It doesn’t “do” anything because it doesn’t know the concepts of hard- and soft-telecine. It doesn’t “just” take what the decoders output, it assigns proper timestamps to the frames (as it does with all frames coming out of a decoder). If the input was soft-telecined, FFmpeg only sees progressive content, often 24000/1001 frames. Hard-telecined means 30000/1001 frames, the telecine effect can be undone if done properly. If the input contains both soft- and hard-teleconference content, FFmpeg sees variable framerate input (which it actually is).
