ltmmCapture_Object_AudioCaptureFilter |
Specifies the audio device filter. |
ltmmCapture_Object_VideoCapturePin |
Specifies the video capture pin. |
ltmmCapture_Object_AudioCapturePin |
Specifies the audio capture pin. |
ltmmCapture_Object_VideoPreviewPin |
Specifies the video preview pin. |
ltmmCapture_Object_AudioPreviewPin |
Specifies the audio preview pin. |
ltmmCapture_Object_TVTuner |
Specifies the TV tuner. |
ltmmCapture_Object_TVAudio |
Specifies the TV audio controls. |
ltmmCapture_Object_VideoCrossbar |
Specifies the video crossbar. |
ltmmCapture_Object_AudioCrossbar |
Specifies the audio or secondary crossbar. |
ltmmCapture_Object_VideoCompressor |
Specifies the currently selected video compressor Also known as an encoder Also known as compressor, this is a module or algorithm to compress data. Playing that data back requires a decompressor, or decoder. , this is a module or algorithm to compress data. Playing that data back requires a decompressor, or decoder Also known as a decompressor, this is a module or algorithm to decompress data. . . |
ltmmCapture_Object_AudioCompressor |
Specifies the currently selected audio compressor. |
ltmmCapture_Object_TargetFilter |
Specifies the target filter. |
ltmmCapture_Object_VideoRenderer |
Specifies the preview video renderer The DirectShow component responsible for playing the video. Some renderers might have useful settings you can adjust if you have problems playing the video. . |
ltmmCapture_Object_AudioRenderer |
Specifies the preview audio renderer The audio device that will play the sound. This is usually your sound card. Some computers have more than one sound playback device. You choose which sound playback device will play the sound by selecting the corresponding audio renderer. . |
ltmmCapture_Object_VideoDecompressor |
Specifies the video decompressor. This is usually present when capturing from compressed formats, like DV DV stands for Digital Video and has been defined in "Specification of Consumer-use Digital VCRs" (aka the Blue Book). camcorders, and recompressing. |
ltmmCapture_Object_AudioDecompressor |
Specifies the audio decompressor. |
ltmmCapture_Object_Splitter |
Specifies the splitter. This is usually present when capturing interleaved video, like DV video, and recompressing. |
ltmmCapture_Object_VideoCompressorOutputPin |
Specifies the video compressor output pin. |
ltmmCapture_Object_AudioCompressorOutputPin |
Specifies the audio compressor output pin. |
ltmmCapture_Object_Sink |
Specifies the sink (writer) object. If the target format type is ltmmCapture_TargetFormat_DVD, this specifies the DVD writer object. |
ltmmCapture_Object_TargetAVMux |
Specifies the multiplexer for current target format. |
ltmmCapture_Object_TargetVideoCompressor |
Specifies implicit video compressor for the current target format. If the target format type is ltmmCapture_TargetFormat_FLV_H264, this specifies the H264 encoder. |
ltmmCapture_Object_TargetAudioCompressor |
Specifies implicit audio compressor for the current target format. If the target format type is ltmmCapture_TargetFormat_FLV_H264, this specifies the AAC encoder. |
ltmmCapture_Object_SelAudioProcessor |
Specifies the first selected audio processor. Additional processors may be specified by adding the processor's collection index to this constant. A maximum of 256 processors may be specified. |
ltmmCapture_Object_SelVideoProcessor |
Specifies the first selected video processor. Additional processors may be specified by adding the processor's collection index to this constant. A maximum of 256 processors may be specified. |
ltmmCapture_Object_PrevAudioProcessor |
Specifies the first preview audio processor. Additional processors may be specified by adding the processor's collection index to this constant. A maximum of 256 processors may be specified. Preview processors affect only the preview stream, not any captured video. |
ltmmCapture_Object_PrevVideoProcessor |
Specifies the first preview video processor. Additional processors may be specified by adding the processor's collection index to this constant. A maximum of 256 processors may be specified. Preview processors affect only the preview stream, not any captured video. |
