C# - Play MP4 from Embedded Resources in Background

I have added a MP4 file to the Project resources and changed the building to Embedded Resource.
Now I want to load this mp4 file from the embedded resources and play it on the form (for example in a picturebox).
I know it's possible with Windows Media Player for example but I haven't found a way to play the mp4 from embedded resources without having to extract into a folder first.
Something like that would be awesome:
axWindowsMediaPlayer1.URL = global::PlayerUI.Properties.Resources.MP4File;
But that doesn't work of course. Is there a method like that?

Extracting and splitting a MP3 audio stream from an AVI file

I want to develop a desktop application by programming in C# and using the .Net framework 4.
The goal of my application is to extract a MP3 audio stream from a supplied AVI file.
I have learned from the Internet that an AVI file is a container and it might contain different audio streams.
If the supplied AVI file contains one MP3 audio stream at least then I want to extract it and split it.
I want to split the MP3 audio stream into MP3 audio parts identified with a start time and an end time.
I have looked on the Internet for any .Net library I could use but without success.
Does someone know what documented .Net library would be useful ?

Maybe you can try this:
Simple C# Wrapper for the AviFile Library
It is targeted at AVI video but there might be some clues as how to use the same methods to extract the audio only.
Either use it as-is or use the example to incorporate what you need into your own code.

Since tools for this task already exist, I see no point in creating another one unless you're curious about how to do this yourself and learn something new.
If so, using a ready-made library would defeat the entire idea of learning something which is why I strongly recommend you try implementing the splitter yourself.
You can find descriptions of the AVI file format online, that should get you started.

Create an .avi file from a list of bitmap images

I am currently trying to make a screen recorder.
I made list of bitmap images and want to put them in an .avi file.
Is there anyway to do that in C#?
note: i'm a novice, so keep things simple

Try SharpAvi library. Its sources include a sample screen recording application.

Try this site which has downloadable examples as well: A Simple C# Wrapper for the AviFile Library.

How to save video in Silverlight 5

Is it possible to capture video and audio in Silverlight5 and save it as movie in any video format?

Silverlight 5 can automatically detect video and audio capture devices, which you can open operations on using the System.Windows.Media.CaptureDeviceConfiguration class and associated classes.
http://chris.59north.com/post/Audio-recording-and-encoding-in-Silverlight.aspx has info on how to use those classes to save the audio to a Stream (as well as compressing it), which you can then save to disk.
http://www.dotnetfunda.com/articles/article1751-how-to-access-a-video-and-snap-a-picture-from-webcam-in-silverlight.aspx has similar info on how to access video and save images from webcams on to disk using Silverlight.
Pro Silverlight 5 in C# (excerpt on Google Books) has more information on how to do this.

I have been doing quite a lot of searching and I have yet to find any samples of anyone actually saving video. The best I have been able to come up with is saving a sequence of images. That doesn't really sound like a good solution

ExpressionMediaPlayer to play .mpeg

I'm trying to write a Silverlight application that reads a media file from a database (most likely a .mpeg or .mpg) and play it on the fly using either a Silverlight MediaPlayer or ExpressionMediaPlayer. When I try using Expression Media Player it plays .wmv and .mp4 files but NOT .mpeg or .mpg file extensions. Is this even possible? If so, HOW?!
I tried going a different route originally where I wrote a Service to Encode the file using a LiveJob and then play it on the ExpressionMediaPlayer from the port using mms://localhost:8080 but I couldn't figure out how to use that to Play/Pause the video. It just ran through once and stopped. Any suggestions on that?
I'm using Expression Encoder 3 & Silverlight 4 by the way.

i think you're out of luck, check out this page from msdn.
You are going to have to re-encode the file if you want it to play in Silverlight.
