0 | FilterGraph | Specifies the filter graph. |
1 | VideoCaptureFilter | Specifies the video device filter. |
2 | AudioCaptureFilter | Specifies the audio device filter. |
3 | VideoCapturePin | Specifies the video capture pin. |
4 | AudioCapturePin | Specifies the audio capture pin. |
5 | VideoPreviewPin | Specifies the video preview pin. |
6 | AudioPreviewPin | Specifies the audio preview pin. |
7 | TVTuner | Specifies the TV tuner. |

9 | VideoCrossbar | Specifies the video crossbar. |
10 | AudioCrossbar | Specifies the audio or secondary crossbar. |
11 | VideoCompressor | Specifies the currently selected video compressor, known as an encoder or compressor, a module or algorithm to compress data. |
12 | AudioCompressor | Specifies the currently selected audio compressor. |
13 | TargetFilter | Specifies the target filter.Note:If the target filter is a multiplexer or sink, it is advisable to use TargetFormat.GetCacheObject instead of CaptureCtrl.GetSubObject. Target filters are not added to the capture graph until the capture graph is built using CaptureCtrl.ReadyCapture or CaptureCtrl.StartCapture. At this point, the graph is in running state. Some multiplexers or sinks might not be able to change some settings in running mode. By default, when you stop the capture, the multiplexer and sink are destroyed. As a result, the only way to change their settings in stopped mode is to create them before the capture starts. You can do that by first setting the TargetFormat.UseFilterCache property to true and then retrieving the objects using TargetFormat.GetCacheObject. |
