Multimedia data processing method and device, electronic equipment and storage medium

The invention relates to a multimedia data processing method and device, electronic equipment and a storage medium, and relates to the technical field of Internet. According to the embodiment of the invention, the problem that the closed live broadcast data stream in the preloaded live broadcast data stream cannot be updated in time in the related technology is at least solved. The method comprises the following steps: acquiring a first data stream corresponding to a resource preview page, wherein the first data stream comprises a first number of preloaded live broadcast data streams; if it is detected that a second number of closed live broadcast data streams exist in the first data streams, sending first request information used for pulling the live broadcast data streams; acquiring a second data stream sent in response to the first request information; the second data stream comprises a third number of live broadcast data streams which are live broadcast except the first number of live broadcast data strea
