 Thank you for your reply. I have known  drawtext filter cloud done as I
 wished.
 I wrote blog in Japanese. https://nico-lab.net/drawtext_with_ffmpeg/#i-3

 I hope to do especially showinfo filter the following.

 {{{
 T_DELTA       : pts difference between current and previous
 T_DELTA.FORM  : pts difference formatted with **.**ms(**.**fps)
 BITRATE       : video bitrate
 BITRATE.FORM  : video bitrate formatted with ****kbps
 KEY_INTERVAL  : interval between previous and current key frame
 COLOR_RANGE   : color range (return of av_frame_get_color_range())
 MEAN0         : mean value of plane 0 (luminance of yuv)
 MEAN1         : mean value of plane 1
 MEAN2         : mean value of plane 2
 MEAN3         : mean value of plane 3
 }}}
