Summary of the bug:
How to reproduce:
{{{
% fmpeg -ss 10 -i /home/pgunn/caiman_data/example_movies/msCam13.avi -ss
10 -loglevel info -vf scale=752:480 -sws_flags bicubic -pix_fmt rgb24
/tmp/foo_noprelinear.avi
ffmpeg version (tested on 5.x and 6.x on various platforms
}}}
With that initial `-ss` all the frames of the output movie are 0 (for this
input).
Without it (just with the latter `-ss`, the output looks fine.
There are no interesting warnings that the "info" level of logging outputs
with our files (datafiles generated directly by microscopes).
You may find one of these datafiles here (no need to register or anything,
just use wget):
