mpeg-ps

MPEG-1/2 Program Stream parser — ISO/IEC 13818-1 (Rec. ITU-T H.222.0) §2.5.

Parses the .mpg/.vob framing that wraps PES packets: the pack header (42-bit SCR + program_mux_rate), the optional system header (rate/audio/video bounds + per-stream P-STD buffer bounds), and the program stream map (PSM).

#![no_std] + alloc; depends only on dvb-common and mpeg-pes.

Quick start

use mpeg_ps::PackHeader;
use dvb_common::Parse;

let bytes = [
    0x00, 0x00, 0x01, 0xBA,
    0x44, 0x00, 0x04, 0x00, 0x04, 0x01,
    0x40, 0x00, 0x03, 0x00,
];
let h = PackHeader::parse(&bytes).unwrap();
assert_eq!(h.program_mux_rate, 3);

use std::fs;
use mpeg_ps::program_stream;

let data = fs::read("tests/fixtures/ffmpeg-mpeg2-ps.mpg").unwrap();
let (packs, _) = program_stream::parse_all_packs(&data).unwrap();
println!("Found {} packs", packs.len());
