I am trying to get GLMakie record to work.

Trying the example code from [http://makie.juliaplots.org/stable/animation.html:](http://makie.juliaplots.org/stable/animation.html:)

```julia
using GLMakie
using Makie.Colors

fig, ax, lineplot = lines(0..10, sin; linewidth=10)

# animation settings
nframes = 30
framerate = 30
hue_iterator = range(0, 360, length=nframes)

record(fig, "color_animation.mp4", hue_iterator; framerate = framerate) do hue
    lineplot.color = HSV(hue, 1, 0.75)
end

```

Results in a window opening with the plot, but saving the animation to a movie file fails. Error given is:

```julia

```

I’m looking for advice how to debug where this error is coming from.

Thanks,

Seems like a platform specific issue…  
If you have some time, this should be an MWE to debug the problem:

```julia
using FFMPEG, Colors
using Colors: N0f8
process = @ffmpeg_env open(`$(FFMPEG.ffmpeg) -framerate 30 -f rawvideo -pixel_format rgb24 -r 30 -s:v 500x500 -i pipe:0 -vf vflip -y test.mkv`, "w")
write(process, rand(RGB{N0f8}, 500, 500))
close(process)
wait(process)

```

Thanks a lot for the quick reply!

This test gives me the error below. Unfortunately, I still don’t see what is wrong. ffmpeg seems to get invoked fine, but perhaps I am missing something.

I see a “WARNING: library configuration mismatch” in the output, trying to find out where that is coming from. Not sure if it is relevant or not.

A simple ffmpeg command like

```julia
ffmpeg -loop 1 -i test.png -c:v libx264 -t 15 -pix_fmt yuv420p -vf scale=320:240 out.mkv

```

works fine (video is created fine), so my ffmpeg setup is not completly broken at least…

I noticed that julia is using its own version of ffmpeg, not the one my system has installed.

For testing, I removed that version (by deleting the ffmpeg file from .julia/artifacts…) and at least the test code you provided works now.  
(I cannot play the video, but I have the same issue with any video I create with ffmpeg and pix\_fmt rgb24)

When using the code from the tutorial using “record” I get this error now:

```julia
ERROR: LoadError: IOError: could not spawn `/home/ben/.julia/artifacts/7f40eeb66d90d3026ae5fb68761c263b57adb840/bin/ffmpeg -loglevel quiet -i '/tmp/jl_OF6ZyS/##video#264.mkv' -crf 20 -c:v libx264 -preset slow -r 30 -profile:v high422 -pix_fmt yuv420p -c:a libvo_aacenc -b:a 128k -y /tmp/jl_SAsXCJ/out.mp4`: no such file or directory (ENOENT)

```

which is not very surprising, since I removed it, I was hoping it would default to my system ffmpeg automatically.

I have something to work with now at least, trying to find out why the version that comes from julia does not seem to work on my system.

For now, my workaround is to symlink/.julia/artifacts/7f40eeb66d90d3026ae5fb68761c263b57adb840/bin/ffmpeg to /usr/bin/ffmpeg.
