| 20 | <p>This function performs the last stage of three-step encoding setup, as described in the API overview under <a href="overview.html#BBR">managed bitrate modes</a>. |
|---|
| 21 | |
|---|
| 22 | <p>Before this function is called, the <a |
|---|
| 23 | href="vorbis_info.html">vorbis_info</a> struct should be initialized |
|---|
| 24 | by using vorbis_info_init() from the libvorbis API, one of <a |
|---|
| 25 | href="vorbis_encode_setup_managed.html">vorbis_encode_setup_managed()</a> |
|---|
| 26 | or <a |
|---|
| 27 | href="vorbis_encode_setup_vbr.html">vorbis_encode_setup_vbr()</a> |
|---|
| 28 | called to initialize the high-level encoding setup, and <a |
|---|
| 29 | href="vorbis_encode_ctl.html">vorbis_encode_ctl()</a> called if |
|---|
| 30 | necessary to make encoding setup changes. vorbis_encode_setup_init() |
|---|
| 31 | finalizes the highlevel encoding structure into a complete encoding |
|---|
| 32 | setup after which the application may make no further setup changes.<p> |
|---|
| 33 | |
|---|
| 34 | After encoding, vorbis_info_clear should be called. |
