In order to test `Plots.jl`’ `gif` creation in Travis, i.e. something like this:
```julia
using Base.Test, Plots
anim = @animate for i=1:2
plot(rand(2))
end
name = tempname()*".gif"
gif(anim, name)
@test isfile(name)
```
we have to somehow add `ffmpeg` as a dependency (e.g. in the `.travis.yml` file, or via `BinDeps.jl`). **Does anyone know exactly how this is done?**

Does adding something like
```julia
before_install:
- if [["$TRAVIS_OS_NAME" == "linux"]]; then wget https://launchpad.net/~mc3man/+archive/ubuntu/trusty-media/+files/ffmpeg_3.3.3~trusty2_amd64.deb ; fi
- if [["$TRAVIS_OS_NAME" == "linux"]]; then sudo dpkg -i ffmpeg_3.3.3~trusty2_amd64.deb ; fi
```
in `travis.yml` work?
Note that this is just a guess based on how Plots.jl installs wkhtmltox on travis for the tests. (See [https://github.com/JuliaPlots/Plots.jl/blob/master/.travis.yml#L21](https://github.com/JuliaPlots/Plots.jl/blob/master/.travis.yml#L21) and [https://github.com/JuliaPlots/Plots.jl/blob/master/test/install\_wkhtmltoimage.sh](https://github.com/JuliaPlots/Plots.jl/blob/master/test/install_wkhtmltoimage.sh))

Interesting. But I got this error:
```julia

```
I’ll see if I also can make a small bash file for `ffmpeg`, but how would one solve this for the mac Travis?

You could also try something like
```julia
sudo add-apt-repository ppa:mc3man/trusty-media
sudo apt-get update
sudo apt-get install ffmpeg
```
in the bash file. I have no idea about mac though.

Fixed! Thanks @daschw!!!
I ended up using this:
```bash
#!/bin/sh
sudo add-apt-repository -y ppa:mc3man/trusty-media
sudo apt-get -qq update
sudo apt-get install -y ffmpeg
```

Am I to understand from [this](https://github.com/JuliaPlots/Plots.jl/blob/master/.travis.yml#L5) that `Plots.jl` is not supported on macs? 😱

This has been that way before I joind the JuliaPlots team - not sure why… I will take a look at what the issue with travis on mac is.

I guess part of the problem is the installation of ffmpeg.

This line in `.travis.yml` finally solved it:
```julia
- if [["$TRAVIS_OS_NAME" == "osx"]]; then brew install ffmpeg cairo; fi
```
