The invention discloses a code rate control method, device and equipment for ultra-high-definition video live broadcast and a storage medium, and aims to solve the problems of easy packet loss and large code rate fluctuation of an existing ultra-high-definition video code rate control method, a self-adaptive cache is added between an encoder and a client, a preset number of audio and video frames in the encoder are obtained, and the audio and video frames are sent to the client through the self-adaptive cache. Writing the data into an adaptive cache to serve as buffer data; according to a preset target code rate, calculating the data volume required to be read from the adaptive cache in the current time period, judging whether the read data volume is smaller than the received audio and video data volume, if so, calculating the unread data volume in the adaptive cache, and if not, sending the data volume to the adaptive cache; judging whether the unread data volume is smaller than the read data volume * the da
