Can we implement or tie in miracast functionality into chrome cast? Or configure the receiver to accept miracast content?
Update: Miracast is actually supported now. See here.
=====
Miracast probably never will be supported on the ChromeCast (without some sort of hack). However, a little workaround does exist. If you're just wanting to stream video, just drag/load the video into a Chrome tab and use the ChromeCast extension to steam that video content to your device. It should work with any files that Chrome itself supports (PDF, images, etc). Hope that helps.

Does anyone know, if any desktop browser has support of HTML Media Capture? Maybe beta versions, or with experimental flag, or dev build?
Or maybe there is a polyfill for this functionality using getUserMedia?
I need it for POC, so I'm interested in any easy solution/workaround.
HTML Media Capture API vs. getUserMedia() seems to point to a getUserMedia equivalent of HTML Media Capture for desktop browsers
Any plans on Chrome or anyone else supporting this? I'd rather not build something in Flash if we can avoid it. I wouldn't mind trying to add it to Chrome or something myself if need be :)
Ericcson labs is working in an API for this:
https://labs.ericsson.com/developer-community/blog/beyond-html5-audio-capture-web-browsers
http://www.w3.org/TR/html-media-capture/
However, it hasn't became true. At the moment, you have no choice but using a plug-in (e.g. Flash) for audio recording.
It's in Chrome Canary... Finally! http://code.google.com/p/chromium/issues/detail?id=112367
You can use Recorder.JS to record from any Web Audio API node including getUserMedia and microphone input.
I plan to build a Chrome Extension that allows users to navigate web pages via voice commands.
To do so, I plan to put my speech recognition program on a backend server that connects with clients via Chrome extension.
Is it possible? I know how to develop an extension, but would appreciate if you could show a way of receiving voice input.
You don't need to modify Chrome.
Until the HTML5 tag gets landed in Chrome, your only option right now is to use NPAPI and include the plugin into your Extension. For more information visit this page:
http://code.google.com/chrome/extensions/npapi.html
You would have to implement a JavaScript audio input API using C++ inside Chromium, being aware that you have to transfer data through the sandbox, then once exported you can use the new API in your extension.
A lot of groundwork has already been done on specifying the audio API, read the details over at W3C:
http://chromium.googlecode.com/svn/trunk/samples/audio/specification/specification.html
Which links to details of a special build of Chrome with some already built samples:

I was wondering if I can access the webcam via a browser plugin e.g. for Firefox, Safari, Internet Explorer etc?
Are there already similar plugins/add-ons?
Thanks
It's possible to access the webcam through Flash, for instance.
An example of this is Omegle, which uses Flash to access the webcam.
An alternative is doing it in Silverlight, as in this example.
Finally, there's Java, in which you could write an applet to access the webcam. This article should demonstrate this.
If you wish to do it yourself, you will have to write the plugins yourself.
This can be done using the NPAPI for most browsers, or by writing a BHO (Browser Helper Object) for Internet Explorer.
How to interact with the webcam there depends on which language you choose, as you have full access to system libraries.
Note that writing a custom browser plugin is both harder, and a larger hassle for users, as they have to install something new, as opposed to just using their existing browser plugins.
I just found this:
http://www.html5rocks.com/en/tutorials/getusermedia/intro/
One year and a half after this question was made. I haven't tested it, but maybe it'll help.
From the link (just a copy/paste showing how to record something using the camera as input source):
<input type="file" accept="video/*;capture=camcorder">
<input type="file" accept="audio/*;capture=microphone">
None of the major Webbrowser's (IE, FF, Chrome) provide any special support for Webcams. You will need to either use the native OS's API (whatever that may be), or embed Flash in Webbrowser control in your browser plug-in.
You can use Mediadevices.getUserMedia (https://developer.mozilla.org/en-US/docs/Web/API/MediaDevices/getUserMedia) to capture webcam stream on browser (chrome and firefox).
To play with webcam stream on safari, you would have to use a pollyfill - https://github.com/Temasys/AdapterJS
To record the video/audio stream, you can make use of Media recorder api https://developer.mozilla.org/en-US/docs/Web/API/MediaRecorder
(Note : recording stream is still a challenge in Safari as there is no support/pollyfill. However, it works perfectly on Chrome and Firefox latest versions).To make video recording work on Safari, it maybe worthwhile to explore https://github.com/ronghanghu/webcamjs (Note flash plugin needs to be installed and enabled)

What is the recommended (cross-browser) video format to use on websites so that users' browsers (or most of them) wouldn't require to download a plugin to view it?
There is no single video that will play in every browser. If you want it to work across the most browsers, you're going to have to encode your video more than once. Dive into HTML5 video has the gory details.
You nest your video references so that browsers try these in order, falling back if it's not supported:
Ogg Theora
MP4 H.264
A Flash container displaying #2
Number 1 gets you Firefox 3.5 and Chrome. Number 2 gets you Safari and the mobile phone WebKit browsers. Number 3 gets you IE, Firefox ≤3, and Opera.
There is no such format available yet. The best way to go is:
Flash (most of the users have flash plugin installed already, 99% according to http://www.adobe.com/products/player_census/flashplayer/)
OGG (This will be available in HTML5 as standard)
Yes HTML5 will solve some of the problems of not needing a plugin, but different browser vendors have chosen different codecs and file formats. It's complicated, but Dive Into HTML 5 has a great article.
None! but you can do it with HTML 5 which is not implimented by all browsers ...
if you really need a video on your page i would recommend flash or silverlight
In a couple of months HTML 5 will be supported by almost all browsers on this planet. If you are planning to run your services in 2010 just use OGG open standard container format. It is unrestricted by software patents and is designed to provide for efficient streaming and manipulation of high quality digital multimedia. It is already supported by Firefox 3.5 and soon all browsers will support it.
Please look at documentation and wiki on http://www.xiph.org/ogg/
