bitrate_hard_min
|
|
Packit |
06404a |
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.
|
|
Packit |
06404a |
bitrate_hard_max
|
|
Packit |
06404a |
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.
|
|
Packit |
06404a |
bitrate_hard_window
|
|
Packit |
06404a |
the window period (in seconds) used to regulate the hard bitrate minimum and maximum
|

Packit |
06404a |
|
|
Packit |
06404a |
bitrate_av_lo
|
|
Packit |
06404a |
soft lower limit (in kilobits per second) below which the average bitrate tracker will start nudging the bitrate higher.
|
|
Packit |
06404a |
bitrate_av_hi
|
|
Packit |
06404a |
soft upper limit (in kilobits per second) above which the average bitrate tracker will start nudging the bitrate lower.
|
|
Packit |
06404a |
bitrate_av_window
|
|
Packit |
06404a |
the window period (in seconds) used to regulate the average bitrate minimum and maximum.
|
|
Packit |
06404a |
bitrate_av_window_center
|
|
Packit |
06404a |
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.
