SGGetChannelTimeScale

The SGGetChannelTimeScale function allows the sequence grabber to retrieve your channel's time scale.

pascal ComponentResult SGGetChannelTimeScale (SGChannel c,
                                              TimeScale *scale);

c

Identifies the channel connection for this operation.

scale

Contains a pointer to a time scale structure. Your channel component places information about its time scale into this structure.

DESCRIPTION

The time scale you return typically corresponds to the time scale of the media that has been created by your channel. Applications may use this time scale in their data functions (see the chapter "Sequence Grabber Components" in this book for more information about application-defined data functions).
