import sys
from araviq6 import PlayerProcessWidget, VideoFrameWorker
from araviq6.util import get_data_path
class FlipWorker(VideoFrameWorker):
    def processArray(self, array):
        return array[::-1]
def runGUI():
    app = QApplication(sys.argv)
    w = PlayerProcessWidget()
    w.setWorker(FlipWorker())
    w.setSource(QUrl.fromLocalFile(get_data_path('hello.mp4')))
    w.show()
