An example apparatus for adaptively encoding video frames includes a network analyzer to predict an instant bitrate based on channel throughput feedback received from a network. The apparatus also includes a content analyzer to generate ladder info based on a received frame. The apparatus further includes an adaptive decision executer to determine a frame rate, a video resolution, and a target frame size based on the predicted instant bitrate and the ladder outputs. The apparatus further includes an encoder to encode the frame based on the frame rate, the video resolution, and the target frame size.

An apparatus and a method filters reconstructed images, in particular, video images, with adaptive multiplicative filters. The apparatus and method groups the multiplier coefficients of the filter into at least two groups; determines the value of each multiplier coefficient in a first group so as to be allowed to assume any value in a first set of allowed values of multiplier coefficients, determines the value of each multiplier coefficient in a second group so as to be allowed to assume any value in a second set of allowed values of multiplier coefficients, and filters the set of samples of an image with the filter. At least one of the first and second sets has at least one value that is not in the other set.

The present disclosure relates to an image processing device and method for enabling suppression of an increase in encoding load.

An encoding mode of encoding of an image is set by setting a transform type with a minimum encoding cost in a non-joint chrominance encoding mode as a transform type in a joint chrominance encoding mode, and deriving an encoding cost in the joint chrominance encoding mode. The present disclosure can be applied to, for example, an image processing device, an image encoding device, an information processing device, an electronic device, an image processing method, an information processing method, or the like.

A video encoding/decoding method and apparatus, a computer device, and a storage medium. The method comprises: for each non-key frame in a video frame sequence, dividing a current non-key frame into a plurality of sub-image blocks according to information of an object in the current non-key image, and determining an importance level of each sub-image block; according to a pre-stored first correlation between different importance levels and different resolutions, performing conversion to make each sub-image block in each non-key frame have a resolution corresponding to the importance level of the sub-image block, wherein in the first correlation, a higher importance level corresponds to a higher resolution, and the highest importance level corresponds to a target highest resolution; and performing video encoding on the video frame sequence to obtain encoded video data. By means of the method, memory and bandwidth occupied by a video can be reduced.

Described herein are video streaming techniques for applications and workloads executed in the cloud. In one example, the cloud server device encodes display frames using low-delay encoding techniques for transmission to a client device. The cloud server device receives an overlay bitstream from a client device, combines the overlay data with the display frames, and encodes the frames for the viewers using statistics from the display frames encoded for the client device and/or from the overlay data. The cloud server device can then transmit the bitstream to a third device for viewing (e.g., to a viewer device or a streaming server device).
