Abstract
Systems and methods disclosed herein may include or use a video encoder and an inference sub-system. The inference sub-system may infer a quantization matrix (QM) level from video or frame statistics within features of a media stream. The video encoder may use the QM level to apply a QM for the video encoder. The QM may be used in the video encoder for encoding the media stream.
Claims20
An encoding system comprising a video encoder and an inference sub-system, the inference sub-system to infer a quantization matrix (QM) level from video or frame statistics within features of a media stream, and the video encoder to use the QM level to apply a QM from the video encoder for encoding the media stream.
One or more circuits configured to infer a quantization matrix (QM) level from video or frame statistics within features of a media stream and configured to use the QM level to apply a QM, from different video encoding modes, for encoding the media stream.
One or more circuits configured to infer a quantization matrix (QM) level from video or frame statistics within features of a media stream, wherein the QM level is available to a video encoder to apply a QM, from different video encoding modes in the video encoder, for encoding the media stream.
A method for video encoding, the method comprising:
- receiving a media stream in a video encoder and an inference sub-system;
- inferring, using the inference sub-system, a quantization matrix (QM) level from video or frame statistics within features of a media stream;
- and
- using the QM level in the video encoder to apply a QM for encoding the media stream.
