Re-check 2026-06-25 across the full id range confirmed both PlayTube tubes
serve only the fixed `/upload/videos/video_down.mp4` "server down" stub, never
a real file: hqfap 0/80 real (79 stub, 1 none), 4k69 0/40 real (38 stub, 2
none). Both were disabled 2026-06-22; CDN never came back, so removing entirely
(mirrors the pornhub/redtube/0dayxx/pornditt/pornhat removals).
Removed the extractor registry entries (hqfapcom, 4k69com) + module files and
the browse scrapers + imports. Prod DB data deleted separately (28,398
solo-orphan scenes + 46,196 playback_sources). `_playtube.py` kept: superporn
and neporn still use its JSON-LD helpers.

_embed_iframe returned xtremestream's player endpoint (player/xs1.php?data=) labeled
type=mp4, but it's an IP-bound JS player page (403 cross-IP), not a real file — the
native player loaded it forever ("perverzija nie działa" / "loading w nieskończoność").
Added xtremestream.* to _IP_BOUND_CDN_RE so Stage 1 skips it and falls through to the
hoster fallback: the phone WebView loads the index.php player with its residential IP
and the stream plays in-session.

Three orphan-factory tubes (0–0.2% canonical match — auto-screenshot thumbs and
slug titles that never match TPDB/StashDB) — to be replaced by better sources.
Removed scrapers (files + imports), extractors (registry + modules), the pornhat
entry from tag-enrichment priority lists and the 0dayxx display override, and purged
the DB (19,003 playback_sources + 9,904 solo-orphan scenes; shared mirror scenes keep
their other sources). The pornhat-based enrich_studio endpoint stays as a graceful
no-op (no pornhat sources → returns no studio).

Both scrapers were disabled since 2026-05-12 (~0.4% canonical match — mostly short
amateur clips that never match studio content); their data sat frozen. Removed for
good: deleted the extractor registry entries, scraper files and imports, dropped them
from the tag-enrichment priority lists, and purged the DB (17,906 playback_sources +
122 scenes that had no other source; mirror scenes shared with other tubes just lost
the ph/rt link).

hqfap migrated its JSON-LD contentUrl (and the *.workers.dev mirror) to /upload/videos/video_down.mp4, which serves a FIXED ~3.04MB file for EVERY scene regardless of declared length (verified 5/5 scenes at 14-47min all = 3.04MB, 2026-06-21). It is a placeholder/'server down' clip, not the content — the browser's own player streamed the same stub via MediaSource. We were handing users that 3MB stub (reports c382d441/ef10b946). Now reject the video_down.mp4 contentUrl and return no source, so scenes fall through to other sources or show no playback instead of a fake clip. Real older scenes (cdnde.com / okcdn.ru direct mp4) still resolve. This also makes the proxy-fallback question moot — there is no source to proxy.

Reverse-engineered the migrated 4k69 player: jwplayer now serves OK.ru CDN (okcdn.ru)
mp4s. The static page (SSR behind Cloudflare, fetched via proxy) carries "file"+"label"
pairs for every quality. okcdn's srcIp param is NOT enforced (cross-IP test 2026-06-14:
206 video/mp4 from a residential IP != srcIp), so the URL plays from any IP. Parse the
okcdn sources server-side and return them mobile_direct_ok — the phone plays the direct
video, no WebView, no VAST preroll, no age-gate, zero VPS proxy. Skips 4K/2K. Reverts
the brief _vps_blocked_fallback routing (WebView grabbed the preroll ad, not content).
Verified on emulator: native player streams the actual scene (report 5de3fbc5).

4k69 swapped its player from get_file (4kporno.xxx) to jwplayer + okcdn.ru, whose token
carries srcIp= (IP-bound); the site is also behind Cloudflare (VPS fetch only via proxy).
The native get_file extractor matched nothing and returned None, surfacing as a "host
problem" error even though the video plays fine (report 5de3fbc5). Switch 4k69com to
_vps_blocked_fallback: the on-device WebView (residential IP) clears Cloudflare, the
okcdn token binds to the phone IP, and INJECTED_JS hands the jwplayer source to ExoPlayer.
fourk69.extract stays in the module in case the site reverts to get_file.

Porntrex soft-deletes: a removed video returns HTTP 200 with a "this video was deleted"
message instead of a player, so extract returned [] (transient) and the source was never
marked dead, leaving users on a permanently broken link (report 75dbf53e). Match the
deletion message and raise HosterDead so resolve marks the source dead.

