Crate flv_codec

Decoders and encoders for FLV file format.

Examples

use bytecodec::io::IoDecodeExt;
use flv_codec::{FileDecoder, Header, Tag};

// Reads FLV file content
let mut flv = &include_bytes!("../black_silent.flv")[..];
let mut decoder = FileDecoder::new();

// Decodes the first FLV tag
let tag = decoder.decode_exact(&mut flv).unwrap();
let header = decoder.header().cloned().unwrap();
assert_eq!(header, Header { has_audio: true, has_video: true });
assert_eq!(tag.timestamp().value(), 0);
assert_eq!(tag.stream_id().value(), 0);
match tag {
    Tag::Audio(_) => println!("audio tag"),
    Tag::Video(_) => println!("video tag"),
    Tag::ScriptData(_) => println!("script data tag"),
}

// Decodes the second FLV tag
let tag = decoder.decode_exact(&mut flv).unwrap();
