cbTotalFileSize
Size of the file, in bytes. If the total size is unknown, set this member to -1.cbPlayableDataSize
Size of the playable media data in the file, excluding any trailing data that is not useful for playback. If this value is unknown, set this member to -1.prgBuckets
Pointer to an array of MF_LEAKY_BUCKET_PAIR structures. Each member of the array gives the buffer window for a particular bit rate.cBuckets
The number of elements in the prgBuckets array.qwNetBufferingTime
Amount of data to buffer from the network, in 100-nanosecond units. This value is in addition to the buffer windows defined in the prgBuckets member.qwExtraBufferingTimeDuringSeek
Amount of additional data to buffer when seeking, in 100-nanosecond units. This value reflects the fact that downloading must start from the previous key frame before the seek point. If the value is unknown, set this member to zero.qwPlayDuration
The playback duration of the file, in 100-nanosecond units. If the duration is unknown, set this member to zero.dRate
Playback rate.
