Polyfill file input with accept capture (using getUserMedia to capture?)

由 二次信任 提交于 2019-12-07 03:30:35
问题 I want to enable image (& audio & video) uploads in a survey framework. To do so, input file is nearly sufficient for my purposes. On some mobile browsers <input type="file" accept="image/*;capture=camera"> is a really simple way of letting users choose to upload an existing image or to take a new one. Of course the UI for viewing and choosing among the pictures is provided too. Desktop browsers did not go this route. Instead, some pretty nice stuff seems to be possible using getUserMedia() .

问题 Trying to call drawImage with a video whose source is a webcam feed seems to fail in Firefox with an NS_ERROR_NOT_AVAILABLE: Component is not available . I have tried to wait for every event the video tag fires: play , playing , canplay , loadeddata , loadedmetadata , and so on, and nothing works. This seems to be because these events are firing before the stream is properly loaded into the <video> element. JSFiddle with error (You can view the error in the console) A side effect is that the

问题 it is possible to access different microphones at the same time using getUserMedia() ? This whould be useful to filter out background noise; create some sort of stereoscopic effect; make available multiple audio tracks for an international streaming conference. Apparently, it is quite tricky for video source: Capture video from several webcams with getUserMedia I was wondering if, for the audio source, the problem was different. 回答1: You should be able to do this but I imagine the browser

getUserMedia alternative for iOS

由 懵懂的女人 提交于 2019-12-06 14:12:30
问题 Does anyone know if there are any (near) future plans to enable getUserMedia for Safari on iOS? Secondarily, does anyone know of any work-arounds to access the camera from a standard mobile website on an iPhone? I saw a post that referenced: <input type="file" accept="image/*" capture="camera"> Can anyone confirm that this really works, and would I use this in lieu of getUserMedia, or would I do a browser/device detect first to determine if I should go the getUserMedia v. capture="camera"

What's the state of the art for getting user media in browsers?

由 ⅰ亾dé卋堺 提交于 2019-12-06 10:25:55
From MDN's page on Navigator.getUserMedia() : Deprecated This feature has been removed from the Web standards. Though some browsers may still support it, it is in the process of being dropped. Do not use it in old or new projects. Pages or Web apps using it may break at any time. ... So how in heaven can we access user media in browsers? I see around some webapps that are perfectly capable to detect a smartphone camera so what is the solution? For example this doesn't work anymore http://www.html5rocks.com/en/tutorials/getusermedia/intro/ jib The state of the art at the moment is navigator
