      basePath - basePath for IApplicationInstance
      mediaName - media name
      mediaExtension - media extension from mediaReaders

    • open

      void open() throws IOException
      Open the media asset
      Throws:
      IOException

    • close

      void close() throws IOException
      Close the media asset
      Throws:
      IOException

    • isOpen

      boolean isOpen()
      Is the media asset open
      Returns:
      true if media asset is open

    • getFilePointer

      long getFilePointer()
      Get the current byte location in the media asset
      Returns:
      current byte location in the media asset

    • seek

      void seek(long pos)
      Seek to a position in the media asset
