedia() Javascript function. It works without problems in desktop, even in the Chrome app on the smartphone . However, when I call the webpage via the React Native <WebView /> , I get a PermissionDenied error. The problem is that no request is shown to let me accept that permission. It justs denies the request without asking. Here is a sample of my WebView element: <WebView style={{flex:

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

The desktopCapturer api example shows how to write a screen capture stream to a <video> element. // In the renderer process. var desktopCapturer = require('electron').desktopCapturer; desktopCapturer.getSources({types: ['window', 'screen']}, function(error, sources) { if (error) throw error; for (var i = 0; i < sources.length; ++i) { if (sources[i].name == "Electron") { navigator.webkitGetUserMedia({ audio: false, video: { mandatory: { chromeMediaSource: 'desktop', chromeMediaSourceId: sources[i].id, minWidth: 1280, maxWidth: 1280, minHeight: 720, maxHeight: 720 } } }, gotStream,

This question already has an answer here: How can I add predefined length to audio recorded from MediaRecorder in Chrome? 3 answers I am writing a software that manipulates camera stream video in firefox. I am generating a Blob with video type recorded with MediaRecorder API . What i am doing to save the blob as video in local storage is using FileSaver library : FileSaver.saveAs(BlobVideo,"video.mp4"); It seems the video doesnt have any max duration, so i cannot navigate in timeline in my newly generated video in VLC, for example. Is there a way to set duration metadatas on a blob video?

This question already has answers here : converting .wav file to .ogg in javascript (4 answers) So I have this HTML5 project I'm working on, where I'm converting an iOS app to a web-based one. Accompanying part of the content creation of the app is an audio recording, which I'm trying to replicate in JavaScript without the use of plugins; so far, I've been able to record audio from getUserMedia(), and turn it into a WAV thanks to Recorder.js. Now, however, I'm a bit lost. I currently have two separate views, one for recording content and one for playing it back, but I don't know how to get the

I have channelled the stream returned by getUserMedia to <video> element in html page, video now can be seen in that element. The problem is that if I pause the video from the controls of video element, and then resume after x seconds, then the timer being shown in video element will jump to pauseTime + x seconds. I guess this is because the stream is not getting paused as we pause the playback in video element. If so can we pause the stream too. That is the very thing of Streams, you can't pause them... But what you can do however, is to buffer this stream, and play what you've bufferred. To
