AbstractQuickTimeStream (MonteCC repack 1.0.1 API)

java.lang.Object
- org.monte.media.quicktime.AbstractQuickTimeStream

Direct Known Subclasses:

QuickTimeInputStream, QuickTimeOutputStream
```
public class AbstractQuickTimeStream
extends Object
```
This is the base class for low-level QuickTime stream IO.
FIXME - Separation between AbstractQuickTimeStream and QuickTimeOutputStream is not clean. Move write methods in the track classes down to QuickTimeOutputStream.

- Field Detail
  - out
```
protected ImageOutputStream out
```
    Underlying output stream.
  - streamOffset
```
protected long streamOffset
```
    The offset in the underlying ImageOutputStream. Normally this is 0 unless the underlying stream already contained data when it was passed to the constructor.
  - mdatAtom
```
protected AbstractQuickTimeStream.WideDataAtom mdatAtom
```
    This atom holds the media data.
  - mdatOffset
```
protected long mdatOffset
```
    Offset for the mdat atom.
  - moovAtom
```
protected AbstractQuickTimeStream.CompositeAtom moovAtom
```

  - creationTime
```
protected Date creationTime
```

  - modificationTime
```
protected Date modificationTime
```
    Modification time of the movie.
  - movieTimeScale
```
protected long movieTimeScale
```

  - preferredRate
```
protected double preferredRate
```
    The preferred rate at which to play this movie. A value of 1.0 indicates normal rate.
  - preferredVolume
```

  - getRelativeStreamPosition
```
protected long getRelativeStreamPosition()
                                  throws IOException
```
    Gets the position relative to the beginning of the QuickTime stream.
    Usually this value is equal to the stream position of the underlying ImageOutputStream, but can be larger if the underlying stream already contained data.
    
    Returns:
    The relative stream position.
    
    Throws:
    
    IOException
  - seekRelative
```
protected void seekRelative(long newPosition)
                     throws IOException
```
    Seeks relative to the beginning of the QuickTime stream.
    Usually this equal to seeking in the underlying ImageOutputStream, but can be different if the underlying stream already contained data.
    
    Throws:
    
    IOException
  - typeToInt
```
protected static int typeToInt(String str)
```
  - intToType
```
protected static String intToType(int id)
```
