vorbis_analysis

+ +

declared in "vorbis/codec.h";

+ +

Once the uncompressed audio data has been divided into blocks, this +function is called on each block. It looks up the encoding mode and +dispatches the block to the forward transform provided by that mode. +

+

When using a basic encoding mode, with no bitrate management, +an ogg_packet pointer can be given, and the coded block is returned +directly through that structure and can be placed in the output stream. +

+

Otherwise, NULL should be passed for the ogg_packet pointer. In +that case, after the transform has been applied, the block must passed +to vorbis_bitrate_addblock() for further coding. This method works with +both basic and managed encoding modes, so it's recommended for new code. +

+ + + + + +
+

+extern int      vorbis_analysis(vorbis_block *vb,ogg_packet *op);
+
+
+ +

Parameters

+
+
vb
+
Pointer to the vorbis_block to be encoded.
+
op
+
Optional pointer to an ogg_packet. This is normally NULL, +and the final output is obtained by passing vb though the +vorbis_bitrate_*() interface to perform further refinement. +However, when not using a bitrate managed encoding mode, it +is possible to skip that step by providing an ogg_packet pointer +here, obtaining the compressed data directly.
