Since version 2.1, opam now handles external dependencies alongside OCaml ones, and the `depext` plugin interface is provided for backwards compatibility only. Consider using your usual `opam install` command to install both OCaml and system dependencies, or `opam install <pkg> --depext-only` if you want to only install external dependencies.
# Detecting depexts using vars: arch=x86_64, os=linux, os-distribution=debian, os-family=debian
# The following system packages are needed:
libavformat-dev
libavutil-dev
libswscale-dev
pkg-config
[NOTE] Package host-arch-x86_64 is already installed (current version is 1).
[NOTE] Package ocamlfind is already installed (current version is 1.9.6).
The following actions will be performed:
  - install conf-pkg-config 3
  - install ffmpeg          0.2.0
===== 2 to install =====

The following system packages will first need to be installed:
    libavformat-dev libavutil-dev libswscale-dev pkg-config

-   --no-cache                        do not cache already seen packages when
-                                     walking the dependency graph
-   --log-file=filename               write an audit log to a specified file
-   --with-path=path                  adds a directory to the search path
-   --define-prefix                   override the prefix variable with one that is guessed based on
-                                     the location of the .pc file
-   --dont-define-prefix              do not override the prefix variable under any circumstances
-   --prefix-variable=varname         sets the name of the variable that pkgconf considers
-                                     to be the package prefix
-   --relocate=path                   relocates a path and exits (mostly for testsuite)
-   --dont-relocate-paths             disables path relocation support
- 
- cross-compilation personality support:
- 
-   --personality=triplet|filename    sets the personality to 'triplet' or a file named 'filename'
