1. A method for video processing, comprising:
receiving an input video comprising a plurality of sections, and metadata associated with the input video, at least two sections of the plurality of sections of the input video having different frame rates; and
performing real-time processing on the input video according to the metadata, so as to output an output video with a constant target frame rate in real-time,
wherein, the metadata comprises information indicating the frame rate of each section of the input video or the metadata comprises information indicating the frame rate of each section of the input video, and the metadata further comprises at least one of the following information: information indicating the target frame rate and information indicating a processing operation to be used for performing real-time processing on the input video, and
wherein the target frame rate is determined by:
in the case that the metadata does not comprise the information indicating the target frame rate, determining the target frame rate based on a maximum frame rate supported by a display device displaying the output video or frame rates of the plurality sections of the input video; and
in the case that the metadata comprises the information indicating the target frame rate, determining a smaller one of the indicated target frame rate and the maximum frame rate supported by a display device displaying the output video as the target frame rate.
