GetCSequenceKeyFrameRate
The GetCSequenceKeyFrameRate function lets you determine the current key frame rate of a sequence.
pascal OSErr GetCSequenceKeyFrameRate (ImageSequence seqID,
long *keyframerate);
seqID
- Contains the unique sequence identifier that was returned by the
CompressSequenceBegin function (described on page 3-100).
keyframerate
- Contains a pointer to a long integer that specifies the maximum number of frames allowed between key frames. Key frames provide points from which a temporally compressed sequence may be decompressed.
SEE ALSO
You can set the key frame rate of a sequence with the SetCSequenceKeyFrameRate function, described in the previous section.
