💖 extract_a52 — the girlies are ripping A/52 audio out of MPEG streams 💖

okay so real talk: this is a page from the General Commands Manual, section 1, and the star of the show is extract_a52. she does exactly one thing and she does it well — she reaches into a MPEG stream and pulls out the ATSC A/52 audio like it's the last boba straw. no cap. 🧋✨

🌸 SYNOPSIS 🌸

extract_a52 [-h] [-s [track]] [-t pid] [file]

that's the whole vibe. one command, a couple of flags, maybe a file, and you're done. periodt. 💅

✨ DESCRIPTION ✨

extract_a52 extracts ATSC A/52 audio from a MPEG stream. that's it, that's the job, and she is so good at it. 🎀

and here's the cute part: if you don't hand her a file at all, input comes from stdin. so you can literally just pipe things into her and she'll happily slurp it up. main character energy fr fr. 🦋

💜 the options (there are only three, we love a low-maintenance queen)

  • -h — display help. that's it. she tells you how to use her and then she dips. 🙈
  • -s track — set the track number. the valid range is 0-7 or 0x80-0x87 — yes, both notations, she's flexible like that. 💫
  • -t pid — use the transport stream demultiplexer, with pid in the range 0x10-0x1ffe. hex only, bestie, that's the assignment. 🔥
⚠️ heads up: those ranges are exactly what she accepts — don't come at her with a track of 9 or a pid outside 0x10-0x1ffe and expect a happy ending. the manual says the range, so the range is the range. iykyk. 💀
