dvb-pes

PES (Packetized Elementary Stream) depacketization + PTS/DTS — the sublayer between an MPEG-TS packet layer and an elementary-stream consumer. Per ISO/IEC 13818-1 (Rec. ITU-T H.222.0) §2.4.3.6 / §2.4.3.7.

#![no_std] (+ alloc), depends only on dvb-common, WASM-clean. Pairs with dvb-si for the TS/PSI layer:

TsPacket payload + payload_unit_start ──► dvb-pes ──► PesPacket { stream_id, pts, dts, payload }

Quickstart

use dvb_pes::{PesPacket, StreamId};

let bytes = [
    0x00, 0x00, 0x01, 0xE0, 0x00, 0x0A, 0x80, 0x80, 0x05,
    0x21, 0x00, 0x01, 0x00, 0x01, // PTS = 0
    0xAA, 0xBB,                   // ES payload
];
let pkt = PesPacket::parse(&bytes)?;
assert_eq!(pkt.stream_id, StreamId(0xE0));
assert!(pkt.stream_id.is_video());
assert_eq!(pkt.header.unwrap().pts.unwrap().ticks(), 0);
assert_eq!(pkt.payload, &[0xAA, 0xBB]);
# Ok::<(), dvb_pes::Error>(())

Features

Scope

In: PES packet header, stream_id, PES_packet_length (incl. unbounded video 0), the optional header flags, and PTS/DTS (33-bit @ 90 kHz). Out: elementary-stream codec bitstream parsing (the consumer's job); network transport (see dvb-stream).
