Libvorbisenc Setup Examples

- -VBR is always the recommended mode for Vorbis encoding when -there's no need to impose bitrate constraints. True VBR encoding will -always produce the most consistent quality output as well as the -highest quality for a the bits used. - -

The following code examples prepare a -vorbis_info structure for encoding -use with libvorbis.

- -

Example: encoding using a VBR quality mode

- - -

 
-   vorbis_info_init(&vi);
-
-  /*********************************************************************
-   Encoding using a VBR quality mode.  The usable range is -.1
-   (lowest quality, smallest file) to 1.0 (highest quality, largest file).
-   Example quality mode .4: 44kHz stereo coupled, roughly 128kbps VBR 
-   *********************************************************************/
-  
-   ret = vorbis_encode_init_vbr(&vi,2,44100,.4);
-
-  /*********************************************************************
-   do not continue if setup failed; this can happen if we ask for a
-   mode that libVorbis does not support (eg, too low a quality mode, etc,
-   will return 'OV_EIMPL')
-   *********************************************************************/
-
-   if(ret) exit(1);
-

- -

Example: encoding using average bitrate (ABR)

- - -

 
-   vorbis_info_init(&vi);
-
-  /*********************************************************************
-   Encoding using an average bitrate mode (ABR).
-   example: 44kHz stereo coupled, average 128kbps ABR 
-   *********************************************************************/
-  
-   ret = vorbis_encode_init(&vi,2,44100,-1,128000,-1);
-
-  /*********************************************************************
-   do not continue if setup failed; this can happen if we ask for a
-   mode that libVorbis does not support (eg, too low a bitrate, etc,
-   will return 'OV_EIMPL')
-   *********************************************************************/
-
-   if(ret) exit(1);
-

- -

Example: encoding using constant bitrate (CBR)

- - -

 
-   vorbis_info_init(&vi);
-
-  /*********************************************************************
-   Encoding using a constant bitrate mode (CBR).
-   example: 44kHz stereo coupled, average 128kbps CBR 
-   *********************************************************************/
-  
-   ret = vorbis_encode_init(&vi,2,44100,128000,128000,128000);
-
-  /*********************************************************************
-   do not continue if setup failed; this can happen if we ask for a
-   mode that libVorbis does not support (eg, too low a bitrate, etc,
-   will return 'OV_EIMPL')
-   *********************************************************************/
-
-   if(ret) exit(1);
-

- -

Example: encoding using VBR selected by approximate bitrate

- - -

 
-   vorbis_info_init(&vi);
-
-  /*********************************************************************
-   Encode using a quality mode, but select that quality mode by asking for
-   an approximate bitrate.  This is not ABR, it is true VBR, but selected
-   using the bitrate interface, and then turning bitrate management off:
-   *********************************************************************/
-
-   ret = ( vorbis_encode_setup_managed(&vi,2,44100,-1,128000,-1) ||
-           vorbis_encode_ctl(&vi,OV_ECTL_RATEMANAGE2_SET,NULL) ||
-           vorbis_encode_setup_init(&vi));
-
-  /*********************************************************************
-   do not continue if setup failed; this can happen if we ask for a
-   mode that libVorbis does not support (eg, too low a bitrate, etc,
-   will return 'OV_EIMPL')
-   *********************************************************************/
-
-   if(ret) exit(1);
