also, it seems documentation and actual behavior still allow loading
'empty' toc file and corresponding image files:


The resulting directory of images can be opened for reading by simply
opening the template path. As in: File → Load Files
/tmp/tiff_images/img%03d.tiff. You will notice a file named the same as the
template, which has been automatically created, is empty, is needed, and
has to remain with the set.


it works for me, loading 3 bmp images on timeline...

file not completely empy, just does not contain file paths...

if this loading works may be documentation can be improved? by saying this
ffmpeg toc file not the same as usual image sequence toc file?
