VLC-GIF-Maker on Windows tries to create output file with a slash (/). Gif extension is not added to the output filename

Unfortunately, no matter what I write on the settings, the output path (is shotly overlaid on the video) is like:
"C:\temp/g172345556" (note the /)
Settings used: ffmpeg -ss {start_timestamp} -to {stop_timestamp} -i "{input_file}" -vf "fps={fps},scale=498:-1:flags=lanczos,split[s0][s1];[s0]palettegen[p];[s1][p]paletteuse" -loop {loop} "{output_path}{output_filename}" (actually it does not matter whether I put a backslash or a slash between {output_path} and {output_filename}
output_path: C:\Temp
output_filename:

How random. What are the odds! I just stumbled over this repo and precise issue just now.

Yes, I can reproduce, and I thought this is the reason I don't get an output. In fact, after pushing "generate GIF" the terminal pops up for a split of a second but even logging and pausing the script did not return anything.

How did I solve the issue: As written in the README.md you need FFmpeg to be installed and accessible from PATH / environment variable. I used a pre build version (e.g. https://github.com/GyanD/codexffmpeg/releases) and added the extracted archive to PATH (C:\path\to\your\ffmpeg\bin). Note: PATH expects the directory where the executable is located (ffmpeg.exe).

Now I can generate the GIF. Nice work btw.

The output path for Windows should be changed to the correct directory separator.
And I would have loved to have a check and a note in the terminal that FFmpeg needs to be installed first. For everyone that just skims over the README like me 😅
I'm no LUA expert at all but something like os.execute('where ffmpeg'). And depending on the return value, inform the user about the missing tool. Or there could even be a check for the FFmpeg version in the same call, if a min version is required. Like os.execute('ffmpeg -version')

@RobertZickler Unfortunately VLC doesn't allow to fetch a response from shell commands, only to execute them - that was actually the first function I started to write. You can't even get a status code
The directory separator is changed depending on the platform while generating the command, is it not correct?
