Text { text: "Click Me!"; font.pointSize: 24; width: 150; height: 50; MediaPlayer { id: playMusic source: "music.wav" audioOutput: AudioOutput {} } MouseArea { anchors.fill: parent onPressed: { playMusic.play() } } }
You can use MediaPlayer together with a MultiMedia::AudioOutput to play audio content, or you can use it in conjunction with a Multimedia::VideoOutput for rendering video.
Item { MediaPlayer { id: mediaplayer source: "groovy_video.mp4" audioOutput: AudioOutput {} videoOutput: videoOutput } VideoOutput { id: videoOutput anchors.fill: parent } MouseArea { anchors.fill: parent onPressed: mediaplayer.play(); } }

activeAudioTrack : int
This property holds the track number of the currently active audio track. Set to -1
to disable audio track.
The default property value is 0
: the first audio track.
activeSubtitleTrack : int
This property holds the track number of the currently active subtitle track. Set to -1
to disable subtitle track.
The default property value is -1
: no subtitles active.
activeVideoTrack : int
This property holds the track number of the currently active video audio track. Set to -1
to disable video track.
The default property value is 0

audioOutput : AudioOutput
This property holds the target audio output. Accepts one AudioOutput elements.
See also QMediaPlayer::setAudioOutput().
audioTracks : list<mediaMetaData>
This property holds a list of metadata. Each index refers to an audio track.
The metadata holds properties describing the individual tracks. For audio tracks the Language is usually the most important property.
See also mediaMetaData.
bufferProgress : real
This property holds how much of the data buffer is currently filled, from 0.0
(empty) to 1.0
(full).
Playback can start or resume only when the buffer is entirely filled. When the buffer is filled, MediaPlayer.Buffered
is true. When buffer progress is between 0.0
and 0.1
, MediaPlayer.Buffering
is set to true
.
A value lower than 1.0
implies that the property MediaPlayer.StalledMedia
is true
.
See also mediaStatus.
duration : int
This property holds the duration of the media in milliseconds.
If the media doesn't have a fixed duration (a live stream for example) this will be set to 0
.
error : enumeration
This property holds the error state of the audio. It can be one of the following.
Value | Description |
---|---|
NoError | There is no current error. |
ResourceError | The audio cannot be played due to a problem allocating resources. |
FormatError | The audio format is not supported. |
NetworkError | The audio cannot be played due to network issues. |
AccessDeniedError | The audio cannot be played due to insufficient permissions. |

This property holds a string describing the current error condition in more detail.
hasAudio : bool
This property holds whether the media contains audio.
hasVideo : bool

BufferedMedia | The media has buffered data. |
EndOfMedia | The media has played to the end. |
InvalidMedia | The media cannot be played. |
metaData : mediaMetaData
Returns meta data for the current media used by the media player.
Meta data can contain information such as the title of the video or its creation date.

playbackRate : real
This property holds the rate at which audio is played at as a multiple of the normal rate.

This property holds whether the position of the media can be changed.
source : url
This property holds the source URL of the media.
