Media foundation is the recommended technology by Microsoft and it has really supported it by a lot of samples and explanation but all are with the native code

I found a wrapper in sourceforge make me able to use Media Foundation with C# but while I am reading people talk about not every thing can be done by the managed code

I have some tasks to do with MF:

  1. Capture alive video
  2. change resolution and baud rate
  3. Encode video
  4. decode video

Can I use .net in these tasks or I have to use the native code?Is there samples help (please don't mention msdn one from them)?

    Welcome to StackOverflow. Media Foundation is great to work with, and performs very well. If your requirements include real-time, you will be best served by writing your own C++/CLI wrapper to orchestrate the overall process. I assume you mean bit rate (as opposed to baud rate). Are you wanting to capture a webcam stream? Are you encoding /decoding to possibly more than one media type? Is audio included? – Jeff Feb 02 '15 at 20:30
  • @Jeff Thanks for your answer yes I want to capture a webcam stream and while I am capturing it I encode frames each time cycle and append it to the desk,I can put in one container not many(may be byte stream also without container).I need video only I am not caring about audio at all – tulipe Feb 04 '15 at 06:18

    I'm no media foundation expert but I have found the best way to interact between it an C# is to use Managed C++. I've managed to capture live video from Media Foundation to my C# WPF application. The main C++ class is here but be warned again that I'm no expert on MF http://sipsorcery.codeplex.com/SourceControl/latest#sipsorcery-media/SIPSorcery.Media/MFVideoSampler.cpp. – sipsorcery Feb 06 '15 at 10:56

The Media Foundation .NET C# wrapper can work well for all those tasks you mentioned. I've used it personally to implement the capture, resizing, and encoding, and I imagine decoding shouldn't be too hard either.

The project does have some examples you can download but I find them rather lacking. The wrapper is so close to the C++ implementation that it's not too hard to use C++ examples and just port the logic to C#. I used the following as a reference and found it to be very valuable: https://github.com/sipsorcery/mediafoundationsamples

    Where do you find the Media Foundation .NET C# wrapper? Is there an official release or are you referring to the "snarfle" project at source forge? – Mark Lauter Jan 16 '19 at 03:38
