+# Example FLV plugin for VLC media player, written in Rust
+
+This project generates a dynamic library that can be loaded directly
+by VLC media player. It recognizes FLV file, thanks to the
+[flavors nom parser](https://github.com/Geal/flavors), written with nom.
+
+It also uses a [separate project](https://github.com/Geal/vlc_module.rs)
+to import VLC function definitions and some helper macros.
