Description

A pure OCaml library for reading files from various formats.

Added to opam-repository:

README

The metadata library

A pure OCaml library to read metadata from various formats. For now, are supported:

  • audio formats: ID3v1 and ID3v2 (for mp3), ogg/vorbis, ogg/opus, flac and wav
  • image formats: jpeg and png
  • video formats: mp4 and avi
  • text formats: pdf

Usage

Basic usage is

let () =
  let metadata = Metadata.parse_file "test.mp3" in
  List.iter (fun (k,v) -> Printf.printf "- %s: %s\n" k v) metadata

In the above example, the function Metadata.parse_file takes a file name as argument and returns an association list describing its metadata. It consists of pairs of strings being the name of the metadata and its value.

Installing

The preferred way is via opam:

opam install metadata

Build status

Results of building metadata with each compiler on check.ci.ocaml.org, run of against opam-repository 8a77e58. All results for this package.

Each result links to its build log. To keep crawlers from overloading the site, build logs require a GitHub sign-in (see ocurrent/opam-health-check). On your first log, GitHub asks you to “Authorize opam-health-check”, the OCurrent app that runs these checks; it sees only your public profile, not your repositories. The sign-in lasts 30 days.
