Windows: Long path Path causes error

[jddcef]

Hi, I have an error when working on a long/deep path.

If I move the file to c:\temp\t.mp4 it works fine.

Could you improve the handling of this so that it is clear how to fix the issue?

Great software by the way.

could the issue be due to the special quotes “? e.g. “I Need Thee Every Hour”. Does it work if you remove those?

[jddcef]

Nope, it's not the quotes ", it works fine with that name with quotes when it's in a shorter folder depth or path.
I tested it now, it's caused by too long a path and filename combined. > 255 or such.

[mifi]

Ok, I'm thinking this is related to some windows file system issue. Which version of windows are you running? And what is the file system on c:?

[jddcef]

It's NTFS on Windows 10 20H2.
It seems it's some weird issue in windows: https://stackoverflow.com/questions/1857335/is-there-any-length-limits-of-file-path-in-ntfs

[mifi]

I have found that the issue is that ffmpeg doesn't seem to support paths longer than 260 on Windows. There's still an open issue:

• https://trac.ffmpeg.org/ticket/8885?cversion=1&cnum_hist=2

Seems like a workaround is to add a prefix \\? before the path. Not sure if this works with ffmpeg. Someone with ffmpeg on windows needs to test this. e.g.:

c:\mymedia -> \\?\c:\mymedia

• https://emby.media/community/index.php?/topic/91634-problem-long-pathslong-filename-259-characters-ffprobe-error/

[mifi]

Have now added a check for output file length on windows

[jddcef]

Seems like a workaround is to add a prefix \\? before the path. Not sure if this works with ffmpeg. Someone with ffmpeg on windows needs to test this. e.g.:

c:\mymedia -> \\?\c:\mymedia

I can't seem to add the prefix without it saying folder name not valid..
And I can't see anyway in the app to manually edit the output path for example to add the "\?" at the front of it to test it out

[mifi]

if you can test ffmpeg.exe from the command line with such a path and confirm that it works that would be great

[jddcef]

if you can test ffmpeg.exe from the command line with such a path and confirm that it works that would be great

ffmpeg -i "\\?\c:\temp\t.mp4" \\?\c:\temp\t2.mp4

Yes, this command works fine with the ffmpeg 4.4.1 in LosslessCut 3.4.2
