I'm trying to create a video watermark layer using two input : one image and one series of images.
Thus using the last version from osx (2.5.3 and 2.5.2), I've noticed that the encoding never end and the file keeps growing and growing.

How to reproduce:

% ffmpeg -loop 1 -shortest -i images/image001.png -i images/test%04d.png -filter_complex overlay testvid.mp4

-shortest is an output option as shown in the documentation. I expect that you should have received a message in your console output:

Option shortest (finish encoding within shortest input) cannot be applied to input file image001.png -- you are trying to apply an input option to an output file or vice versa. Move this option before the file it belongs to.
Error parsing options for input file image001.png.
Error opening input files: Invalid argument

However, when using overlay with a looping input you need to use shortest=1 within the overlay filter, such as overlay=shortest=1. See the overlay video filter docs for more info.

Note: See TracTickets for help on using tickets.
