i am using ffmpeg library for thumbnail image. My project runs in windows environment.
When executing the following code:
Thumbnex.create_thumbnail(url, new_url ,max_width: 64,max_height: 64)
I receive the following error in my code:
System.cmd("ffprobe", ["-show_format", "c:/Users/Salim/Desktop/Data/Elixir/Upload/d2e04a59-5fef-4f22-82d5-e0c6a1f25ea6.jpeg"], [stderr_to_stdout: true])
** (ErlangError) Erlang error: :enoent
ImageMagic and FFprobe installed on my system.

Are these in your
%PATH%? Because that is howSystem.cmd/2is looking for executables. Just installing them doesn’t necessarily add it to%PATH%.dimitarvp
First try this:
To make sure that it can indeed be invoked. If so then the
:enoenterror means that the file parameter you supplied in your OP does not exist.NobbZ
No,
:enoentis only returned when the cmd wasn’t found.If the cmd was found, and it was unable to find the file specified in its argument list, it has to communicate this fact through its exitcode, stout and stderr. You have access to the first 2 via the returned tuple then:
Of course, this is specific to
cat,ffprobemight have a different exit code or output in this case.dimitarvp
Good to know. Thank you.
