Multimedia resource detection method and device, terminal and storage medium

The invention provides a multimedia resource detection method and device, a terminal and a storage medium. The method comprises the following steps: acquiring a target multimedia resource; determining a target resource type of the target multimedia resource, and determining a target frame extraction strategy corresponding to the target resource type; and performing frame extraction on the target multimedia resource according to the target frame extraction strategy to obtain a video frame set comprising at least one video frame. According to the method and the device, the target frame extraction strategy for the target multimedia resource can be determined according to the target resource type of the target multimedia resource, so that the target frame extraction strategy is utilized to perform frame extraction operation from the target multimedia resource with relatively complicated content, and the video frame set is obtained; after the video frame set is sent to the terminal and displayed, a detector can ch
