VideoPlayer widget is used to perform playback of video.
With VideoPlayer you can get results quickly and easily. You can do the standard playback tasks like PySide.phonon.Phonon::VideoPlayer.play() , PySide.phonon.Phonon::VideoPlayer.pause() ，和 PySide.phonon.Phonon::VideoPlayer.stop() , but also set a playback volume and seek - if the media and backend supports seeking.
VideoPlayer is provided for convenience and removes the need to create a media graph with a Phonon.MediaObject , Phonon.AudioOutput ，和 Phonon.VideoWidget . If you need functionality not supported by the player, you can build this graph yourself.
Keep in mind that when the VideoPlayer instance is deleted the playback will stop.
Note also that most of the functions in this class are asynchronous. For instance, a media source may not play immediately after you call the PySide.phonon.Phonon::VideoPlayer.play() 函数。

Phonon Module MediaObject
| 参数： |
|
|---|
Constructs a new video widget with a parent 使用 Phonon.VideoCategory as its category.
parent PySide.QtCore.QObject parent.
| 返回类型： | PySide.phonon.Phonon::AudioOutput |
|---|
Returns the audio output object being used by the player.
| 返回类型： | PySide.QtCore.qint64 |
|---|
Get the current time (in milliseconds) of the file currently being played.
| 返回类型： | PySide.QtCore.bool |
|---|
Returns true if it is currently paused; otherwise returns false if it is currently playing or stopped.
| 返回类型： | PySide.QtCore.bool |
|---|
Returns true if it is currently playing; otherwise returns false if it is currently stopped or paused
| 参数： | source – PySide.phonon.Phonon::MediaSource |
|---|
| 返回类型： | PySide.phonon.Phonon::MediaObject |
|---|
Returns the media object being used by the player.
The media object can be accessed directly instead of using the VideoPlayer s convenience functions, e.g., PySide.phonon.Phonon::VideoPlayer.play() and PySide.phonon.Phonon::VideoPlayer.stop() . It is also possible to give the object to other Phonon widgets, e.g., a Phonon.SeekSlider 或 Phonon.VolumeSlider .

MediaObject.pause()
| 参数： | source – PySide.phonon.Phonon::MediaSource |
|---|
Continues playback of paused media. Restarts playback of a stopped (or newly loaded) media.
另请参阅
MediaObject.play() PySide.phonon.Phonon::VideoPlayer.play()
| 参数： | ms – PySide.QtCore.qint64 |
|---|
Seeks to the requested time. Note that the backend is free to ignore the seek request if the media source isn't seekable; you can check this by asking the media object of the VideoPlayer .
player->mediaObject()->isSeekable();
ms parameter is the time in milliseconds from the start of the media.
The call is asynchronous, so PySide.phonon.Phonon::VideoPlayer.currentTime() can still be the old value right after this method was called. If all you need is a slider that shows the current position and allows the user to seek, use the class SeekSlider .
