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 am looking to support playing DRM into custom player which is built using NDK C++ library as plugin which decodes, converts and then perform some image processing before final presentation. In this scenario, what is the best way to support DRM (I will use NDK's Crypto and DRM interfaces) given that documentation hints at only supporting MPEG-DASH format, which is not natively supported.
Clarify if any of my assumptions are incorrect or there are simple libraries (like libdash) which can solve the problem. Extreme solution in ExoPlayer but current infrastructure is built using C++ and NDK interface to leverage hardware decoders, which excludes that as an option.
If your image processing requires access to the raw image then unfortunately you won't (or you shouldn't!) be able to do this as encrypted video is designed to play via a secure media path which does not allow access to the raw video.
I want to develop an online video website and I think it's good to use DirectShow to implement some functionalities of video processing on that site. So my question is that can DirectShow be used on web application like the video website I just mentioned?
Yes, using ActiveX in Internet Explorer. But that's ugly and deprecated way.
HTML5 have access to webcams, so, are you sure that DirectShow is required?
I'm trying to develop the application based on native audio in gingerbread,
I executed the sample native audio program under the NDK ,but I'm not clear with
that. I need some example to learn how to use the openSL library.
Can any one suggest an example of open SL|ES based code ?
OpenSL ES documentation and that sample app are the best resources that are out there. Not to say that they're great, but they are definitely sufficient provided that you have the knowledge of object-oriented programming and audio. If you don't, those are the things you should look into first.
I need some links to record both microphone and audio in all the applications. I'm developing a audio recorder feature for an application.
I tried intercepting some APIs like IDirectSound and Wave API but I'm missing something since some applications are recorder and some others aren't.
Can someone send me a clue around this?
Best Regards.
In my compary we've developed an Audio Recorder SDK because it's very difficult to make all the hooks you need to intercept all the applications. You should hook MCI Wave API calls, IDirectSound interface and the new IAudioClient interface, part of the Windows Vista / Windows 7 Core Audio engine.
Our SDK supports Skype 4.x and 5.x, G-Talk and Msn. We've tested with other applications and it's working but we don't support them.
Additionally, we bring some UI features such as handling button clicks and get windows text using the SDK.
I hope this information can help you.
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.
