<p><i>declared in "vorbis/codec.h";</i></p>
|

|
|
|

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