| 20 <p>This fuction examines the available uncompressed data and tries to | |
| 21 break it into appropriate sized blocks. It should be called in a loop | |
| 22 after adding new data with vorbis_analysis_buffer()/vorbis_analysis_wrote() | |
| 23 until it returns zero (need more data) or an negative value (error). | |
| 24 </p> | |
| 25 <p> | |
| 26 Each block returned should be passed to vorbis_analysis() for transform | |
| 27 and coding. | |
