Abstract: A method for storing video data includes, when receiving the I-frame data to be stored, detecting whether the written data exists in the video cache space; when detecting that the written data exists in the video cache space, reading a target writing position of the I-frame data to be stored and determining whether the target writing position is located within a position range corresponding to the written data in the first cache space; when determining the target writing position is located within the position range, writing, based on the target writing position, the I-frame data to be stored to the first cache space for caching and detecting whether the first cache space is full; and when detecting that the first cache space is full, writing all the video data in the video cache space to a memory space of the terminal device for storage and emptying the video cache space.
