I am developing a chrome extension, and my point here is to record a browser tab , like Screencastify chrome extension records the browser tab. I referred desktopCapture , a chrome API which works perfectly for "screen" and "window" as DesktopCaptureSourceType, whereas for "tab" as DesktopCaptureSourceType, it throws an error as
desktopCapture.chooseDesktopMedia: Tab capture is not supported yet.
I have configured the required permissions in manifest.json of my extension. Could anyone suggest me a solution?
P.S : I need to record the chrome browser tab only, am not asking for a screen or window recording
This is a known issue: https://crbug.com/488262
However, you can use the chrome.tabCapture api instead. The downside is that you will have to split your interface between capturing tabs and screens/windows, as chrome.tabCapture doesn't provide an equivalent picker.
Why does Google have two separate screen capture apis? Good question.
The stream object generated by the chrome.tabCapture cant be shared outside the plugin code.
You will have to write the code to share the stream to server within the chrome plugin.
I'm building a simple web application that I want to be able to display on a TV screen using the Google Cast SDK, the Chrome browser and a Chromecast. I know with the Chromecast extension for Chrome Browser, I can cast a tab to a Chromecast device, which, from my laptop works perfectly. However, I want this exact same functionality, but available from iOS devices (iPads and iPhones) running the Chrome Browser.
It seems since Chrome v36 the Cast ability is baked into the iOS versions of Chrome. I have pulled in the Google Cast SDK per these instructions: https://developers.google.com/cast/docs/chrome_sender. I am able to get my iPad to connect to the Chromecast, but when I try to pass in a URL to a web page...
var mediaInfo = new chrome.cast.media.MediaInfo('http://google.com');
var request = new chrome.cast.media.LoadRequest(mediaInfo);
session.loadMedia(request, onMediaDiscovered.bind(this, 'loadMedia'), onMediaError);
I get an error...

I have found other, somewhat dated examples, saying I can build a custom Cast Receiver that holds an iFrame and renders the page in there, but I do not want to build a custom Cast Receiver.
Can I accomplish this with just a Cast Sender?
You always need a receiver on the chromecast; that is what gets loaded there. In general, you can either use a default/styled receiver or a custom one. The Default or Styled receivers can only handle media so you are left with the Custom option and having an iframe is the way to go.
Chrome on iOS doesn't support casting. There's a post from early 2016 saying this on the google product forums. (But my reputation is too low to post more than two links).
If it DID work, then all you would need to do is go to this site and choose the ChromeCast option and press Launch after typing in your website. This does work on Chrome on desktop.
The source for this sender/receiver is here: https://github.com/boombatower/chromecast-dashboard
I've used the boombatower.github.io receiver with my own code as sender in an iOS app. I'm also looking at whether an app extension would work, but I suspect not because of app extension limitations.
The goal is to start casting a content (video or other), from chrome mobile. Just like it is possible on standard Chrome for youtube or netflix videos, through the dedicated extension. I'm not talking about displaying the content of the mobile tab on the TV but just launching a cloud or LAN video on the big screen.
I know extensions are not available on chrome mobile (yet) but I was just wondering if there were any plans on making that possible in Chrome Mobile (with or without extensions).
It would be cool to be able to write a webapp that could launch videos on the big screen. The same webapp could be used on a smartphone, on a tablet or a on desktop computer.
Update:
I was thinking it could be easy to write a simple standalone js library for Google Cast device discovery. This could also be used to control the playback of cloud/LAN files within a webapp.
By looking at the chrome extension code, it looks like the discovery of Google Cast devices is done through the chrome.dial.* API. This API is not public yet. The extension asks for the following permissions:
"permissions": [
"tabs",
"tabCapture",
"dial",
"storage",
"networkingPrivate",
"https://*/*",
"http://*/*"
],
At this point, there is probably no hope of writing a standalone js library that would do the device discovery through chrome.dial.* as its access is restricted to extensions having asked for the specific permission.
Conclusion: To leverage the chrome.dial.* API, an extension is needed. And there are no public plans for extensions in Chrome Mobile.

It is a little unclear what you're asking, but it seems like you're asking if there is any hope of getting a native extension on the mobile version of Chrome.

Does Chrome for Android support apps and extensions?Chrome apps and extensions are currently not supported on Chrome for Android. We have no plans to announce at this time.
I wouldn't plan on having extensions anytime soon. You could always write a native application to the operating system and broadcast from there.
This is a question about debugging a project, not about writing the code.
I am on the final stages of developing an HTML5 web app. Fairly last minute, our client tells us it should run on IE8. Since I use the HTML5-canvas in the app, this required the addition of Google Chrome Frame. Once installed and testing, however, IE8's developer console no longer prints any data, and the HTML viewer never loads. Is this a bug? Is there a way to fix it? It will really suck if I need to debug with alerts...
From Google Chrome Frame documentation:
You can use the Web Inspector in GCF just as you would in the Google Chrome browser. To use it, right-click and choose "Inspect Element". Logging is available via the console.log method, and you can set breakpoints and inspect network activity.
Can I create a plugin or an extension for Google Chrome MOBILE (Android Google Chrome)?
If not, can I create an extension for Google Chrome (desktop), which will add a button in Google Chrome bar. This button will open the page in another web browser (in my own web browser), so, this button should launch my own web browser.
Extensions are not supported, see: https://developers.google.com/chrome/mobile/docs/faq .
Specifically:
Does Chrome for Android now support the embedded WebView for a hybrid native/web app?
A Chrome-based WebView is included in Android 4.4 (KitKat) and later. See the WebView overview for details.
Does Chrome for Android support apps and extensions?
Chrome apps and extensions are currently not supported on Chrome for
Android. We have no plans to announce at this time.
Can I write and deploy web apps on Chrome for Android?
Though Chrome apps are not currently supported, we would love to see great interactive web sites accessible by URL.
You can use bookmarklets (javascript code in a bookmark) - this also means they sync across devices.
I have loads - I prefix the name with zzz, so they are eazy to type in to the address bar and show in drop down predictions.
To get them to operate on a page you need to go to the page and then in the address bar type the bookmarklet name - this will cause the bookmarklet to execute in the context of the page.
edit
Just to highlight - for this to work, the bookmarklet name must be typed into the address bar while the page you want to operate in is being displayed - if you go off to select the bookmarklet in some other way the page context gets lost, and the bookmarklet operates on a new empty page.
I use
zzzpocket - send to pocket.
zzztwitter tweet this page
zzzmail email this page
zzzpressthis send this page to wordpress
zzztrello send this page to trello
and more...
and it works in chrome whatever platform I am currently logged on to.
Some extensions like blocksite use the accessibility service API to deploy extension like features to Chrome on Android. Might be worth a look through the play store. Otherwise, Firefox is your best bet, though many extensions don't work on mobile for some reason.

Just use a different browser.
Follow the steps given below to install Chrome extensions on your Android device.
Step 1: Open Google Play Store and download Yandex Browser. Install the browser on your phone.
Step 2: In the URL box of your new browser, open 'chrome.google.com/webstore’ by entering the same in the URL address.
Step 3: Look for the Chrome extension that you want and once you have it, tap on 'Add to Chrome.’
The added Chrome extension will now be automatically added to the Yandex browser.
I imagine that there are not many browsers supporting extension. Indeed, I have been interested in this question for the last year and I only found Dolphin supporting add-ons and other cool features announced few days ago. I want to test it soon.
