问题 I'm trying to write ppapi plugin for Chrome which will use webcam (show preview and write file). I have installed NaCl sdk with pepper_35 . There available examples in /examples/api/ folder: media_stream_audio and media_stream_video . The audio example works fine - requests access to microphone and shows some kind of preview. The "media_stream_video" example must show web-camera video preview, but when I load example on the local web server (with make serve command), there appears red rect,

问题 I'm developing a Google Chrome packaged app right now. I'm going to use webview tag to embed webpages for this app that I'm working on. And I was reading this document below that describe webview tag. https://developer.chrome.com/apps/tags/webview But, I didn't quite understand what this is for. Could anyone please explain what partition attribute is for? Thanks! <webview id="foo" src="http://www.google.com/" style="width:640px; height:480px" partition="persist:googlepluswidgets"></webview>

问题 I am working on a Chrome Packaged App that sends notifications (which are now all hooked up). However, when the user is not in the app -- the app is in the background with other windows on top of it -- the notification pops up for a bit and disappears. I would like to change the taskbar icon to orange, the same that the Hangouts packaged app does, so that the user knows there is a notification to view at a later time. I looked all though the notifications documentation and could not find any

问题 I'm trying to adjust microphone volume in Chrome App. Is is possible to do it? I'm using webrtc. 回答1: It's possible to use WebAudio and a gain filter to adjust the volume to set the volume of an audio/video tag (on the receiving end) Here is some sample code for the first option var audioContext = new AudioContext(); var sourceStream = audioContext.createMediaStreamSource(yourStream); var gain = audioContext.createGain(); sourceStream.connect(gain); gain.value = 0.9; gain.connect(audioContext

问题 I have an application which outputs text files periodically with data in it. The text files are initiated from within the application and a datetime/context sensitive name -- though always output to the same folder. I would like to write a chrome application that can watch the folder these files are output to, read them, parse them, and then display them in a friendly manner. However, there does not seem to be any obvious way to get the contents of a folder in a chrome app. I've read

问题 I've created a chrome app that opens in kiosk mode, inside my chrome app i have a webview which is similar to an iframe except it works for chrome apps. On the website inside the webview there is a link that tries to open in a new tab, and fails.. At the moment it just does nothing when the button is clicked. Is there a way to make all links inside the webview not open in new tabs? Or is there any other work around that you can think of? I firebugged the link and this is what it says (i was

问题 I have searched tutorials like https://developer.chrome.com/apps/app_identity, but I cannot see how I can retrieve a user's email address logged in chrome. I can only get a token for the chrome.identity api https://developer.chrome.com/apps/identity so the example code for getting the token works chrome.identity.getAuthToken({'interactive': true}, function(token) { console.log('user token: ' + token); }); but from here how do I get the email. Note: this is for an app not an extension, thus

问题 I have a Chrome App with a webview that has a 'persistent partition', I need to have a button that will clear all the data saved in that webview's partition. I've tried the following solution based on the official google samples but I can't get it to work var clearDataType = { appcache:true, cookies: true, fileSystems: true, indexedDB: true, localStorage: true, webSQL: true, } function clearCache() { document.getElementById('webview-window').clearData( { since: 0 }, // Remove all browsing
