All Implemented Interfaces:

public class OggOpusReader extends LittleEndianInputStream
Pulls Opus packets out of an Ogg stream. Page boundaries and packet boundaries are unrelated: a packet is a run of segments ending at the first one shorter than 255, and it may cross pages.

    • mark

      public void mark(int limit)
      Overrides:

      The last page a packet ended on keeps only what its granule position gained over the one before it.
