ffmpeg: File not found, but obviously is accessible
Either I'm doing some very stupid mistake, or I've stumbled upon a very strange bug here. I'm in bash, and I want to convert a .flac to a .mp3 using ffmpeg. Running
ffmpeg -i 3 - Thirty Seconds to Mars - Rescue Me.flac 3 - Thirty Seconds to Mars - Rescue Me.mp3
results in 3 - Thirty Seconds to Mars - Rescue Me.flac: No such file or directory
, although stat
and ls
both show the file with read permissions for the current user, and I can even view its contents using less
.
I suspected a problem with the filename, so I renamed the file to asdf.flac
, which worked, but ffmpeg -i asdf.flac asdf.mp3
still gives me asdf.flac: No such file or directory
.
To exclude permission issues, I already did chmod -R 777 .
to make the directory and all files world-readable and world-writable, still no chance.
Any ideas what could cause ffmpeg to not find the file, although it's obviously there?
linux bash ffmpeg filesystems file-permissions

What is the output oftype ffmpeg
? If it returns a path, what is the output offile /the/path/to/ffmpeg
? Is there something quirky about the filesystem? (e.g. FUSE).

The only way I can think that this would occur is ifffmpeg
has the set user/group ID permission. What doesls -l $(which ffmpeg)
report?

Maybe it's something weird in the filename. Can you rename the source to something simple and try operating on that?

@kamil-maciorowski pointed me to the right direction.
lukas@Server:~$ type ffmpeg
ffmpeg ist /usr/local/bin/ffmpeg
Which reminded me of a firejail
setup.
lukas@Server:~$ file /usr/local/bin/ffmpeg
/usr/local/bin/ffmpeg: symbolic link to /usr/bin/firejail
Confirmed this. So apparently ffmpeg
is running in a jail. Didn't know that I had firejail
set up on that machine, but running /usr/bin/ffmpeg
directly worked. So there is a restriction of the jail present, that doesn't whitelist input files.
