Indicates video compression capabilities.

Syntax 

typedef enum {
  CompressionCaps_CanQuality  = 0x01,
  CompressionCaps_CanCrunch   = 0x02,
  CompressionCaps_CanKeyFrame = 0x04,
  CompressionCaps_CanBFrame   = 0x08,
  CompressionCaps_CanWindow   = 0x10
} CompressionCaps;

Elements

CompressionCaps_CanQuality

Video compressor supports the IAMVideoCompression::put_Qualityand IAMVideoCompression::get_Qualitymethods.

CompressionCaps_CanCrunch

Video compressor can compress video to a specified data rate. If the compressor has this capability then the output pins media type will contain the data rate in the VIDEOINFOHEADERstructure's dwBitRatemember. The only way to set the data rate is to set dwBitRate.

CompressionCaps_CanKeyFrame

Video compressor supports the IAMVideoCompression::put_KeyFrameRateand IAMVideoCompression::get_KeyFrameRatemethods.

CompressionCaps_CanBFrame

Video compressor supports the IAMVideoCompression::put_PFramesPerKeyFrameand IAMVideoCompression::get_PFramesPerKeyFramemethods.

CompressionCaps_CanWindow

Video compressor supports the IAMVideoCompression::put_WindowSizeand IAMVideoCompression::get_WindowSizemethods.
