Function nom_exif::parse_metadata

pub fn parse_metadata<R: Read + Seek>(
    reader: R
) -> Result<Vec<(String, EntryValue)>>

Analyze the byte stream in the reader as a MOV/MP4 file, attempting to extract any possible metadata it may contain, and return it in the form of key-value pairs.

Please note that the parsing routine itself provides a buffer, so the reader may not need to be wrapped with BufRead.

Usage

use nom_exif::*;

use std::fs::File;
use std::path::Path;

let f = File::open(Path::new("./testdata/meta.mov")).unwrap();
let entries = parse_metadata(f).unwrap();

assert_eq!(
    entries
        .iter()
        .map(|x| format!("{x:?}"))
        .collect::<Vec<_>>()
        .join("\n"),
    r#"("com.apple.quicktime.make", Text("Apple"))
