Namespace: Phonon
Detailed Description
\class VideoPlayer videoplayer.h Phonon/VideoPlayer Playback class for simple tasks.
With %VideoPlayer you can get results quickly and easily. You can do the standard playback tasks like play, pause and stop, but also set a playback volume and seek (there's no guarantee that the seek will work, though).
Keep in mind that when the %VideoPlayer instance is deleted the playback will stop.
A play and forget code example:
VideoPlayer *player = new VideoPlayer(parentWidget); connect(player, SIGNAL(finished()), player, SLOT(deleteLater())); player->play(url);

Method Documentation
| __init__ | ( | self, | ||
| Phonon.Category | category, | |||
| QWidget | parent=0 | |||
| ) |
Constructs a new %VideoPlayer instance.
- Parameters:
-
category The category used for the audio output device.
- Parameters:
-
parent The QObject parent.
| __init__ | ( | self, | ||
| QWidget | parent=0 | |||
| ) |
Constructs a new video widget with a parent using Phonon.VideoCategory as its category.
- Parameters:
-
parent The QObject parent.
| Phonon.AudioOutput audioOutput | ( | self ) |
getter for the AudioOutput.
| long currentTime | ( | self ) |
Get the current time (in milliseconds) of the file currently being played.
| finished | ( | self ) |
This signal is emitted when the playback finished.
- Signal syntax:
QObject.connect(source, SIGNAL("finished()"), target_slot)
| bool isPaused | ( | self ) |
- Returns:
- true if it is currently paused
- Returns:
- false if it is currently playing or stopped
| bool isPlaying | ( | self ) |
- Returns:
- true if it is currently playing
- Returns:
- false if it is currently stopped or paused
| load | ( | self, | ||
| Phonon.MediaSource | source | |||
| ) |
Starts preloading the media data and fill audiobuffers in the backend.
When there's already a media playing (or paused) it will be stopped (the finished signal will not be emitted).
| Phonon.MediaObject mediaObject | ( | self ) |
getter for the MediaObject.
| pause | ( | self ) |
Pauses the playback.
| play | ( | self, | ||
| Phonon.MediaSource | source | |||
| ) |
Play the media at the given URL. Starts playback as fast as possible. This can take a considerable time depending on the URL and the backend.
If you need low latency between calling play() and the sound actually starting to play on your output device you need to use MediaObject and be able to set the URL before calling play(). Note that
audioPlayer->load(url); audioPlayer->play();doesn't make a difference: the application should be idle between the load and play calls so that the backend can start preloading the media and fill audio buffers.
| play | ( | self ) |
Continues playback of a paused media. Restarts playback of a stopped media.
| seek | ( | self, | ||
| long | ms | |||
| ) |
Seeks to the requested time. Note that the backend is free to ignore the seek request if the media source isn't seekable.
- Parameters:
-
ms Time in milliseconds from the start of the media.
| setVolume | ( | self, | ||
| float | volume | |||
| ) |
Sets the volume of the output as voltage factor.
1.0 means 100%, 0.5 means 50% voltage/25% power, 0.0 means 0%
| stop | ( | self ) |
Stops the playback.
| long totalTime | ( | self ) |
Get the total time (in milliseconds) of the file currently being played.
| Phonon.VideoWidget videoWidget | ( | self ) |
getter for the VideoWidget.
| float volume | ( | self ) |
This is the current volume of the output as voltage factor.
1.0 means 100%, 0.5 means 50% voltage/25% power, 0.0 means 0%
