CaptureObject Enumeration

Summary

The CaptureObject enumeration values define objects that can be obtained using the CaptureCtrl.GetSubObject method.

Syntax

C++/CLI

public enum CaptureObject

public enum class CaptureObject

Members

Value	Member	Description
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.
8	TVAudio	Specifies the TV audio controls.
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.
14	VideoRenderer	Specifies the preview video renderer The DirectShow component responsible for playing the video.
15	AudioRenderer	Specifies the preview audio renderer The audio device that will play the sound.
16	VideoDecompressor	Specifies the video decompressor.
17	AudioDecompressor	Specifies the audio decompressor.
18	Splitter	Specifies the splitter.
19	VideoCompressorOutputPin	Specifies the video compressor output pin.
20	AudioCompressorOutputPin	Specifies the audio compressor output pin.
21	Sink	Specifies the sink (writer) object.
22	TargetAVMux	Specifies the target AV multiplexer.
23	TargetVideoCompressor	Specifies the target video compressor.
24	TargetAudioCompressor	Specifies the target audio processor.
25	SplitterSubtitles	Specifies the splitter (demultiplexer) subtitles object.
256	SelAudioProcessor	Specifies the first selected audio processor.
512	SelVideoProcessor	Specifies the first selected video processor.
768	PrevAudioProcessor	Specifies the preview audio processor.
1024	PrevVideoProcessor	Specifies the preview video processor.
