Method Documentation
| displayFrame | ( | self, | ||
| long | nowStamp, | |||
| long | outStamp | |||
| ) |
The signal is emitted whenever a frame should be displayed. nowStamp is the current time, outStamp tells the users what time the frame should be displayed with.
The relevant frames should be fetched and displayed using frameForTime method.
- Signal syntax:
QObject.connect(source, SIGNAL("displayFrame(qint64, qint64)"), target_slot)
| endOfMedia | ( | self ) |
This signal is emitted after the last frameReady signal of a media is emitted.
- Signal syntax:
QObject.connect(source, SIGNAL("endOfMedia()"), target_slot)
