[SimonDanisch]

This is super weird, since that can only happen if build fails, but that should then error earlier... so maybe a corrupted deps file.
Anyways, that interpolation is wrong so I opened: #13

[SimonDanisch]

can you try to checkout master and run ]add FFMPEG#master; build FFMPEG; test FFMPEG ?

I had the same issue but this fixed it for me!

[SimonDanisch]

Oh it did? :D I just figured, that I didn't fix it on master, but I think I've found the actual problem now...

[floswald]

i also had problems with this. checking out master as above works for me! thanks.

[kongdd]

I have the same problem. Can't solve by the above solutions

[giordano]

@kongdd what operating system are you using? After checking out master, did you rebuild the package and restart julia?

[kongdd]

win10 x64

[SimonDanisch]

Can you post the log for ]build FFMPEG?

[kongdd]

Thanks in advance!

ok, can paste the output of:

using Libdl
FFMPEG = raw"C:\Users\kongdd\.julia\packages\FFMPEG\4fpOR"
bindir = joinpath(FFMPEG, "deps", "usr", "bin")
join(stdout, readdir(bindir), "\n")
Libdl.dlopen(joinpath(bindir, "avformat-58.dll"))

[SimonDanisch]

You may need to adjust the names / paths, I'm not on windows atm, so couldn't actually run this ;)
@giordano, is there an easy way to do your magic to figure out what avformat is missing?
