Rflv is an encoder-decoder for FLV written purely in Rust.
Rflv can create/read FLV files, and can also directly generate FLV tags in cases where the user works directly with FLV tags (e.g., RTMP).
RFLV is simply an implementation of FLV for Rust; it is not an implementation of a decoder/encoder for any specific codec. The common workflow would be to have a separate codec and pass what the codec gives to RFLV.
decode:
let stream = ...; // must implement WriteBytesExt/ReadBytesExt of byteorder
let tag = FlvTag::decode(&mut stream)?;
