- Method Detail
  - getTimecode
```
int getTimecode()
```
    Returns:
    
    The timecode of this block relative to its cluster
  - getTrackNumber
```
int getTrackNumber()
```
    Returns:
    
    The track number which this block is for
  - isKeyFrame
```
boolean isKeyFrame()
```
    Returns:
    
    Whether this block is a keyframe
  - getFrameCount
```
int getFrameCount()
```
    Returns:
    
    The number of frames in this block
  - getNextFrameBuffer
```
java.nio.ByteBuffer getNextFrameBuffer(MatroskaFileReader reader,
                                       int index)
                                throws java.io.IOException
```
    The reader must already be positioned at the frame that is to be read next.
    
    Parameters:
    
    reader - The reader to use to read the block contents into a buffer.
    
    index - The index of the frame to get the buffer for.
    
    Returns:
    
    A buffer where the range between position and limit contains the data for the specific frame. The contents of this buffer are only valid until the next call to this method.
    
    Throws:
    
    java.io.IOException - On read error.
