Abstract: A video encoder with quality estimation is shown. The video encoder has a video compressor, a video reconstructor, a quality estimator, and an encoder top controller. The video compressor receives the source data of a video to generate compressed data. The video reconstructor is coupled to the video compressor for generation of playback-level data that is buffered for inter prediction by the video compressor, wherein the video reconstructor generates intermediate data and, based on the intermediate data, the video reconstructor generates playback-level data. The quality estimator is coupled to the video reconstructor to receive the intermediate data. Quality estimation is performed based on the intermediate data rather than the playback-level data. Based on the quality estimation result, the encoder top controller adjusts at least one video compression factor in real time.
