Ffmpegthumbnailer doesn't work on fedora silverblue 38

[Froggy232]

Hi,
First, thanks you for your work!
I was using ffmpegthumbnailer flawlessly on archlinux then on fedora silverblue 37, but since I have upgraded to fedora silverblue 38, it doesn't work anymore.
I have tried to launch ffmpegthumbnailer from a terminal with this command : "ffmpegthumbnailer -i Filename.mkv -o Test" but it doesn't work, it tell me that :

Error: basic_string::substr: __pos (which is 18446744073709551615) > this->size() (which is 4)

Does someone have an idea?
Thanks you

Same here. Silverblue 38 is not installing dependencies. #223

Silverblue 38 install

$ rpm-ostree install ffmpegthumbnailer

Workaround:

rpm-ostree override remove libavcodec-free \
                           libavfilter-free \
                           libavformat-free \
                           libavutil-free \
                           libpostproc-free \
                           libswresample-free \
                           libswscale-free \
                           --install ffmpegthumbnailer

Error: basic_string::substr: __pos (which is 18446744073709551615) > this->size() (which is 4)

This error occurs when the output filename is too short. Try a longer one and you might encounter the real error.
