  • Patent number: 12200247
    Abstract: Embodiments of this disclosure provide a method for transmitting a video picture, a device for sending a video picture, and a video call method and device, where the video picture includes a plurality of video frames. According to the method for transmitting a video picture, the plurality of video frames are encoded to obtain an encoded bitstream, where the bitstream includes at least information indicating inter-frame reference relationships. In this application, each of N frames preceding to a current frame references a forward long-term reference (LTR) frame that has a shortest temporal distance to each of the preceding N frames, and the forward LTR frame is an encoded video frame marked by a transmit end device as an LTR frame.

  • Publication number: 20240430411
    Abstract: Embodiments of this application provide an encoding method, a decoding method, and an electronic device. The method includes: obtaining a current frame; obtaining a reconstructed picture corresponding to a reference frame of the current frame from an external reference list of an encoder, where the reference frame of the current frame is a frame encoded by the encoder, and the external reference list is independent of the encoder; performing, by the encoder, intra coding on the reconstructed picture; and performing, by the encoder, inter coding on the current frame based on a result of the intra coding, to obtain a bitstream corresponding to the current frame. In this way, the encoder may flexibly select a reference frame from the external reference list for encoding, thereby implementing cross-frame reference or cross-resolution reference, and improving flexibility of reference frame management of the encoder.

  • Publication number: 20240220469
    Abstract: A message processing method includes displaying a message aggregation interface corresponding to a session interface, where the message aggregation interface includes a plurality of messages classified and displayed based on a message type, and the plurality of messages are all messages in the session interface; receiving a first input of a user for at least one first message in the plurality of messages; in response to the first input, selecting the at least one first message; receiving a second input of the user; and in response to the second input, performing a target operation on the at least one first message, where the target operation corresponds to the second input.
