Abstract
This disclosure describes systems, methods, and devices related to generating region-based quantization parameters for video encoding. A method may include receiving, at a hardware encoder, source video comprising video frames; receiving, at the hardware encoder, from software associated with the hardware encoder, a video frame-level quantization parameter for a first video frame of the video frames; receiving, at the hardware encoder, from an application, a delta quantization parameter map, the delta quantization parameter map comprising per-pixel block quantization parameter modifications for respective pixel blocks of the first video frame; determining, by the hardware encoder, for the respective pixel blocks, respective sums of the per-pixel block quantization parameter modifications and the video frame-level quantization parameter; generating, by the hardware encoder, quantization parameters for the respective pixel blocks, the quantization parameters being the respective sums; and generating, by the hardware encoder, a bitstream based on the video frames and the quantization parameters.
