QP range specification for external video rate control
Abstract:
Operations of a method include obtaining a segment of image data that represents a portion of a frame of video image data to be encoded. The operations include determining, based on the segment and a target bitrate, a quantization parameter (QP) value for the segment. The operations include determining a minimum QP value and a maximum QP value that establishes a range of QP values an integrated bit rate control algorithm may use to encode the segment. The operations include encoding the segment with a first QP value that is greater than the minimum QP value and less than the maximum QP value. The operations include adjusting, by the bit rate control algorithm, the first QP value to a second QP value that is greater than the minimum QP value and less than the maximum QP value. The operations include transmitting the encoded segment to a remote device.
