Constructor Detail

• FlacStreamMetadata

  public FlacStreamMetadata​(byte[] data,
                            int offset)

  Parses binary FLAC stream info metadata.

  Parameters:

  data - An array containing binary FLAC stream info block.

  offset - The offset of the stream info block in data, excluding the header (i.e. the offset points to the first byte of the minimum block size).

  public FlacStreamMetadata​(int minBlockSizeSamples,
                            int maxBlockSizeSamples,

Method Detail

• getMaxDecodedFrameSize

  public int getMaxDecodedFrameSize()

  Returns the maximum size for a decoded frame from the FLAC stream.

• getDecodedBitrate

  public int getDecodedBitrate()

  Returns the bitrate of the stream after it's decoded into PCM.

• getDurationUs

  public long getDurationUs()

  Returns the duration of the FLAC stream in microseconds, or C.TIME_UNSET if the total number of samples if unknown.

• getSampleNumber

  public long getSampleNumber​(long timeUs)

  Returns the sample number of the sample at a given time.

  Parameters:

  timeUs - Time position in microseconds in the FLAC stream.

  Returns:

  The sample number corresponding to the time position.

• getApproxBytesPerFrame

  public long getApproxBytesPerFrame()

  Returns the approximate number of bytes per frame for the current FLAC stream.

• getFormat

  public Format getFormat​(byte[] streamMarkerAndInfoBlock,

                          Metadata id3Metadata)

  Returns a Format extracted from the FLAC stream metadata.

  streamMarkerAndInfoBlock is updated to set the bit corresponding to the stream info last metadata block flag to true.

  Parameters:

  streamMarkerAndInfoBlock - An array containing the FLAC stream marker followed by the stream info block.