It is an ISP proxy (static ISP IPs, flat billing), not residential —
so HTML-ingest bandwidth is free and the full deep-crawl is fine.

superporn hard-blocks the VPS IP with Cloudflare 403 on every TLS
impersonation, so HTML ingest routes through Bright Data residential
(BRIGHTDATA_PROXY_URL, parsed in config). First scraper to use a proxy:
optional _proxy on the browse base, threaded into browser_get.
JSON-LD VideoObject (title/desc/uploadDate/thumb/duration) + pornstar
and category chips; superporn double-encodes HTML entities so titles
are unescaped twice. Thumbnails fetch fine from the VPS (no proxy).
Playback stays off-proxy: the <source> mp4 token is IP-bound to the
fetcher, so resolve is phone-side via WebView (extractor superporncom
-> _vps_blocked_fallback), same as porndoe.

4k69.com (~65k scenes): same PlayTube CMS as hqfap - common logic moved
to _playtube.py (sitemap catalog, JSON-LD, pills). Studio classified by
matching category pills against the studios index page. Streams are
get_file (fullmovies family) returned unresolved with mobile_direct,
2160p skipped.
neporn.com: KVS engine, latest-updates listing, JSON-LD + video:duration
meta, performers from models links with flashvars video_tags fallback
for fresh uploads. Resolve via _kvs; final URL portable cross-IP.
superporn.com rejected: Cloudflare 403 from VPS on all TLS impersonations.

PlayTube CMS. Sitemap-based pagination (listing has no GET paging),
JSON-LD VideoObject metadata, pornstar/category pills, " Clips"
categories mapped to studio. Direct mp4 (cdnde.com/okcdn.ru), tokens

xhamster: move from WebView fallback to server-side native HLS. The scene page
is fetchable server-side and the xhcdn master m3u8 (variants + segments) is
time-bound, not IP-bound (verified cross-IP), so mobile plays the HLS direct
with zero proxy bandwidth. New tubes/xhamster.py pulls the master m3u8 from
SSR HTML and returns type='m3u8' mobile_direct; registry remaps xhamstercom
off _vps_blocked_fallback.
hqporner: add flyflv to the player-iframe host whitelist. hqporner rotated
some players to flyflv.com; the CDN host was already whitelisted but the iframe
host was not, so those scenes returned no stream.

Chrome-DevTools investigation of bug-report 827a50a1 (sxyland "long loading,
then webview, no autoplay") showed sxyland embeds playmogo.com/e/<id> — a
DoodStream clone (doodcdn.io infra, pass_md5 protocol, get_slides) behind an
INVISIBLE Cloudflare Turnstile (not an interactive CAPTCHA; auto-passes in a
real browser/WebView from a residential IP). The sxyland page itself is NOT
Turnstile-gated — VPS curl pulls the playmogo iframe URL straight from the HTML.
sxylandcom was wired to _vps_blocked_fallback → phone loaded the entire sxyland
page in WebView (ads, click-to-play, no autoplay = the reported symptom), and the
playmogo embed never reached the phone's dood resolver. _embed_iframe (which
already lists sxyland in its docstring) extracts the playmogo embed and emits it
as type='hoster' → PlayerScreen routes playmogo URLs to doodstream.ts (resolveDoodStream),
which resolves phone-side (phone IP passes invisible Turnstile) → direct mp4 → autoplay.
Mobile unchanged (hoster→dood path already exists for xmoviesforyou/siska). Backend-only.

Two bug-report fixes (2026-06-07):
- sxyprn returns HTTP 200 "Post Not Found" for deleted posts (soft-404), so the
extractor returned None → resolve treated it as transient and never marked the
source dead, leaving a dead link offered forever. Now raise HosterDead on the
marker so resolve marks it dead.
- Scene playback sources were ordered alphabetically by origin, so a WebView-
fallback hoster (fpoxxx, IP-bound + ad-heavy) ranked above a working native
source (freshporno) on the same scene. Add is_vps_blocked_fallback() and sort
native-resolve origins ahead of WebView-fallback ones.
Verified on prod: sxyprn dead URL → HosterDead; scene sources reorder
freshpornoorg before fpoxxx.

