This application relates to a picture sharing method, a computer device, and a storage medium. The method includes: receiving a picture compressed in a first compression manner; obtaining characteristic information of the picture; compressing the picture in a second compression manner in a case that the characteristic information meets a compression trigger condition, to obtain a compressed picture; receiving a picture download request for the picture, wherein the second compression manner has a higher compression ratio than the first compression manner; and returning the compressed picture in response to the picture download request. The solutions of this application reduce a network bandwidth occupied in a picture feedback process.

Picture sharing method, computer device, and storage medium

In a video encoding method, a to-be-encoded video is obtained. The video includes at least two video frames arranged in sequence. A quantization parameter and a quantization parameter threshold of an ivideo frame is calculated, where i is a positive integer greater than or equal to 2. A coding resolution of the ivideo frame is determined according to the quantization parameter and the quantization parameter threshold. The coding resolution is a first coding resolution in a case that the ivideo frame is sampled, and the coding resolution is a second coding resolution in a case that the ivideo frame is downsampled. Then the ivideo frame is encoded at the coding resolution.

A data coding method includes determining a length of a current first bit-rate-control-unit data frame in to-be-transmitted data, and the length of the first bit-rate-control-unit data frame is less than or equal to a length of a group of pictures (GOP) data frame. The method also includes determining a first target bit rate of the first bit-rate-control-unit data frame according to the length of the first bit-rate-control-unit data frame, a target bit rate of the to-be-transmitted data, and a frame rate of the to-be-transmitted data and, when a first difference value between a real bit rate of a second bit-rate-control-unit data frame and a second target bit rate of the second bit-rate-control-unit data frame is greater than zero, adjusting the first target bit rate according to the first difference value, and coding the first bit-rate-control-unit data frame according to the adjusted first target bit rate.

Embodiments of this application disclose a picture transmission method performed at a computer device. After obtaining a picture, the computer device generates a video sequence by replicating the picture N times, and N being a positive integer. Next the computer device obtains a resolution setting sequence and encodes the N to-be-encoded pictures in the video sequence according to the resolution setting sequence to generate N encoded pictures, each encoded picture having an associated resolution setting. Finally, the computer device sends the N encoded pictures to a decoding computer device. The decoding computer device then decodes and displays the N encoded pictures according to their respective resolution settings from low to high.

The application discloses video data redundancy control methods and apparatuses. Video packet redundancy control information is determined according to packet loss at a reception apparatus. The video packet redundancy control information is received from the reception apparatus. Video data is encoded according to the video packet redundancy control information to obtain encoded video data of a plurality of frames by a transmission apparatus. A frame-level redundancy budget is allocated for one of the plurality of frames according to the video packet redundancy control information. Further, the one of the plurality of frames is packetized according to the frame-level redundancy budget to generate a packetized frame. Redundancy coding is performed on the packetized frame to generate video packets including data packets and redundant packets for transmission to the reception apparatus.
