I’m trying to set up Julia on my work computer and encounter a LoadError when I try to precompile Plots.jl. Help would be much appreciated!

I’m on Windows 10 and use Julia 1.7.2.

Try installing ffmpeg separately on Windows and then try installing the package again. The avcodec-58.dll file is provided by ffmpeg.

I have never heard of ffmpeg before this. Is [this](https://ffmpeg.org/) is?

That won’t help anything, `avcodec-58.dll` is _already_ there as clearly shown by the error message.

@fredrikpaues what version of Windows do you have? Is it by any chances one of those versions without audio/video support?

I listened to Spotify through my headphones just an hour ago, so I would say no 🙂 It’s Windows 10 Enterprise N LTSC version 1809.

Try this:

```julia
]add https://github.com/giordano/DependencyWalker.jl
using Plots # this will result in an error, it's ok
using DependencyWalker
Library(raw"C:\Users\frpa8185\.julia\artifacts\ecb81e6429c089c1da802644fae337754832d534\bin\avcodec-58.dll")

```

The last command _should_ show which library can’t be found.

I hope that I did it. I’m currently on the subway running my work computer over Remote Desktop from my cell phone 🙄

I’m moderately sure that means you’re missing some Windows package to play audio/video

Installing [the media feature pack](https://support.microsoft.com/en-us/help/3145500/media-feature-pack-list-for-windows-n-editions) solved the issue. It might be helpful to put a warning in the Readme if this can be reproduced.

Looks like you’re indeed in the same situation.

Which means it’s a different problem, since the problem above was _very_ specific to Windows. Mind opening a new thread, providing more details about your system (what version of macOS? What architecture?), version of Julia (output of `versioninfo()`), how you installed it, etc?
