Abstract: Embodiments of this application 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 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.
