help me,please

[SimonDanisch]

I think, these are the same issues:
JuliaGL/GLFW.jl#198
JuliaLang/julia#34276

[prehonor]

I think, these are the same issues:
JuliaGL/GLFW.jl#198
JuliaLang/julia#34276

Thank you ,I find out the issue: old version FFMPEG.jl doesnt take LD_LIBRARY_PATH of the system , so I change it from
const execenv = ("LD_LIBRARY_PATH" => string(libdir1, ":", libdir2, ":", libpath)) to
const execenv = ("LD_LIBRARY_PATH" => string(get(ENV, "LD_LIBRARY_PATH", ""),":",libdir1, ":", libdir2, ":", libpath))
