Is it possible to alter the chromium browser to add support for h264 codecs that youtube is using for live streams, for example
https://www.youtube.com/watch?v=KF47Za1lfjM
These are unsupported in the browser widget as the chromium instance does not support the streaming. Is it a difficult thing to update the chromium instance with another version which supports the streams?
I hope you post this as a bug or feature request in http://quality.livecode.com/. You are more likely to get an answer there from someone who does the builds.

I have an app that I have written using Xamarin forms. I wanted to know if there is any media
class I could use to record audio as well as stream audio from a server. All articles I have found on the web are platform specific so far.
thanks in advance
There currently isn't any audio support in Xamarin.Forms. You will need to write platform specific code for handling the audio and use the XF DependencyService (or something similar) to call it from your shared code.
I'm trying to get a video playing on Chromecast - it's available as an MS Smooth Streaming manifest (example), but I can't specify format=mpd-time-csf (example), as it's not available in that format.
Directly passing the manifest URL to the Chromecast doesn't work yet, but will be available for the final SDK release, as stated by Les Vogel here:
Playing Smoothstreaming URL by providing Manifest file of smoothstreaming to Chromecast device
As I understand it can play dash/smooth videos by embedding the dash.js player into the receiver app. However, dash.js only plays smooth streaming videos if (format=mpd-time-csf) is specified - normal smooth manifests don't work.
Does this mean that in its current state, Chromecast only supports smooth video in the mpd-time-csf format? I assume the Netflix app uses Smooth for its Chromecast app - is this how they're doing it?
Currently, unless you write your own (javascript) player than can handle smooth streaming (i.e. parse manifest, fetch fragments, use MSE extension, etc), you cannot play smooth streaming content on chromecast.
Ali.
Just following up my own question in case anyone stumbles across this from Google - with the release of the SDK SmoothStreaming should be playable out of the box with the Media Player Library: https://developers.google.com/cast/docs/player.
Google has taken up the implementation of WebRTC in Chrome very seriously as indicated by the frequent updates in the Canary and Beta channel of Chrome. Are there any other browsers who are upto implementing this?
Firefox/IE/Opera are working on it. No word from Apple/Safari or Microsoft/IE, although IE is unlikely at best, because they're working on their own standard unfortunately. Crazier things have happened, but I wouldn't count on it. Apple has been fairly mum on the subject.
If you want support for those other browsers, we built a solution for it # Frozen Mountain (I work there) using IceLink.
Opera Mobile does offer support to WebRTC. And according to this article, Mozilla isn't all that far behind either. Ericsson Labs has their own custom browser which supports WebRTC. But it runs only on Ubuntu as of now. WebRTC itself is still under development and I'm sure that we can see complete support from all major browsers in some time.
Mozilla is far along in implementing WebRTC, and we're leading the design and implementation of DataChannels within WebRTC, as well as Identity work. We're working on a project-specific repo right now (alder), but pieces have already moved over into mozilla-central, such as initial support for getUserMedia.
What's the simplest way to setup a chrome extension to record audio from the microphone?
I see there is a working experimental speech input API but how come you don't have access to the recorded file? Seems like hooking up into that should be simple enough, as it's a step earlier in the process, no? Especially as there is also a text-to-speech API, so you could effectively record into text and then have the computer speak it back out, but unless you want a standard voice, how lame, redundant and prone to error is that?
Then there seem to be flash solutions like this but how can I use that in a chrome extension without having to setup anything server-side? (since I don't actually need to send anything to a server--it's all local and client-side)
Is NPAPI a possibility? Is there such a plugin ready-made?
Don't know of other possible alternatives (HTML5 isn't ready yet, it seems) but I welcome anything functional and simple to implement and hook into a chrome extension.
Finally a native solution appeared: Introducing getUserMedia
You cannot use the speech input API, since it will record only the microphone. Okay, you can grab the speakers like that, but it's clearly not the solution.
Using a NPAPI plugin is a solution. You'll can identify the sound made by a particular tab and after record that source, but it is no longer web dev.
I'm building a web application to support RPG games, like Dungeons & Dragons. It's
like a AJAX chat room with dice rollers, avatars, shared information, character sheets and
so on...
One of my desired features is to let the game master to play music to all game members.
How can I implement that?
I'm building the application with Asp.NET, using C# 3.5.
In the client side I'm using jQuery (latest version).
I intend to avoid Flash and Silverlight (even if the music resource will be available to
some browsers only).
I tryed to use ogg format, but I don't know how to make it work with my own audio
files. Do I need to implement a stream or something?
The application already is online. If someone want to see it, let me know. But
it's only available in portuguese (Brazil).
Any tip will be apreciated.
You have a better chance of integrating the sound if its a mp3, then using javascript or HTML5.
HTML5 Code:
<audio src="anyone-there.mp3" autoplay controls></audio>

HTML5 is not supported by many browsers, so using a javascript to play the sound would be alot better.
