libfdk-aac.so.1: cannot open shared object file

[ssfrr]

I'm getting an error trying to run FFMPEG (through Plots.jl) - it seems that FFMPEG isn't finding a library it's looking for.

The error I get in Julia is just

failed process: Process(`/home/sfr/.julia/artifacts/3c41de0860295a9627f2819e7d2e27275796b308/bin/ffmpeg -v 0 -framerate 10 -loop 0 -i /tmp/tmp.9vaJqzM4Lz/jl_eWbBeU/%06d.png -pix_fmt yuv420p -y /home/sfr/Dropbox/projects/papers/Dissertation/plot_gen/slf_anim.mp4`, ProcessExited(1)) [1]

Which isn't very informative as to what the actual error is, but if I run the same command from the terminal I get

I'm not actually sure that the error I'm getting when it's invoked from Julia is the same as the error I get when it's invoked from the shell, but it's not clear how to find out what the error from Julia is.

How are you running ffmpeg in Julia?

[ssfrr]

Whoops, sorry for the lack of MWE:

using Plots

anim = @animate for i in 1:10
    plot(randn(1000), size=(100,100))
end

mp4(anim, "/tmp/test.mp4")

Which gives:

failed process: Process(`/home/sfr/.julia/artifacts/3c41de0860295a9627f2819e7d2e27275796b308/bin/ffmpeg -v 0 -framerate 20 -loop 0 -i /tmp/tmp.3PASOxlEEw/jl_5eRu3l/%06d.png -pix_fmt yuv420p -y /tmp/test.mp4`, ProcessExited(1)) [1]

I think the actual issue here is JuliaPlots/Plots.jl#2158, so maybe the real issue is that ffmpeg is run with -v 0 so it doesn't give useful information when something goes wrong.

[giordano]

I want to see how the ffmpeg executable is called. The wrapper in FFMPEG_jll must be used, otherwise this kind of errors occurs.

[giordano]

Looking at the stacktrace it seems the wrapper is used?

[ssfrr]

Sorry, maybe I wasn't clear - when I run it from within Julia I get the ProcessError with the stacktrace above, but don't know what the underlying FFMPEG error is because ffmpeg is run with -v 0, which swallows the error (Also I'm not sure if there'd need to be something else done to display STDOUT).

The libfdk-aac issue was from trying to run the JLL executable from within the shell, but that's probably just because the paths weren't set up correctly due to bypassing the wrapper.

It seems that the arguments are setup within Plots though, so actually the issue is there.

Sorry for the noise, I'll close this.
