Avconv - Passing a list of image paths

I want to write a script that will generate a timeline video based on a given input of image file paths. I understand that you can do something like this:

avconv -r 15 -i %04d.JPG -s hd480 -vcodec libx264 time-lapse.mp4

This will search for files in the directory based on the file name template 0000.JPG, 0001.JPG etc. However, I am trying to figure out if there is a way to pass it in the list of file names in the order I want to process? My ideal situation is that I can execute some DB query to get a list of image file paths in chronological order, and then pass them to the avconv command and make it generate video on the fly. I have a specific folder structure for my images, so I would not want to copy the necessary files to the temp directory in order to be able to name them correctly and then process them.

This is also the only way to make me work (image2pipe trick doesn't work for me).

  • Create a folder with the images you want in your movie.

  • Rename files (do not forget to backup your images earlier in case of error)

     aa=0;for i in `ls`; do mv $i `printf "%04d" $aa`.png; aa=$(($aa+1));done

  • Run avconv

     avconv -f image2 -i %04d.png -b 2500k -codec mpeg4 Heligyro.avi

I ended up creating piping ls to create links, and then to create links.

 x=0; for i in $(ls -t *JPG); do counter=$(printf %05d $x); ln -s "$i" "$counter".jpg; x=$(($x+1)); done
