libvorbisenc documentation
Packit 06404a 
libvorbisenc version 1.3.2 - 20101101
Packit 06404a
Packit 06404a
Packit 06404a
Packit 06404a 
Libvorbisenc API changes 1.0  through 1.1
Packit 06404a
Packit 06404a 
This document describes API additions to libvorbisenc between release
Packit 06404a 
1.0 and 1.1.
Packit 06404a
Packit 06404a 
1.0.1
Packit 06404a
Packit 06404a 
The programming API and binary application ABI are unchanged and fully
Packit 06404a 
forward/backward compatible between release 1.0 and 1.0.1.  Libvorbis,
Packit 06404a 
libvorbisenc and libvorbisfile must match versions amongst themselves,
Packit 06404a 
however.
Packit 06404a
Packit 06404a 
1.1
Packit 06404a
Packit 06404a 
The binary ABI from release 1.0.1 to 1.1 is backward compatible;
Packit 06404a 
applications linked against libvorbis/libvorbisenc 1.0 and 1.0.1 will
Packit 06404a 
continue to function correctly when upgrading the libvorbis and
Packit 06404a 
libvorbisenc dynamic libraries without re-linking.
Packit 06404a
Packit 06404a 
Release 1.1 adds several possible requests to the libvorbisenc
Packit 06404a 
href="vorbis_encode_ctl.html">vorbis_encode_ctl() call in order to
Packit 06404a 
reflect the shift to bit-reservoir style
Packit 06404a 
bitrate management. In addition, several
Packit 06404a 
href="vorbis_encode_ctl.html">vorbis_encode_ctl() requests are
Packit 06404a 
deprecated (but functional) as they are redered semantically obsolete
Packit 06404a 
by the new bitrate management.
Packit 06404a
Packit 06404a 
Deprecated in 1.1
Packit 06404a
Packit 06404a 
These calls are still available to older codebases to preserve
Packit 06404a 
compatability; the fields of the
Packit 06404a 
href="ovectl_ratemanage_arg.html">ovectl_ratemanage_arg argument
Packit 06404a 
are mapped as closely as possible to the fields of the new
Packit 06404a 
href="ovectl_ratemanage2_arg.html">ovectl_ratemanage2_arg
Packit 06404a 
structure.
Packit 06404a
Packit 06404a
Packit 06404a 
OV_ECTL_RATEMANAGE_GET:
 Use
Packit 06404a 
href="vorbis_encode_ctl.html#OV_ECTL_RATEMANAGE2_GET">OV_ECTL_RATEMANAGE2_GET
Packit 06404a 
instead.
Packit 06404a
Packit 06404a
Packit 06404a 
OV_ECTL_RATEMANAGE_SET:
 Use
Packit 06404a 
href="vorbis_encode_ctl.html#OV_ECTL_RATEMANAGE2_SET">OV_ECTL_RATEMANAGE2_SET
Packit 06404a 
instead.
Packit 06404a
Packit 06404a 
OV_ECTL_RATEMANAGE_AVG:
 Use
Packit 06404a 
href="vorbis_encode_ctl.html#OV_ECTL_RATEMANAGE2_SET">OV_ECTL_RATEMANAGE2_SET
Packit 06404a 
instead.
Packit 06404a
Packit 06404a 
OV_ECTL_RATEMANAGE_HARD:
 Use
Packit 06404a 
href="vorbis_encode_ctl.html#OV_ECTL_RATEMANAGE2_SET">OV_ECTL_RATEMANAGE2_SET
Packit 06404a 
instead.
Packit 06404a
Packit 06404a
Packit 06404a 
Newly added in 1.1
Packit 06404a
Packit 06404a 
The following calls are added in 1.1 to semantically reflect movement
Packit 06404a 
to a bit-reservoir-based bitrate
Packit 06404a 
management scheme by introducing the
Packit 06404a 
href="ovectl_ratemanage2_arg.html">ovectl_ratemanage2_arg
Packit 06404a 
structure in order to better represent the abilities of the bitrate
Packit 06404a 
manager.
Packit 06404a
Packit 06404a
Packit 06404a 
OV_ECTL_RATEMANAGE2_GET
Packit 06404a
Packit 06404a 
Used to query the current state of bitrate management setup.
Packit 06404a
Packit 06404a 
OV_ECTL_RATEMANAGE2_SET
Packit 06404a
Packit 06404a 
Used to set or alter bitrate management settings.
