问题 I can get mediaDevices of 'videoinput' kind via navigator.mediaDevices.enumerateDevices() promise. I can get mediaStream via navigator.mediaDevices.getUserMedia(constraints) promise. What should constraints look like in order to have two video tracks in userMedia? 回答1: You can get max one video track and one audio track each time you call getUserMedia() , but you can call it multiple times. This may ask the user more than once though, depending on https, browser, and what the user does.

I am currently using an Android tablet and GetUserMedia to take pictures in my program. Apparently, the default camera used by GetUserMedia is the front camera. How do I use the rear camera as a default? Here's my code for GetUserMedia: navigator.getUserMedia({ "audio": false, "video": { mandatory: { minWidth: this.params.dest_width, minHeight: this.params.dest_height, //facingMode: "environment", }, } }, function(stream) { // got access, attach stream to video video.src = window.URL.createObjectURL( stream ) || stream; Webcam.stream = stream; Webcam.loaded = true; Webcam.live = true; Webcam

问题 I am capturing audio data using getUserMedia() and I want to send it to my server so I can save it as a Blob in a MySQL field. This is all I am trying to do. I have made several attempts to do this using WebRTC, but I don\'t even know at this point if this is right or even the best way to do this. Can anybody help me? Here is the code I am using to capture audio from the microphone: navigator.getUserMedia({ video:false, audio:true, },function(mediaStream){ // output mediaStream to speakers:

HTML5 getUserMedia record webcam, both audio and video

问题 Is it possible to use Chrome to capture video (webcam) and audio (microphone) from the browser and then save the stream as video file? I would like to use this to create a video/photobooth-like application that allows users to record a simple (30 second) message (both video and audio) to files that can later be watched. I have read the documentation but I have not (yet) seen any examples on how to capture both audio & video, also I did not find a way yet to store the results in a video file.
