FFMPEG video (mp4) to image sequence with the time in the filename [closed]
7 juin 2013, par Ewald Bosi have a question and can't find the answer perhaps you can help ?
I am using FFMPEG (windows enviroment) and convert a video (mp4) to a series of images based on scene detection (i-frames) and add the timecode inside the image (burn) like this ;
ffmpeg -i video.mp4 -vf "drawtext=fontfile=trebucbd.ttf: timecode='00\:00\:00\:00': r=25: x=(w-tw)/2: y=h-(2*lh): fontcolor=white: box=1: boxcolor=0x00000000@1, select=eq(pict_type\,I)" -vsync 0 -an iframes/%06d.jpgAll this works perfect but i also would like to add the timecode in the filename, so instead of naming it 000001.jpg, 000002.jpg i would like to have 00.00.00.01.jpg, 00.00.00.17.jpg and thoughts about this ?
