Project Description
The VideoRendererElement allows for high-performance, custom video in WPF.
With the VideoRendererElement, a developer can update a pixel buffer or video media sample and have it render in WPF space at MediaElement speed. It is compatible with GDI, DirectShow and direct pixel updates.

FAQ
Why is the VideoRendererElement? The MediaElement works fine for me.
The MediaElement does work fine for most people. The problem is that the MediaElement only allows you to supply a Uri source. The developer does not have any flexibility to create their own custom video solutions.

Can't I just use the InteropBitmap and update that buffer?
You can. Sure. The problem is that execution path is many times slower than MediaElement (and therefore VideoRendererElement) and you get tearing in the video. There is a new WriteableBitmap that is comming in .NET 3.5 summer update, but that probably won't be performant or optimized for video.

What is a FOURCC?
A FOURCC is a four character codec code. If you are just doing uncompressed updates, you do not need one. When you load up a media file, DirectShow uses the FOURCC to determine what codecs are compatible with your media. For example, there is a Motion-JPEG codec that comes with Windows. It is configured to be loaded with a FOURCC of MJPG.

My video is upside down or sideways! What do I do?
If you are supplying uncompressed samples, like a Bitmap, when you initialize the renderer, supply a negative value for the width or height will fix that.

UPDATED WIKI: Feature List

jmorrill — Thu, 10 Apr 2008 08:21:13 GMT

Feature List

Single componentized WPF element
Simple API. You do not need to know DirectShow! Though you can still use DirectShow if you like, just pass the output of a DirectShow graph (via SampleGrabber if needed) to the VideoRendererElement for output.
You can write uncompressed or compressed samples to the VideoRendererElement. Because I use DirectShow in the background, I allow a developer to copy not only uncompressed RGB pixels over, but YUV or even MPEG4, JPG, WMV, etc samples to be decompressed.
This can also be used as a high-performance "WriteableBitmap" if you wish. Now you can use your old GDI code again.
