Elements
CompressionCaps_CanQuality
Video compressor supports the IAMVideoCompression::put_Quality and IAMVideoCompression::get_Quality methods.
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 VIDEOINFOHEADER structure's dwBitRate member. The only way to set the data rate is to set dwBitRate.
CompressionCaps_CanKeyFrame
Video compressor supports the IAMVideoCompression::put_KeyFrameRate and IAMVideoCompression::get_KeyFrameRate methods.
CompressionCaps_CanBFrame
Video compressor supports the IAMVideoCompression::put_PFramesPerKeyFrame and IAMVideoCompression::get_PFramesPerKeyFrame methods.
CompressionCaps_CanWindow
Video compressor supports the IAMVideoCompression::put_WindowSize and IAMVideoCompression::get_WindowSize methods.
