 Replying to [comment:4 cehoyos]:
 >> Yes, sample video is 25 frames, 1 second. Then use `-stream_loop 1`,
 >> output video is 50 frames(with movie), 2 seconds.
 > This is the intended behaviour, no?
 Yes, this is the intended behaviour(1 + 1*1 = 2 seconds).

 Replying to [comment:5 mulvya]:
 > I just noticed, the jump is related to the video framerate. If the rate
 is
 > X fps, the timestamps jump is X seconds at the joints.
 I confirmed. This is right. 1+1*1+60(fps) = 62 seconds
