directshow

Ok I have been at this for 2 days and need help with this last part. I have a Microsoft LifeCam Cinema camera and I use the .NET DirectShowLib to capture the video stream. Well actually I use WPFMediaKit, but I am in the source code of that dealing directly with the direct show library now. What I have working is: - View the video output of the camera - Record the video output of the camera in ASF or AVI (the only 2 MediaType's supported with ICaptureGraphBuilder2) The problem is: I can save it as a .avi. This works fine and at a resolution of 1280x720 but it saves the file in RAW output.

I've read through the MSDN documentation on DirectShow and it's still confusing. I feel like I need more context for what the objects are: Graphs, Pins, Filters...etc. A Google search doesn't give me much to work with. What do I need to grok DirectShow? EDIT: The wikipedia page on DirectShow does a pretty good job. MSDN Magazine has a nice article in their July 2002 Issue: DirectShow: Core Media Technology in Windows XP Empowers You to Create Custom Audio/Video Processing Components Pascal Mignot from Université de Reims has gathered information from MSDN documentation into a single document ,

I have a directory of bitmaps that are all of the same dimension. I would like to convert these bitmaps into a video file. I don't care if the video file (codec) is wmv or avi. My only requirement is that I specify the frame rate. This does not need to be cross platform, Windows (Vista and XP) only. I have read a few things about using the Windows Media SDK or DirectShow, but none of them are that explicit about providing code samples. Could anyone provide some insight, or some valuable resources that might help me to do this in C#? At the risk of being voted down, I'll offer a possible

I want to develop a virtual webcam driver which from User mode I'll pass image to it and it will display as webcam output. I don't want to use DirectX filter and CSourceStream etc. Because they don't work on some programs which doesn't use DirectX for capturing webcam image. I have to write a kernel mode device driver so. Any ideas? I tried testcap from DDK samples, but it doesn't process image from user mode and doesn't get any input, just it displays 7 colors in webcam... Any help would be greatly appreciated. Thanks Thank you all! I tried code from here: http://tmhare.mvps.org/downloads.htm

How to change Filter Properties programmatically? I am using a filter AAC encoder , and I can manually change its bitrate in graphedit by right clicking on the filter and entering the bitrate value. Is it possible to do the same through code? Please give me valuable suggestions and if possible with code. You do this via private filter-specific interface. You need to refer to filter documentation or SDK to get details on this ( VSS Tech Support ). Sometimes you can obtain the necessary information from type library. See: Controlling variables in filter remotely with out property page, How can I

I have found an example for accessing a webcam in C#. The example uses the DirectShow.NET library. I have tried to understand the code, but so far the only thing I could figure out is that somehow the usercontrol calls directshow to draw directly to the surface of the user control. I want to access each frame and put it into a Bitmap object. How can I tell when a new frame arrived? How can I capture this new frame into a Bitmap Object? This might be simple to answer if you know your way around DirectShow.NET. Shay Erlichmen You will need to use the ISampleGrabber interface there are many c++
