| class | StreamInterface |
| enum Type |
Identifies the type of media described by the MediaSource object.
| Enumerator | |
|---|---|
| Invalid |
The MediaSource object does not describe any valid source. |
| LocalFile |
The MediaSource object describes a local file. |
| Url |
The MediaSource object describes a URL, which can be both a local file and a file on the network. |
| Disc |
The MediaSource object describes a disc. |
| Stream |
The MediaSource object describes a data stream. This is also the type used for QIODevices.
|
| Empty |
An empty MediaSource. It can be used to unload the current media from a MediaObject.
|
Definition at line 70 of file mediasource.h.
| MediaSource | ( | ) |
Creates an empty MediaSource.
An empty MediaSource is considered valid and can be set on a MediaObject to unload its current media.
| MediaSource | ( | const QString & | fileName | ) |
Creates a MediaSource object for a local file or a Qt resource.
| fileName | file name of a local media file or a Qt resource that was compiled in. |
| MediaSource | ( | const QUrl & | url | ) |
Creates a MediaSource object for a URL.
| url | URL to a media file or stream. |
| MediaSource | ( | Phonon::DiscType | discType, |
| const QString & | deviceName = QString() |
||
| ) |
Creates a MediaSource object for discs.
| discType | See DiscType |
| 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. |
| MediaSource | ( | 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.
| stream | The AbstractMediaStream subclass to provide the media data. |
| MediaSource | ( | QIODevice * | ioDevice | ) |
Creates a MediaSource object for a QIODevice.
This constructor can be very handy in the combination of QByteArray and QBuffer.
| 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. |
| ~MediaSource | ( | ) |
Creates a MediaSource object for capture devices.
Destroys the MediaSource object.
| MediaSource | ( | const MediaSource & | rhs | ) |
Constructs a copy of rhs.
This constructor is fast thanks to explicit sharing.
|
protected |
| MediaSource& operator= | ( | const MediaSource & | rhs | ) |
Assigns rhs to this MediaSource and returns a reference to this MediaSource.
This operation is fast thanks to explicit sharing.
| bool operator== | ( | const MediaSource & | rhs | ) | const |
Returns true if this MediaSource is equal to rhs; otherwise returns false.
| void setAutoDelete | ( | 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.
| bool autoDelete | ( | ) | const |
Returns the type of the MediaSource (depends on the constructor that was used).
| QString fileName | ( | ) | const |
Returns the file name of the MediaSource if type() == LocalFile; otherwise returns QString().
| QUrl url | ( | ) | const |
Returns the url of the MediaSource if type() == URL or type() == LocalFile; otherwise returns QUrl().
| Phonon::DiscType discType | ( | ) | const |
Returns the disc type of the MediaSource if type() == Disc; otherwise returns NoDisc.
| QString deviceName | ( | ) | const |
Returns the device name of the MediaSource if type() == Disc; otherwise returns QString().
| AbstractMediaStream* stream | ( | ) | const |
Returns the media stream of the MediaSource if type() == Stream; otherwise returns 0.
QIODevices are handled as streams, too.
