I'm not so sure.  The original message has this paragraph:

The image should be opened, decoded, and closed for every frame so that
changes will be seen in the output stream.

An optimised solution might check for changes in file modify time or
watch for changes with a platform specific feature.  I don't think
either of these are present in ffmpeg.
