Image sequence handling in ffmpeg

Question

I need to convert an image folder with unnumbered names, like:

11.49.18.204.jpg
11.49.28.205.jpg
11.49.38.220.jpg
11.49.48.220.jpg
11.49.58.235.jpg
11.50.08.250.jpg

FFMPEG only accepts numbered inputs. The original file names are important to me. So much that I plan to overlay them on the video feed. I think I need to use SRT subtitle input with text overlay option.

I would like to know how I can make this work.

For example, this will not work

ffmpeg -i *.jpg

Answer 1

ok, apparently FFMPEG does support name globing, from ffmpeg.org/wik

ffmpeg also supports bash-style globbing (* represents any number of any characters). This is useful if your images are sequential but not necessarily in a numerically sequential order as in the previous examples.

ffmpeg -framerate 1 -pattern_type glob -i '*.jpg' -c:v libx264 out.mp4

Answer 2

If you are on Unix/Linux, this bash script line will rename a directory of image files to a series of sequential names that will work with ffmpeg. Basically it creates an in memory buffer of all the existing filenames, and then loops thru each name, moving them to an incrementally numbered name (in the same directory.

x=1; for i in *jpg; do counter=$(printf %03d $x); mv "$i" img"$counter".jpg; x=$(($x+1)); done
