One of the target applications of VCA is content-adaptive encoding where the raw video frames (yuv or y4m) are input to VCA, which analyzes the spatial and temporal characteristics of the video. This analysis is transferred to the encoder via Application Programming Interface (API) to aid the encoding process. Since the analysis provided by VCA is codec-agnostic, encoder implementations of any codec may use the analysis data collected at the rate of 370fps (for 2160p)!
