# MediaSource Class Reference

`from PyKDE4.phonon import *`

Namespace: Phonon

## Detailed Description

\class MediaSource mediasource.h Phonon/MediaSource Note that all constructors of this class are implicit, so that you can simply write

     MediaObject m;
     QString fileName("/home/foo/bar.ogg");
     QUrl url("http://www.example.com/stream.mp3");
     QBuffer *someBuffer;
     m.setCurrentSource(fileName);
     m.setCurrentSource(url);
     m.setCurrentSource(someBuffer);
     m.setCurrentSource(Phonon.Cd);

## Method Documentation

__init__ | ( |  | self ) |

Creates an empty MediaSource.

An empty MediaSource is considered valid and can be set on a MediaObject to unload its current media.

See also:
  Empty

__init__ | ( | self, |
|  | QString | fileName
| ) |  |  |

Creates a MediaSource object for a local file or a Qt resource.

Parameters:

  | fileName | file name of a local media file or a Qt resource that was compiled in.

__init__ | ( | self, |
|  | QUrl | url
| ) |  |  |

Creates a MediaSource object for a URL.

Parameters:

  | url | URL to a media file or stream.

__init__ | ( | self, |
|  | Phonon::DiscType | discType,
|  | QString | deviceName=QString()
| ) |  |  |

Creates a MediaSource object for discs.

Parameters:

  | discType | See DiscType

Parameters:

  | deviceName | A platform dependent device name. This can be useful if the computer has more than one CD drive. It is recommended to use Solid to retrieve the device name in a portable way.

__init__ | ( | self, |
|  | Phonon.AbstractMediaStream | stream
| ) |  |  |

Creates a MediaSource object for a data stream.

Your application can provide the media data by subclassing AbstractMediaStream and passing a pointer to that object. %Phonon will never delete the stream.

Parameters:

  | stream | The AbstractMediaStream subclass to provide the media data.

See also:
  setAutoDelete

__init__ | ( | self, |
|  | QIODevice | ioDevice
| ) |  |  |

Creates a MediaSource object for a QIODevice.

This constructor can be very handy in the combination of QByteArray and QBuffer.

Parameters:

  | ioDevice | An arbitrary readable QIODevice subclass. If the device is not opened MediaSource will open it as QIODevice.ReadOnly. Sequential I/O devices are possible, too. For those MediaObject.isSeekable() will have to return false obviously.

See also:
  setAutoDelete

__init__ | ( | self, |
|  | Phonon.MediaSource | rhs
| ) |  |  |

Constructs a copy of rhs.

This constructor is fast thanks to explicit sharing.

bool autoDelete | ( |  | self ) |

Returns the setting of the auto-delete option. The default is false.

See also:
  setAutoDelete

QString deviceName | ( |  | self ) |

Returns the device name of the MediaSource if type() == Disc; otherwise returns QString().

Phonon::DiscType discType | ( |  | self ) |

Returns the disc type of the MediaSource if type() == Disc; otherwise returns NoDisc.

QString fileName | ( |  | self ) |

Returns the file name of the MediaSource if type() == LocalFile; otherwise returns QString().

bool operator == | ( | self, |
|  | Phonon.MediaSource | rhs
| ) |  |  |

Returns true if this MediaSource is equal to rhs; otherwise returns false.

setAutoDelete | ( | self, |
|  | bool | enable
| ) |  |  |

Tell the MediaSource to take ownership of the AbstractMediaStream or QIODevice that was passed in the constructor.

The default setting is false, for safety. If you turn it on, you should only access the AbstractMediaStream/QIODevice object as long as you yourself keep a MediaSource object around. As long as you keep the MediaSource object wrapping the stream/device the object will not get deleted.

See also:
  autoDelete

Phonon.AbstractMediaStream stream | ( |  | self ) |

Returns the media stream of the MediaSource if type() == Stream; otherwise returns 0. QIODevices are handled as streams, too.

Phonon.MediaSource.Type type | ( |  | self ) |

Returns the type of the MediaSource (depends on the constructor that was used).

See also:
  Type

QUrl url | ( |  | self ) |

Returns the url of the MediaSource if type() == URL or type() == LocalFile; otherwise returns QUrl().
