ovectl_ratemanage_arg

+ +

declared in "vorbis/vorbisenc.h"

+ +

+ +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. Note that this is +a deprecated interface; 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. + +

+ + + + + +

Relevant Struct Members

+
+ +
management_active
+
nonzero if bitrate management is active
+ +
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.
+
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.
+
bitrate_hard_window
+
the window period (in seconds) used to regulate the hard bitrate minimum and maximum
+ +
bitrate_av_lo
+
soft lower limit (in kilobits per second) below which the average bitrate tracker will start nudging the bitrate higher.
+
bitrate_av_hi
+
soft upper limit (in kilobits per second) above which the average bitrate tracker will start nudging the bitrate lower.
+
bitrate_av_window
+
the window period (in seconds) used to regulate the average bitrate minimum and maximum.
+
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.
