The samples only provide partial and very basic functionality.

EXPERIMENTAL! don't use it in production quality code.

Note, the few settings can only be done once at startup, and writing to the AVI file starts immediately. The last sample, CaptureNET can be used to capture a live video stream to disk.

The sample also supports the IAMTVTuner interface of a TV card, so you can switch the TV tuner channel. By pressing the 'Grab' toolbar-button, you can capture a still picture to a 24-Bit RGB bitmap file! It shows a live video stream from a capture device like DV cam, web cam or TV card in a preview window. The most complex sample provided is SampleGrabberNET. Then, the C# sample uses the DirectShow DVD interfaces to watch the movie. It plays the known video and audio file formats of DirectShow like avi, mpg, wav, mid etc.įor the next sample, DVDPlayerNET you must have a third-party DVD codec installed, like WinDVD or PowerDVD. The first sample included in the download is PlayWndNET. \SampleGrabberNET\ // picture grabber Playback \PlayWndNET\ // simple media file playback \CaptureNET\ // video stream capture sample

\QEdit.cs // grabber interfaces from qedit.idl \DsUuids.cs // UUIDs and CLSIDs from uuids.h \DsUtils.cs // utility classes, SDK Common sources \DsDVD.cs // DVD interfaces from dvdif.idl \DsDevice.cs // device enumerator, helper functions \DShowNET\ // the DirectShow interface definitions : One typical rewrite of an IDL interface in C# looks like this :

You have to understand Interop to use it correctly.

Much of initial work for rewriting the interfaces.

We can directly use the (documented) interfaces without limitations, no 'wrapper classes'.

DirectShow methods for simple playback/capturing are not time-critical.

Most DirectShow interfaces are not very complex.

I chose the second strategy for this reasons :

Rewrite all the interfaces from IDL to e.g.

Use 'Managed Extensions for C++', as done e.g.

We have to use Interop with one of this approaches: NET, there is no direct way to access the custom DirectShow interfaces. While using the VB6 components with the provided type library is easy with. NET, as described in this CodeProject article: DirectShow MediaPlayer in C# (Daniel Strigl). You can use the DirectShow playback components for VB6 with.

DirectShow VB components - designed for VB6, provides a type library.

DirectShow custom interfaces - mainly for C++ programmers.

Please install the latest version, this article doesn't support anything except 8.1 :Īgain, I will not describe any DirectShow interfaces, you have to know them by installing the SDK for C++, reading the SDK documentation and understanding the SDK samples!ĭirectShow is exposed as COM components and interfaces, at these two 'levels': DirectShow is available with the current DirectX version 8.1(b) for Windows 98/ME/2000 and included in XP.

NET Interop technologies! DirectShowĭirectShow is a standardized Microsoft Win32 API to use any compliant movie or video device from your application. Note, this article doesn't save you from reading the detailed DirectShow SDK documentation! I will not explain DirectShow, only some of the used. This includes simple media playback, playing DVD discs, capturing video streams to disk and a sample picture grabber.
