mkvmerge doesn't work on windows

[nisehime]

I'm trying new mkvmerge thing and looks like it doesn't work. I have this error

mkvmerge v66.0.0 ('Josie') 64-bit
'C:\Users\Madobe\AppData\Local\Temp\tmpo85ouo_x/temp.webm': Using the demultiplexer for the format 'Matroska'.
'C:\Users\Madobe\AppData\Local\Temp\tmpo85ouo_x/temp.webm' track 0: Using the output module for the format 'VP8/VP9'.
Error: The file '\\?\F:\gallery-dl\galleries\pixiv_work\28155160 (user_wfaj5742)\97523646_p0.webm' could not be opened for writing: create_directory() failed.

Maybe it's something about \\?\ in the path

Wrong repo?

It works fine if I do it manually, so it's either gallery-dl doing something wrong or something about permissions (but I really have no idea and ffmpeg doesn't have this issue)

That was it. Should be fixed with 3524c59.

Wrong repo?

Ah, understand. The original post was a bit, well, minimalistic..
Edit:
I'd still consider this a bug in mkvmerge, to be honest.

Thanks, it's working

Also, I think it'd be nice if gallery-dl showed an error in the log when ffmpeg or mkvmerge fails to make ugoira. Because you can easily miss it right now, especially when you set ffmpeg output to false.
