Abstract: This application belongs to the technical field of communication, and particularly relates to a video coding method and apparatus, a computer-readable medium and an electronic device. The video coding method, executed by the electronic device, includes obtaining historical signal strength information within a historical time period, the historical signal strength information representing a video transmission wireless network signal strength corresponding to each moment of the historical time period; predicting strength information of a next key frame according to the historical signal strength information, the strength information of the next key frame representing a wireless network signal strength for transmitting the next key frame; and determining a target data volume of the next key frame according to the strength information of the next key frame, and performing intraframe coding on the next key frame according to the target data volume.

Abstract: This application discloses a data transmission method performed by a computer device. It is detected that the ith forward reference frame is lost, during video decoding, when the (i+T+1)th forward reference frame is decoded, since a video frame in a first reference frame combination of the (i+T+1)th forward reference frame is located before the (i+T+1)th forward reference frame with an interval of T forward reference frames from the (i+T+1)th forward reference frame, T being a positive integer, so that before the (i+T+1)th forward reference frame is decoded, there is more time for retransmitting the ith forward reference frame, improving a possibility of completing retransmission of the ith forward reference frame during decoding of the (i+T+1)th forward reference frame, thereby reducing a possible waiting time for decoding the (i+T+1)th forward reference frame.

Abstract: A video stream processing method is provided. A first group of coded picture frames in a video stream is received. A storage time and a network request protection time corresponding to the first group are determined. The storage time is an amount of time an intra frame of the first group is stored for transmission to a network node. When a transmission conflict with at least one second terminal occurs in a process of transmitting the intra frame to the network node, a start time of at least a second group of coded picture frames in the video stream is determined according to the storage time and the network request protection time, the second group being after the first group. An intra frame of the second group is transmitted to the network node based on the start time of the second group.

Abstract: A multi-channel data transmission method includes dividing a plurality of data packets including at least one input data packet into a plurality of groups including a target group that includes the at least one input data packet, determining a target channel pair, for the target group, including a primary transmission channel and an auxiliary transmission channel that are established based on different networks, performing error correction encoding on the at least one input data packet to obtain at least one output data packet and at least one error correction packet, and transmitting the at least one output data packet and the at least one error correction packet using the primary transmission channel and the auxiliary transmission channel, respectively.

Abstract: A communication method/apparatus, including accessing a signaling server to trigger bidirectional authentication between the first terminal and the signaling server, generating a video connection establishment request based on the bidirectional authentication between the first terminal and the signaling server succeeding, signing the video connection establishment request; encrypting the video connection establishment request and a signature of the video connection establishment request to obtain a first encryption result, and transmitting the first encryption result to a second terminal via the signaling server.
