Video¶
The Video
widget is used to display video files and streams.
Depending on your Video core provider, platform, and plugins, you will
be able to play different formats. For example, the pygame video
provider only supports MPEG1 on Linux and OSX. GStreamer is more
versatile, and can read many video containers and codecs such as MKV,
OGV, AVI, MOV, FLV (if the correct gstreamer plugins are installed). Our
VideoBase
implementation is used under the
hood.
Video loading is asynchronous - many properties are not available until the video is loaded (when the texture is created):
def on_position_change(instance, value):
print('The position in the video is', value)
def on_duration_change(instance, value):
print('The duration of the video is', value)
video = Video(source='PandaSneezes.avi')
video.bind(position=on_position_change,
duration=on_duration_change)

play
is aBooleanProperty
