The API was never really finished, or implemented, but you can get the
basic idea by looking at
(see specifically TH_ENCCTL_SETUP_VBR and TH_ENCCTL_SETUP_CQI). The idea
was that these functions could be called at any point during the
encoding process to change the current encoding mode and parameters. A
TH_ENCCTL_SETUP_ABR was planned for an average bitrate mode, exposing
things like rate-control buffer size, etc.
