media transcoding, codec in c#

I would be developing a media player app in hopefully wpf but i am having trouble with a few aspects.
I know that i can do some basic stuff with audio n video using MediaElement class in c# but i was wondering that
1. i also need to stream online videos and save them in different qualities(resolution) and formats and also might extrfact audio from them
2. I would be needing to convert and play existing files on my system.
3. Video/screen capture
4. Substitles etc.
5. Equalizer
I heard about ffmpeg
But i am confused that if i could use it with c#.
So help me if there is something better to help with max. Of the issues i have here. And what are the things i need to read about. Is there any tutorial that would help me out.

Windows Phone 8 - Playing streamed audio (internet radio station)

I am trying to make an application that would play an audio stream (mp3) from the following URL http://icecast6.play.cz/radio1-128.mp3. I am struggling to get it working. Is there any default support for cases like these? That the content is continuously streamed?
I have tried to use Background Audio Agent and set Media Element but none of that has been working for me. Would Background Audio Streamer be an option for me? I would be happy for any similar example that I would use to my advantage.
Thank you

I found phonesm project on codeplex that provides great examples and functionality for implementing internet audio streaming.

You need to use BackgroundAudioPlayer by creating another project and adding its reference to your project.

You can use Microsoft player framework.

c# text/winForm overlay video games like xfire,PIX,steam,fraps etc

I know there is plenty of post about this topic , however I've been looking for a solution to this for months. I checked about 300 posts on google about this. The only good thing I found was a c++ program that was drawing a colored rectangle over League's window. I am not very familiar with directx. My program is in c# and I would to write text or if possible make a winForm visible over a full screen video game.
I tried every single sample found on forums but 50% of them are old and links aren't working anymore.
Hope you guys can help me.
Thank you,
Kevin

You can detect directx games by looking which dlls are importing.there is certain dlls like http://www.toymaker.info/Games/html/d3dx_dlls.html.

Xna AudioEmitter & AudioLIstener

Can you tell me how exactly does that thing works. I mean how audioListnere knows, that audioEmitter is playing something ? We are making game with few friends, and i am responsible for the audio, and i am collection all kind of knowledge. I apprieciate all kind of help.

Here is an article about Dynamic Audio from XNA Creators website. They also have a 3D Audio sample.
There is also the SoundLab with 170 audio files which maybe a good starting point.

C# Video Playback

I'm looking at trying to create a simple 'slider puzzle' game. You've seen the ones, you have an image and you shuffle the tiles.
However, I want to make one that will play back videos instead. What I'm trying to determine is whether it's possible to playback a video in C# and render the video on different controls (probably buttons, or panels). I've spotted the Microsoft.DirectX.AudioVideoPlayback classes but haven't found much documentation on them yet.
So to throw it up in the air, is this going to be possible to do without too much difficulty? Are there any useful (free) libraries that might help me along?

Have a look at DirectShowNet that wraps the DirectShow API, in the samples page there is a sample called PlayWnd the shows how to play a video file.

Depending upon how large and how long your video sources are, you could accomplish this very simply by first converting your videos to animated GIFs. A .Net PictureBox control will display and animate a GIF automatically, and you could easily use PictureBoxes for your tiles.
One big advantage of this approach is that (thanks to Mono) your application could work unaltered on Windows, Mac and the iPhone (also Linux and a couple others).
