These files are selected as the result of a mysql query from perl and sit within a number of directories along with many more images which will not form part of the video - hence I cannot use wildcards with ffmpeg (or any other tool). I can easily list all the filenames in order to a file but am unable to find a way to use this file (which currently has the full path to one jpg on each line) as input to ffmpeg. Currently the only way I have found to do this is to copy all the files (or create links) to a new directory which then allows me to use wildcards - however this seems horribly inefficient! Any thoughts or solutions welcomed! Dom
If you've got a list of jpegs in files.lis then something like for file in `cat files.lis `; do echo ffmpeg -options $file ; done should do the trick. If the ffmpeg encoding is complex then it might be cleaner to code a simple script that takes the filename as a parameter and then call that script with for file in `cat files.lis `; do ./myscript.sh $file ; done
