Returns meta data for the current media used by the media player. QMediaMetaData QMediaPlayer:: metaData() const Note: Getter function for property seekable. Most file based media files are seekable, but live streams usually are not. Returns true if the media player is supported on this platform. Note: Getter function for property error. QMediaPlayer::Error QMediaPlayer:: error() const Note: Getter function for property duration. For live streams, the duration usually changes during playback as more data becomes available. Returns 0 if the media player doesn't have a valid media file or stream. Returns the duration of the current media in ms. The returned QMediaTimeRange object describes the time ranges that are buffered and available for immediate playback. When streaming media from a remote source, different parts of the media file can be available locally. Returns a QMediaTimeRange describing the currently buffered data. QMediaTimeRange QMediaPlayer:: bufferedTimeRange() const Note: Getter function for property bufferProgress. Playback will resume once the buffer reaches 1, meaning enough data has been buffered to be able to resume playback.īufferProgress() will always return 1 for local files. Returns a number betwee 0 and 1 when buffering data.Ġ means that there is no buffered data available, playback is usually stalled in this case. float QMediaPlayer:: bufferProgress() const Note: Getter function for property audioTracks. The QMediaMetaData returned describes the properties of individual tracks.ĭifferent audio tracks can for example contain audio in different languages. Lists the set of available audio tracks inside the media. QMediaPlayer:: ~QMediaPlayer()ĭestroys the player object. Stop playing, and reset the play position to the beginning. Note: Notifier signal for property source. Signals that the media source has been changed to media. void QMediaPlayer:: sourceChanged(const QUrl & media) Listen for the mediaStatusChanged() and error() signals to be notified when the media is loaded, and if an error occurs during loading. It does not wait for the media to finish loading and does not check for errors. Note: This function returns immediately after recording the specified source of the media. Setting the media to a null QUrl will cause the player to discard all information relating to the current media source and to cease all I/O operations related to that media. void QMediaPlayer:: setSource(const QUrl & source) Note: Notifier signal for property seekable. Signals the seekable status of the player object has changed. void QMediaPlayer:: seekableChanged( bool seekable) Note: Notifier signal for property position. Signals the position of the content has changed to position, expressed in milliseconds. void QMediaPlayer:: positionChanged( qint64 position) Note: Notifier signal for property playbackRate. Signals the playbackRate has changed to rate. void QMediaPlayer:: playbackRateChanged( qreal rate) Start or resume playing the current source. Note: Notifier signal for property mediaStatus. Signals that the status of the current media has changed. void QMediaPlayer:: mediaStatusChanged( QMediaPlayer::MediaStatus status)
Note: Notifier signal for property hasVideo. Signals the availability of visual content has changed to videoAvailable. void QMediaPlayer:: hasVideoChanged( bool videoAvailable) Note: Notifier signal for property hasAudio. Signals the availability of audio content has changed to available. void QMediaPlayer:: hasAudioChanged( bool available) Signals that an error condition has occurred, with errorString containing a description of the error. void QMediaPlayer:: errorOccurred( QMediaPlayer::Error error, const QString & errorString) Note: Notifier signal for property duration. Signals the duration of the content has changed to duration, expressed in milliseconds. void QMediaPlayer:: durationChanged( qint64 duration) Note: Notifier signal for property bufferProgress. Signals the amount of the local buffer filled as a number between 0 and 1. void QMediaPlayer:: bufferProgressChanged( float filled) Member Function Documentation QMediaPlayer:: QMediaPlayer( QObject * parent = nullptr)Ĭonstructs a QMediaPlayer instance as a child of parent. The player is in the StoppedState.ĭefines the current state of a media player. Playback has reached the end of the current media. The player is in the PlayingState or PausedState. The player has fully buffered the current media.
The player is buffering data but has enough data buffered for playback to continue for the immediate future. Playback of the current media has stalled due to insufficient buffering or some other temporary interruption.
