The present disclosure provides a live video broadcast method and apparatus, and a storage medium. The method includes: receiving a live broadcast command, and creating a video buffer based on the live broadcast command; binding the video buffer with a picture drawing module, the picture drawing module being configured to detect and extract a video picture frame; detecting and extracting the video picture frame by using the picture drawing module, and storing all extracted video picture frames in the video buffer; collecting an external voice by using a microphone, and synchronously synthesize the external voice and the video picture frames stored in the video buffer into a video streaming media file; and uploading the video streaming media file to a live broadcast server, so that the live broadcast server performs live broadcasting.
