How to programatically generate video of a number or countdown
27 novembre 2013, par xorsystI've got some python that drives ffmpeg to convert some videos and do other processing. I'd like to prepend the videos with a couple of seconds of a number, and append a short countdown timer video.
Each video could have different values for the numbers and length of countdown. Is there an easy programatic way to generate this sort of video ? I was thinking of perhaps coding some wxpython to generate the required stuff, but how to save that out as a video file or stream it to ffmpeg ?
Ideas welcome - doesn't have to involve Python, external programs (Windows) are ok.

ffmpeg showing wrong frame number on drawtext output
24 février 2024, par Ricardo BohnerI'm using the following command to save each frame as picture with the frame number printed on it :


ffmpeg -i input.mp4 -vf "drawtext=text='%{n}':fontsize=72:fontcolor=white:borderw=3:bordercolor=black" -fps_mode vfr "pics\%5d.jpg"



It seems to have worked out ok, but when I go throught the pictures about at frame 930 the framecount simply restarts back to 0 and goes counting on from there again. I have tried to regenerate pts option -fflags +genpts to no avail. Any ideas ?
