The DirectX.Capture namespace contains classes to capture video and audio to AVI files. See the Capture class for information on using this namespace.
| Class | Description |
|---|---|
| AudioCapabilities | Capabilities of the audio device such as min/max sampling rate and number of channels available. |
| AudioSource | Represents a physical connector or source on an audio device. This class is used on filters that support the IAMAudioInputMixer interface such as source cards. |
| Capture | Use the Capture class to capture audio and video to AVI files. |
| CrossbarSource | Represents a physical connector or source on an audio/video device. This class is used on filters that support the IAMCrossbar interface such as TV Tuners. |
| DeviceInUseException | Exception thrown when the device cannot be rendered or started. |
| DirectShowPropertyPage | Property pages for a DirectShow filter (e.g. hardware device). These property pages do not support persisting their settings. |
| Filter | Represents a DirectShow filter (e.g. video capture device, compression codec). |
| FilterCollection | A collection of Filter objects (DirectShow filters). This is used by the Capture class to provide lists of capture devices and compression filters. This class cannot be created directly. |
| Filters | Provides collections of devices and compression codecs installed on the system. |
| PropertyPage | A base class for representing property pages exposed by filters. |
| PropertyPageCollection | A collection of available PropertyPages in a DirectShow filter graph. It is up to the driver manufacturer to implement a property pages on their drivers. The list of supported property pages will vary from driver to driver. |
| Source | Represents a physical connector or source on an audio/video device. |
| SourceCollection | A collection of sources (or physical connectors) on an audio or video device. This is used by the Capture class to provide a list of available sources on the currently selected audio and video devices. This class cannot be created directly. This class assumes there is only 1 video and 1 audio crossbar and all input pins route to a single output pin on each crossbar. |
| Tuner | Control and query a hardware TV Tuner. |
| VfwCompressorPropertyPage | The property page to configure a Video for Windows compliant compression codec. Most compressors support this property page rather than a DirectShow property page. Also, most compressors do not support the IAMVideoCompression interface so this property page is the only method to configure a compressor. |
| VideoCapabilities | Capabilities of the video device such as min/max frame size and frame rate. |
| Enumeration | Description |
|---|---|
| TunerInputType | Specify the frequency of the TV tuner. |
