I have one question about ffmpeg transcoding:

Does ffmpeg support changing resolution transcoding?

For example, I have one fmp4/mp4 file that consists of two part, where 1st part is of 1280x720, and 2nd part is of 640x480. Does ffmpeg have the capacity such that ffmpeg can transcode 1st part into 1280x720 video stream, and 2nd part into 640x480 video stream, and save the two output parts into one single fmp4/mp4 file. Does ffmpeg support this function?
