| 20 <p>This function creates and returns the three header packets needed | |
| 21 to configure a decoder to accept compressed data. I should be called | |
| 22 after all encoder initialization and configuration is complete. The | |
| 23 output packets should be placed in order at the start of the compressed | |
| 24 vorbis stream, prior to the first data packet. | |
