Modifier and Type | Method and Description |
---|---|
protected javax.media.control.FrameRateControl |
createFrameRateControl()
Overrides
AbstractVideoPushBufferCaptureDevice.createFrameRateControl() to
provide a FrameRateControl which gets and sets the frame rate of
the QTCaptureDecompressedVideoOutput represented by the
QuickTimeStream made available by this DataSource. |
protected QuickTimeStream |
createStream(int streamIndex,
javax.media.control.FormatControl formatControl)
Creates a new PushBufferStream which is to be at a specific
zero-based index in the list of streams of this
PushBufferDataSource.
|
protected void |
doConnect()
Opens a connection to the media source specified by the
MediaLocator of this DataSource.
|
protected void |
doDisconnect()
Closes the connection to the media source specified by the
MediaLocator of this DataSource.
|
protected void |
doStart()
Starts the transfer of media data from this DataSource.
|
protected void |
doStop()
Stops the transfer of media data from this DataSource.
|
protected javax.media.Format[] |
getSupportedFormats(int streamIndex)
Gets the Formats which are to be reported by a
FormatControl as supported formats for a
PushBufferStream at a specific zero-based index in the list of
streams of this PushBufferDataSource.
|
protected javax.media.Format |
setFormat(int streamIndex,
javax.media.Format oldValue,
javax.media.Format newValue)
Attempts to set the Format to be reported by the
FormatControl of a PushBufferStream at a specific
zero-based index in the list of streams of this
PushBufferDataSource.
|
void |
setLocator(javax.media.MediaLocator locator)
