Initial bitrate in bit/s.

sample-point:

type: int

description: |
|
|
Initial sample point in per mille (e.g. 875 equals 87.5%).

If this is unset (or if it is set to 0), the initial sample point will default to 75.0% for
|
|
bitrates over 800 kbit/s, 80.0% for bitrates over 500 kbit/s, and 87.5% for all other
|
|
bitrates.
