Constant libaom_sys::AOME_SET_MAX_INTRA_BITRATE_PCT

pub const AOME_SET_MAX_INTRA_BITRATE_PCT: aome_enc_control_id = 26;

Codec control function to set max data rate for intra frames, unsigned int parameter

This value controls additional clamping on the maximum size of a keyframe. It is expressed as a percentage of the average per-frame bitrate, with the special (and default) value 0 meaning unlimited, or no additional clamping beyond the codec’s built-in algorithm.

For example, to allocate no more than 4.5 frames worth of bitrate to a keyframe, set this to 450.
