User asked to broaden the source pipeline so f1-stream can find F1 (and
adjacent motorsport) streams from Sky Sports / DAZN / Reddit / etc.,
using the in-cluster chrome-service headed browser where needed. Four
changes:
1. **streamed.py**: BASE_URL streamed.su → streamed.pk. The .su domain
stopped serving the API host in 2026 (only the marketing page is
left); .pk hosts the JSON API now. Adds 3 events/round (currently
all routed through embedsports.top — see #2 caveat).
2. **chrome_browser.py** (new): generic chrome-service-driven extractor.
Connects to the existing chrome-service WS (CHROME_WS_URL +
CHROME_WS_TOKEN env), navigates a list of TARGETS, captures any HLS
playlist URL the page fetches at runtime, returns one ExtractedStream
per discovery. Uses the same stealth init script as the verifier so
anti-bot checks don't trip the page. Handles iframes (DD12-style
/nas → /new-nas/jwplayer) and probes child-frame <video>/source
elements after settle. Caveat: most aggregator sites (pooembed,
embedsports, hmembeds, even DD12's JW Player path) use a broken
runtime decoder that produces no m3u8 in our environment, so the
TARGETS list is currently 0-yielding; the framework is the
contribution and concrete sites can be added as they're discovered.
3. **subreddit.py** (new): scans r/MotorsportsReplays, r/motorsports,
r/formula1, r/motogp via the public old.reddit.com JSON API for
posts whose flair/title indicates a live stream. Discovered URLs
are returned as embed-type streams; the verifier visits each via
chrome-service to confirm playability. Note: Reddit currently HTTP
403's our cluster outbound IP for anonymous JSON requests; the
extractor returns 0 in that state and logs a debug message. Will
work from any IP Reddit isn't blocking.
4. **dd12.py** (new): inline-HTML scraper for DD12Streams. The site
embeds `playerInstance.setup({file: "..."})` directly in HTML — no
JS decoder needed. Currently surfaces NASCAR Cup Series 24/7 (clean
BunnyCDN-hosted HLS at w9329432hnf3h34.b-cdn.net/pdfs/master.m3u8);
add new `(path, label, title)` tuples to CHANNELS as DD12 expands.
Result: /streams now shows 2 verified live streams (Rally TV via
pitsport + DD12 NASCAR Cup 24/7). When the next F1 weekend (Canadian
GP, May 22-24) goes live, pitsport will surface F1 sessions
automatically via the existing pushembdz path.
