Abstract: This disclosure describes systems, methods, and devices related to generating visual quality metrics for encoded video frames. A method may include generating respective first visual quality metrics for pixels of an encoded video frame; generating respective second visual quality metrics for the pixels, the respective first visual quality metrics and the respective second visual quality metrics indicative of estimated human perceptions of the encoded video frame; generating a pixel block-based weight for the respective first visual quality metrics; generating a frame-based weight for the respective second visual quality metrics; and generating, based on the respective first visual quality metrics, the pixel block-based weight, the respective second visual quality metrics, and the frame-based weight, a human visual score indicative of a visual quality of the encoded video frame.

Abstract: Example systems, apparatus, articles of manufacture, and methods to implement hardware-accelerated intra frame encoding are disclosed. Example hardware-accelerated intra frame video encoders disclosed herein are VC3 compliant. Some example video encoders disclosed herein quantize alternating current (AC) coefficients of a macroblock of an input image frame using a small set of anchor quantization scale factors (QSFs), and interpolate between the resulting bit counts for the first anchor QSFs to determine an estimated QSF meets a target bit budget. Some example video encoders disclosed herein perform bit coding with a round-robin packing strategy that distributes the packing of encoded symbols among macroblocks and discards excess symbols to avoid exceeding the specified frame size. Some example video encoders disclosed herein are configurable via control circuitry and/or a driver that selects target bit budgets, anchor QSFs, encoding modes, etc.

Abstract: This disclosure describes a validation framework for media encode systems. An example method may include generating, by a system associated with a video encoder simulation model, a first set of video encoding parameters. The example method may also include generating, by the system associated with the video encoder simulation model, a second set of video encoding parameters. The example method may also include sending the second set of video encoding parameters to an encoder device. The example method may also include receiving, by a second device, the first output. The example method may also include receiving, by the second device, a second output, wherein the second output represents second encoded video content generated by the encoder device based on the second set of video encoding parameters. The example method may also include performing a validation of the encoder device by comparing the first output and the second output.
