Abstract

The invention relates to the field of video coding and decoding, and provides a frame type determination method and device, electronic equipment and a storage medium. The method comprises the following steps: when the type of a current video frame is unknown, calculating coding statistical information of the current video frame according to the position of the current video frame in a plurality of video frames with unknown types included in a video frame sequence and a preset reference relationship, and calculating coding characteristic parameters of the current video frame according to the coding statistical information; determining a threshold value according to the position and the coding characteristic parameter; judging whether the current video frame meets a frame type judgment condition or not according to the position, the coding characteristic parameter and a threshold value; and when the frame type judgment condition is met, determining that the current video frame is a P frame, otherwise, determining that the current video frame is a B frame. According to the frame type determination method provided by the embodiment of the invention, the representation of the coding feature parameter on the coding feature of the current video frame is more accurate, and the accuracy of frame type determination can be improved while the high efficiency of frame type determination is ensured.
