Remeta

This crate provides metadata extraction for audio, video, bitmap, and vector image formats. It supports reading artist/title info, durations, resolutions, and more.

Example Usage

use std::fs::File;
use std::io::Result;
use remeta::{VideoMetadata, ImageMetadata, SongMetadata};

// Audio
let song = SongMetadata::from_file("song.mp3")?;
println!("{:?}", song);

// Video
let video = VideoMetadata::from_file("movie.mp4")?;
println!("{:?}", video);

// Images (bitmap or vector)
let video  = ImageMetadata::from_file("movie.mp4")?;
println!("{:?}", video);

Cargo Feature Flags

Enable only the formats you need to reduce compile time and binary size. Example:

[dependencies.remeta]
version = "0.1"
features = ["mp3v2", "wav", "jpg", "png", "svg"]

You can also enable all features for convenience:

[dependencies.remeta]
version = "0.1"
features = ["audio-all", "video-all", "images-all", "vector-all"]

Notes

• Durations are only computed if the corresponding -duration feature is enabled.
• Vector images may provide only width/height and format; color depth is generally unavailable.
• HEIF/AVIF detection requires the file to have a valid ISO BMFF container with the correct brand (heic, avif, etc.).
