摘要： A computer-implemented method includes receiving a feedback message from a receiver of image data. The feedback message includes a reference frame identifier associated with a reference frame correctly received or decoded by the receiver. The method further includes determining a difference between the reference frame identifier and a current frame identifier. The current frame identifier is associated with a current frame to be encoded and the difference indicates a number of frames between the reference frame and the current frame. The method also includes encoding the current frame based at least in part on the difference.

摘要： A method for controlling video coding including obtaining an image frame. The image frame includes a plurality of coding block groups each associated with a respective coding control model. The method further includes determining whether a coding block group is an initial coding block group or a subsequent coding block group of the image frame. If the coding block group is the initial coding block group, for an initial coding control model associated with the initial coding block group, values of one or more coding parameters are determined based on a bit allocation for the initial coding block group, and the initial coding block group is encoded using the initial coding control model with the determined values of the one or more coding parameters. If the coding block group is the subsequent coding block group, a bit allocation for the subsequent coding block group is updated based on the encoded initial coding block group.

摘要： A method for controlling video coding includes: obtaining an image frame from a video stream, wherein the image frame is associated with a coding control model; encoding the image frame using a quantization parameter (QP) calculated based on the coding control mode; determining whether a scene has changed significantly based on an analysis of the encoded image frame; in response to the scene having changed significantly, initializing parameters for the coding control model; and in response to no significant scene change, updating the parameters for the coding control model.

摘要： A method for controlling video coding includes obtaining a target rate for an image data unit to be encoded using one or more coding parameters. The one or more coding parameters are determined based on the target rate and a rate control model associated with one or more model parameters. The method further includes determining the one or more model parameters associated with the rate control model based on an encoding of one or more reference image data units using one or more reference coding parameters, determining the one or more coding parameters for encoding the image data unit based on the target rate and the rate control model associated with the one or more determined model parameters, and using the one or more determined coding parameters to encode the image data unit.

摘要： A method for supporting video coding includes obtaining an image frame including a plurality of coding block groups each including one or more coding blocks, using a first coding control model associated with a first coding block group in the image frame to estimate one or more first coding parameters, using a second coding control model associated with a second coding block group in the image frame to estimate one or more second coding parameters, determining an effective coding parameter based on an evaluation of the one or more first coding parameters and the one or more second coding parameters, and using the effective coding parameter to encode the plurality of coding block groups in the image frame. The second coding control model is different from the first coding control model. The second coding block group is different from the first coding block group.
