public static interface QuickTimeLibrary.QTVisualContextImageAvailableCallback
- extends Callback
QTVisualContextImageAvailableCallback
Summary:
User-defined callback function to recieve notifications when a
new image becomes available.
Discussion:
Due to unpredictible activity, such as user seeks or the arrival
of streaming video packets from a network, new images may become
available for times supposedly occupied by previous images.
Applications using the CoreVideo display link to drive rendering
probably do not need to install a callback of this type since
they will already be checking for new images at a sufficient rate.
Parameters:
visualContext:
[in] The visual context invoking the callback.
timeStamp:
[in] Time for which a new image has become available.
refCon:
[in] User-defined value passed to
QTVisualContextSetImageAvailableCallback.
