Since the Chromecast dongle is using a lightweight version of chrome and able to display (cast;-) content from the cloud, would it not make sense that the fuller version of chrome (on windows, Android, and other platforms) would also be able to be a display device?
In other words, it would allow to cast from a smart phone to a tablet, laptop, or anything that runs Chrome. Simply have these devices added to the list of castable mediums...
Additionally, it looks like a simple and great way to make the technology also support multiple screen sharing...
I suspect you are confusing chrome the web browser (https://en.wikipedia.org/wiki/Google_Chrome) with chrome the operating system (http://en.wikipedia.org/wiki/Chrome_OS).
Chromecast as currently available is only good for accepting comands from compatible software (chrome the browser, the youtube app on android or ios etc) at which point it then streams the requested data from the internet, not from your phone/tablet/computer.
Your idea is not supported, which is stunning as Android has had built in support for screen mirroring via miracast since v4.2.
There's also no mention of direct content streaming, for instance via DLNA, an open protocol designed for EXACTLY THAT.
In fact, a better approach here would have been to make the chromecast dongle a DLNA device and then implement support for it on the google play music and youtube ends.
https://developers.google.com/cast/devprev - don't notice that ability off-hand... it mentions having to email mac addresses and websites and things to 'whitelist' for development, if you could just use your browser I wouldn't guess the dev proccess would be so convoluted.

I can not use an external camera connected via BlackMagic in WebRTC.
I tried it in my source code, web versions of Google Hangout, appear.in (whereby.com), etc in Chrome, Firefox, Safari. Anything worked.
Any idea how I can make it work at least for one browser?
You can't.
Unfortunately, most Blackmagic hardware has proprietary APIs and cannot be used as a standard device. This is by design. They only want to support software that fully utilizes the capabilities of their hardware.
The only product I know of that they make that isn't proprietary in nature is the "Web Presenter" which is standard UVC, allowing you to use standard OS-provided drivers and capabilities.
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.
I have a task to create a client application which can show notifications to a user with a high probability of notifications being noticed.
The application should work on Android (2.0+)/iOS/WP.
Here is the use case:
The user starts the Application and performs some Action. Then he switches to the home screen/another application.
The response to the Action makes the Application to issue a notification. The notification is noticed by the user disregarding of what another application (or home screen) he uses on his mobile device at the moment.
There is no requirement for the application to be a native app or to be a web browser-based mobile app. The notification could be a sound or a vibration on the device, but I know that accessing the vibrations from within a browser is still tricky.
Here are my research results of making universal sound/vibro notification mechanism so far:
it seems that making a mobile device vibrate from a browser works only in mobile Firefox (no iOS, no WP);
the support of the audio html5 tag is still experimental, it doesn't work on each and every browser/device;
the sound alert from this example works only in mobile Firefox (asks for a plugin to play an mp3 sound), the Android browser just remains silent.
So, the question is:
Is there any way to force a user of a mobile device (Android 2.0+/iOS/WP) to view a notification from a mobile application? Is the only way to do this is to write a native app for each mobile platform?
I would propose PhoneGap for that particular problem.
Among other things it features cross-platform alert, sound and vibrator notifications.
Only quirk for Windows Phone 7 is that the Cordova lib includes a generic beep file that is used. You should consult the Notification reference page to make sure if it can help you.
I have a HTML/Javascript web application which integrates with a device's camera using PhoneGap.
Is there any way we can run the application on a Windows 7 tablet (e.g. as a normal website) and be able to integrate with the camera on the device.
You will be, eventually, when the getUserMedia API is implemented in more browsers (currently only available in Opera and special builds of other browsers), but at the moment, no.
I don't believe there is a way to do this.
We enabled photos to be dragged into the application to support this feature. It means the user takes a photo as dictated by the tablet and then has to drag/select the appropriate photo file to add to the application.
Web browser plug-ins such as Flash already provide VoIP functionality in a web browser, but is it possible to have browser VoIP without any plug-ins?
Ericsson Labs has posted information using the device element to allow for microphone input. This, in addition with WebSockets could be used to implement VoIP. However, the device element is not implemented in any web browser yet.
No there isn't but the device element will likely be the way in the future, as you mentioned. I don't think it will take too long for browsers to look into it however. There are also the WAC APIs, but they are only on mobile, and not shipping quite yet.
Update: There is now a standard in development called WebRTC. Drafts of this spec are supported by Chrome and Firefox. Microsoft have made an alternative proposal called CU-RTC-Web
