- Method Detail
  - init
```
public void init(ExtractorOutput output)
```
    Description copied from interface: Extractor
    
    Initializes the extractor with an ExtractorOutput. Called at most once.
    
    Specified by:
    
    init in interface Extractor
    
    Parameters:
    
    output - An ExtractorOutput to receive extracted data.
  - sniff
```
public boolean sniff(ExtractorInput input)
              throws IOException
```
    Description copied from interface: Extractor
    
    Returns whether this extractor can extract samples from the ExtractorInput, which must provide data from the start of the stream.
    If true is returned, the input's reading position may have been modified. Otherwise, only its peek position may have been modified.
    
    Specified by:
    
    sniff in interface Extractor
    
    Parameters:
    
    input - The ExtractorInput from which data should be peeked/read.
    
    Returns:
    
    Whether this extractor can read the provided input.
    
    Throws:
    
    IOException - If an error occurred reading from the input.
  - read
```
public int read(ExtractorInput input,
                PositionHolder seekPosition)
         throws IOException
```
    Description copied from interface: Extractor
    
    Extracts data read from a provided ExtractorInput. Must not be called before Extractor.init(ExtractorOutput).
    A single call to this method will block until some progress has been made, but will not block for longer than this. Hence each call will consume only a small amount of input data.
    In the common case, Extractor.RESULT_CONTINUE is returned to indicate that the ExtractorInput passed to the next read is required to provide data continuing from the position in the stream reached by the returning call. If the extractor requires data to be provided from a different position, then that position is set in seekPosition and Extractor.RESULT_SEEK is returned. If the extractor reached the end of the data provided by the ExtractorInput, then Extractor.RESULT_END_OF_INPUT is returned.
    When this method throws an IOException, extraction may continue by providing an ExtractorInput with an unchanged read position to a subsequent call to this method.
    
    Specified by:
    
    read in interface Extractor
    
    Parameters:
    
    input - The ExtractorInput from which data should be read.
    
    seekPosition - If Extractor.RESULT_SEEK is returned, this holder is updated to hold the position of the required data.
    
    Returns:
    
    One of the RESULT_ values defined in this interface.
    
    Throws:
    
    IOException - If an error occurred reading from or parsing the input.
  - seek
```
public void seek(long position,
                 long timeUs)
```
    Description copied from interface: Extractor
    
    Notifies the extractor that a seek has occurred.
    Following a call to this method, the ExtractorInput passed to the next invocation of Extractor.read(ExtractorInput, PositionHolder) is required to provide data starting from position in the stream. Valid random access positions are the start of the stream and positions that can be obtained from any SeekMap passed to the ExtractorOutput.
    
    Specified by:
    
    seek in interface Extractor
    
    Parameters:
    
    position - The byte offset in the stream from which data will be provided.
    
    timeUs - The seek time in microseconds.
  - release
```
public void release()
```
    Description copied from interface: Extractor
    
    Releases all kept resources.
    
    Specified by:
    
    release in interface Extractor
