Comment (by AlexSmith):
Replying to [ticket:2874 jlubeck]:
> 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.
It is possible to read the image's metadata and draw it on top of each
frame by using the 'drawtext=' filter. For example, to read the DateTime
metadata from each frame, one can use:
{{{
drawtext="text='%{metadata\:DateTime\:def_value}'"
}}}
Currently there's no way to print the input file name, unless some
additional steps are taken, like shown here:
