I'm creating a timelapse which I would love to include the "timecode" of
when each picture was taken.
Currently, the timecode option creates one for everyframe of the video.
Also, using text='\%T' seems to work only for real-time streams.
I have files named:
2013-08-16_001032.jpg
2013-08-16_002045.jpg
2013-08-16_003024.jpg
2013-08-16_004043.jpg
and so on... That is year-month-date_hourminutesecond.jpg
I'm currently using the following:
% ffmpeg -y -i "2013-08-14_%*.jpg" -vf
"drawtext=fontfile=/Library/Fonts/AppleGothic.ttf:
text=%{n}:expansion=normal: r=25: x=(w-tw)/2: y=h-(2*lh): fontcolor=white:
box=1: boxcolor=0x00000000@1" output.m4v
And it is printing a new number on each frame. It would be great if
instead of %{n} we could use something to grab the filename, or even
better, meta data from the jpg to be able to format the timestamp. But
just with the file name would be great.
ffmpeg version 1.2.1
Thanks!
