Embodiment Construction
[0062] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0063] The present invention will be described in further detail below in conjunction with specific examples, and these examples should not be construed as limiting the scope of protection claimed by the present invention.
[0064] The following describes the video decoding method, device and computer equipment according to the embodiments of the present invention with reference to the accompanying drawings.
[0065]First, briefly introduce the video codec technology. The encoder encodes multiple images and outputs them into GOP (Group of Pictures) segment by segment, while the decoder reads and decodes the above GOP during playback, and then reads the image and renders it for display. Wherein,...

The invention discloses a video decoding method, a video decoding device and computer equipment. The video decoding method comprises the following steps: acquiring a to-be-decoded video, and determining a key frame in the to-be-decoded video; determining a to-be-selected frame and a to-be-decoded frame from the to-be-decoded video according to the frame selection frequency and the key frame; and respectively decoding the to-be-selected frame and the to-be-decoded frame by adopting different decoding modes. According to the video decoding method and device and the computer equipment, the to-be-decoded video is acquired, the key frame in the to-be-decoded video is determined, the to-be-selected frame and the to-be-decoded frame are determined from the to-be-decoded video according to the frame selection frequency and the key frame, and the to-be-selected frame and the to-be-decoded frame are decoded by adopting different decoding modes respectively. Therefore, the video decoding calculation pressure is relieved, the calculation resource waste is avoided, and the decoding efficiency is improved.
Description
technical field [0001] The present invention relates to the technical field of video decoding, in particular to a video decoding method, device and computer equipment. Background technique [0002] A video is a continuous image sequence consisting of consecutive frames, and a frame is an image. Due to the persistence of vision effect of the human eye, when the frame sequence is played at a certain rate, what people see is a video with continuous actions. However, the data volume of simple video transmission is very large, and the requirements for network and storage are relatively high. Due to the extremely high similarity between consecutive frames, the original video can be encoded and compressed to facilitate storage and transmission, and a large amount of repeated information can be removed, which can reduce the amount of video data. Mainstream video coding formats include H.264, MPEG, RMVB, etc. When playing and watching a video, the encoded video needs to be decoded...
