DeadAir made a shortened copy of each episode with ffmpeg: as much disk again as the original, one pause length for everyone, and a minutes-long wait after the download. Seeking past silences instead was tried on an iPhone and left about 1.3 s of nothing at every cut (#178). Now it finds a file's silences once (silencedetect, plus ffprobe for each frame's byte position) and stores a plan for each pause a person can choose, 0.2 to 0.5 s: the cuts, and the frames kept as byte ranges of the original. /media/{id}/deadair.m3u8 hands this person's plan out as an HLS playlist of ranges of /media/{id}/deadair.mp3, the original. Tested on iOS Safari first (#180): no gap at the cuts, plays locked, seeks exactly, and needs no ID3 timestamp in front of each piece. Other browsers get hls.js (1.6.19, the light build), loaded only when needed. Not where canPlayType says it can play HLS: Chromium answers "maybe" and then fails on MP3 ranges with "stream parsing failed", so only Apple's browsers play the playlist themselves. The pause is per person and per show, on deadair_prefs.pause_ms, 0.3 s unless chosen; 0.2 s, what the copies left, made speech sound rushed. AAC in MP4 has no ranges a playlist can use, so only MP3 and ADTS AAC are shortened (the library is 803 MP3s and no .m4a). The copies, their table and #179's expiry go: the first start drops the table and deletes the files it names, only those named name.deadair.*. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
ipx
A self-hosted podcatcher for a household. It checks your feeds, downloads the episodes, and serves
a web UI modelled on the 2004 Mac app iPodderX, for any number of people sharing one copy of
the files. One Rust binary, ipx, is both the daemon and the command line.
It is a rewrite of ipodderx-core, the Python engine behind iPodderX (2004-2008, Ray Slakinski & August Trometer).
What it does
- The web UI. It has a toolbar, and a feed list that opens with the Directory, Currently Listening and All Subscriptions. Items sit in a sortable table with a Files pane, and there is a player bar. It comes in Dark, Light and Classic themes, and works on a phone.
- Several people, one copy. Each person has their own subscriptions and their own read, pinned and playback state. There is one file on disk per episode, however many people want it. People sign in with a password or through a proxy (Cloudflare Zero Trust or Authentik), and admins manage accounts and settings.
- Scanning. Feeds are checked on a schedule, globally or per feed, and a feed's own TTL is honoured. Keyword, explicit-content and media-type filters decide what is downloaded, with a limit on how many of a feed's newest episodes are downloaded.
- Downloads. Files come over HTTP or BitTorrent and are filed into a folder per feed. Retention deletes the oldest files to stay under a disk quota or an age limit, and never touches an item someone has pinned.
- OPML. You can import and export your own subscriptions. You can also subscribe to an OPML URL, which keeps a whole list in step as a folder.
Run it
With Docker:
docker build -t ipx .
docker compose up -d
docker-compose.yml is set up for the author's own server. Point its image and its three volumes
(/config, /data and /downloads) at yours first. The UI is on port 8099. BitTorrent uses 6881
over TCP and UDP. Files are written as PUID/PGID, 99:100 by default.
From source:
cargo build --release
./target/release/ipx daemon
The first start creates admin / ipodderx. Sign in at /login, then change it:
echo -n 'a good password' | ipx user passwd admin
The UI is plain HTTP, so put TLS in front of it if it is reachable from outside your network.

Tests
cargo test # the engine: parsing, filters, retention, schedules, SQL, per-user state
node tests/page-smoke.js # the page script loads without throwing
node tests/native-bridge.js # the page hands playback to a native shell
npx playwright test # a real browser against a real daemon on fixture feeds
npm install gets the test runner, and npx playwright install --with-deps chromium gets the
browser.
