9dwMinBitRate?4Specifies the minimum bit rate at the longest frame interval in units of bps at which the data can be transmitted.
13dwMaxBitRate4Specifies the maximum bit rate at the shortest frame interval in units of bps at which the data can be transmitted.
17dwMaxVideoFrameBufferSize?4Use of this field has been deprecated.Specifies the maximum number of bytes that the compressor will produce for a video frame or still image.
21dwDefaultFrameInterval?4デフォルトのフレームレート
25bFrameIntervalType?10:連続、1~255:The number of discrete frame intervals supported (n)
26dwMinFrameInterval?4bFrameIntervalType?=0の場合。Shortest frame interval supported (at highest frame rate), in 100 ns units.
30dwMaxFrameInterval?4bFrameIntervalType?=0の場合。Longest frame interval supported (at lowest frame rate), in 100 ns units.
