Type definitions
type VulkanH264EncoderOptions = {
type:"vulkan_h264";
bitrate?:
|number
| {
average_bitrate:number;
max_bitrate:number;
};
keyframe_interval_ms?:number;
};
Properties
bitrate
Desired bitrate of the output stream, in bits per second. If only a number is specified then it defines the average_bitrate.
The max_bitrate is then set to 1.25x this value.
Type: number | { average_bitrate: number; max_bitrate: number; }
Default value: Calculated based on framerate and resolution. Eg. for 30 FPS in 1080p
the average_bitrate would be 5000 kb/s and max_bitrate 6250 kb/s.
Properties
average_bitrate
Average bitrate measured in bits per second. Encoder will try to keep the bitrate around the provided average, but may temporarily increase it to the provided max bitrate.
Type: number
max_bitrate
Max bitrate measured in bits per second.
Type: number
keyframe_interval_ms
Interval between 2 consecutive keyframes, in milliseconds.
