Data Fields | |
int | management_active |
nonzero if bitrate management is active More... | |
long | bitrate_hard_min |
hard lower limit (in kilobits per second) below which the stream bitrate will never be allowed for any given bitrate_hard_window seconds of time. More... | |
long | bitrate_hard_max |
hard upper limit (in kilobits per second) above which the stream bitrate will never be allowed for any given bitrate_hard_window seconds of time. More... | |
double | bitrate_hard_window |
the window period (in seconds) used to regulate the hard bitrate minimum and maximum More... | |
long | bitrate_av_lo |
soft lower limit (in kilobits per second) below which the average bitrate tracker will start nudging the bitrate higher. More... | |
long | bitrate_av_hi |
soft upper limit (in kilobits per second) above which the average bitrate tracker will start nudging the bitrate lower. More... | |
double | bitrate_av_window |
the window period (in seconds) used to regulate the average bitrate minimum and maximum. More... | |
double | bitrate_av_window_center |
Regulates the relative centering of the average and hard windows; in libvorbis 1.0 and 1.0.1, the hard window regulation overlapped but followed the average window regulation. More... | |
Please use vorbis_encode_ctl() with the ovectl_ratemanage2_arg struct and OV_ECTL_RATEMANAGE2_GET and OV_ECTL_RATEMANAGE2_SET calls in new code.
The ovectl_ratemanage_arg structure is used with vorbis_encode_ctl() and the OV_ECTL_RATEMANAGE_GET, OV_ECTL_RATEMANAGE_SET, OV_ECTL_RATEMANAGE_AVG, OV_ECTL_RATEMANAGE_HARD calls in order to query and modify specifics of the encoder's bitrate management configuration.
long ovectl_ratemanage_arg::bitrate_av_hi |
soft upper limit (in kilobits per second) above which the average bitrate tracker will start nudging the bitrate lower.
long ovectl_ratemanage_arg::bitrate_av_lo |
soft lower limit (in kilobits per second) below which the average bitrate tracker will start nudging the bitrate higher.
double ovectl_ratemanage_arg::bitrate_av_window |
the window period (in seconds) used to regulate the average bitrate minimum and maximum.
double ovectl_ratemanage_arg::bitrate_av_window_center |
Regulates the relative centering of the average and hard windows; in libvorbis 1.0 and 1.0.1, the hard window regulation overlapped but followed the average window regulation.
In libvorbis 1.1 a bit-reservoir interface replaces the old windowing interface; the older windowing interface is simulated and this field has no effect.
long ovectl_ratemanage_arg::bitrate_hard_max |
hard upper limit (in kilobits per second) above which the stream bitrate will never be allowed for any given bitrate_hard_window seconds of time.
long ovectl_ratemanage_arg::bitrate_hard_min |
hard lower limit (in kilobits per second) below which the stream bitrate will never be allowed for any given bitrate_hard_window seconds of time.
double ovectl_ratemanage_arg::bitrate_hard_window |
the window period (in seconds) used to regulate the hard bitrate minimum and maximum
int ovectl_ratemanage_arg::management_active |
nonzero if bitrate management is active
