There might be two issues here:
1. libffmpeg-ocaml apparantly has stricter FFmpeg dependencies than the
shlibs-generated ones due to depending on additional ABI details (why?).
2. liquidsoap does not have a dependency on libffmpeg-ocaml-<ABI>.

There is an upstream release that fixes the actual build failure that I
have staged in git. However, I'm still unsure why dh-ocaml isn't picking
up the ffmpeg dependency and adding it in as I would expect. All my
investigation seems to point to ffmpeg support being included in the
build, and so the dev dependency is correctly found by dune's build
process. It then doesn't seem to make it into dh_ocaml's output variables.
If anyone has any insight into why dh_ocaml isn't doing what I expect,
that would be most appreciated.
Cheers
