I am making an chrome extension through which I can get a screenshot of user's desktop. I am using chrome.desktopCapture API to get stream of selected window. I am creating video element dynamically. Once its source it set, I invoked the play() method. Then I created a canvas element and used it to draw an image of video. I am also able to get the dataURL using canvas.toDataURL() but when i open this url I see no image. And also this URL value remains same even during new capture. Manifest.json - { "name": "Desktop Capture Example", "description": "Show desktop media picker UI", "version": "1"

I have a simple little dongle I want to debug by sending/receiving basic USB messages. It enumerates as an HID device (like an additional mouse), but am worried that I won't have access to it. I forgot the hardware and can't test with it for a couple days. Is it a futile effort to continue building a chrome extension to test it? Chrome App, USB documentation: https://developer.chrome.com/apps/app_usb Getting-started example: https://github.com/GoogleChrome/chrome-app-samples/tree/master/usb/knob Google Chrome now proposes a USB HID API. Have a look at the API: https://developer.chrome.com/apps

I need to be able to send postMessage from a Chrome App through a webview to the homepage and back. I have established PostMessage from the Chrome App to the homepage, and the PostMessage is also catched by the homepage and a new one is send back, but this PostMessage reply is not caught by the Chrome App. I can see that it is possible on the Chrome-App API.: The guest will be able to send replies to the embedder by posting message to event.source on the message event it receives. So the problem is that i cannot get the Chrome App to catch the reply from the homepage, even though i am using

I have a chrome packaged app that also includes a PNaCl/NaCl C++ module, as well as some data files which the NaCl module needs to read in. However, I am not able to get it to read in the files. I set it up according to all the documentation and official examples that I could find, as well as the answer to: How to include a data file in a chrome app for a native client module to read The nacl_io demo that comes with the SDK is able to do this, but it is in C, not C++. I came up with a simple example, which I'll post below. When you press the button on the page, the NaCl module should load the

I'm trying to use Google maps inside of a Chrome App. Whenever I try to load the javascript I get the error: "Refused to load the script 'https://maps.googleapis.com/maps/api/js?key=Key&sensor=true' because it violates the following Content Security Policy directive: "default-src 'self' chrome-extension-resource:". Note that 'script-src' was not explicitly set, so 'default-src' is used as a fallback." I thought about trying to use a webview or a sandbox, but am having issues implementing either. The sandbox has an issue because I also am doing a http request to a service with no 'Access

I'd like to use the chrome.identity API in a chrome packaged app to allow the user to authenticate with github . From the app side, I'm happy with: chrome.identity.launchWebAuthFlow( {'url':'https://github.com/login/oauth/authorize?client_id=clientidgoeshere','interactive':true}, functionToTakeRedirectURL ); But I'm unsure what the redirect URL should be on the github side. When the app is live, I'll set the redirect url to https://appidgoeshere.chromiumapp.org on the github application page, but I don't think that url is available until the app is live. Does anybody know where to point the