User: "hdporngg loading forever". DevTools + cross-IP investigation (not guessing):
- site is alive (sample scenes 200; the one earlier 404 was a single removed video,
not the site — my earlier "site dead" was a hasty generalization).
- both are the same platform (<source src=.../get_file/8512/...mp4>), no function/0.
- the get_file 302 is fast (~100ms) but the 2160p/4K source on fpvcdn.com TIMES OUT
(~30s); 720p/480p resolve in ~1s. The player loading 4K first = the "loading forever".
- the final fpvcdn URL embeds the requester IP (ip=<fetcher>) -> IP-bound to whoever
resolves it; BUT the get_file itself is stateless (fresh session works) and valid >=90s,
and binds fpvcdn to the fetcher. So a VPS resolve would bind to the VPS IP (mobile 403),
but returning the get_file URL UNRESOLVED lets the phone follow the 302 itself ->
fpvcdn binds to the phone IP -> plays.
Fix: new _source_getfile resolver returns get_file URLs as mobile_direct (skip 4K),
phone resolves the 302 in-session. Native, multi-quality, no WebView, no proxy.
Replaces fullmovies' old force_proxy+4K extractor and the WebView fallback for both.
Backend-verified: resolve -> 720/480 mobile_direct, get_file fresh fetch -> 206. Pending
on-device confirmation (emulator unstable; same mechanism as porn00/freshporno which work).
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Same proper re-investigation as freshporno (DevTools + Bright Data residential
cross-IP + curl_cffi browser TLS). porn00's final CDN fe.porn00.org/...?token=&expires=
is PORTABLE cross-IP (token resolved from one residential IP replays 206 from a
different Bright Data residential IP) and only rejects non-browser TLS (plain curl
403, curl_cffi chrome 206). In #20 I tested the final URL with a standalone plain
curl, got 403, wrongly concluded "IP-bound" and left it on WebView (and before that
it used force_proxy, which violated the no-proxy stance).
porn00 flashvars are plain get_file (already decoded, no function/0 prefix), so
extend _kvs._URL_RE to match both forms — real_url passes plain URLs through
unchanged, _resolve_get_file follows the 302 in-session. porn00.py becomes a thin
_kvs wrapper. Verified no regression for the function/0 tubes (yespornvip/pornditt/
freshporno still resolve 3x mp4). Result: porn00 native multi-quality, mobile_direct,
zero proxy/WebView.
fpoxxx and pornxp were re-tested the same way and ARE genuinely IP-bound (403 from a
different residential IP — their token binds to the resolver IP), so they correctly
stay on the WebView fallback.

Re-investigated with the proper method (Chrome DevTools network capture + cross-IP
test via Bright Data residential proxy + curl_cffi browser-TLS) instead of guessing.
freshporno's real flow is get_file -> 302 -> cdn4.freshporno.org/remote_control.php
-> 206 video/mp4. The CDN URL is PORTABLE cross-IP (a token generated from one
residential IP replays fine from the VPS and from a different Bright Data residential
IP), it only rejects non-browser TLS fingerprints (plain curl -> 000, curl_cffi
chrome / ExoPlayer -> 206).
In #20 I tested the final URL with a standalone plain curl, got 000, and wrongly
concluded "unreachable from residential" -> kept it on the WebView fallback, which
barely worked (ad-heavy page, flaky). That false negative is the regression the user
reported. freshporno is function/0 KVS, so _kvs.resolve_kvs (which uses curl_cffi
chrome) already decodes + resolves it to a portable mp4 — switch to backend resolve
like yespornvip/pornditt: native, multi-quality, no proxy, no WebView.
Verified: backend resolve returns 3x mp4 (1080/720/480, mobile_direct) + cdn 206;
user confirmed native playback on device.

Bug 19866e9e ("problem z oboma hosterami"): a scene whose only two sources were
fullmovies.xxx and hdporn.gg wouldn't play at all — neither had an entry in the
extractor registry, so try_extract returned None ("no stream"). fullmovies.xxx
serves a <source ...get_file...mp4> but the get_file CDN times out from the VPS
(unreachable, like freshporno), so backend resolve isn't viable; hdporn.gg sample
pages 404. Route both through the WebView fallback so the phone (residential IP)
loads the page and plays / the injected-JS scrape can grab the URL — strictly
better than no playback path. Surfaced by the hoster sweep + this bug report.

Hoster sweep (2026-06-02) found pornhub resolving to 0 sources: yt-dlp (current,
2026.03.17) gets HTTP 403 fetching the watch page from the Hetzner VPS, while the
other yt-dlp tubes (xvideos/xnxx/youporn/redtube) still work — so it's a
Pornhub-specific block of the server IP, not a yt-dlp regression. Route pornhub
through the WebView fallback so it plays from the phone's residential IP, same as
xhamster. 7.3k scenes affected.

Bug 6ec1960e: yespornvip "resolving forever". yesporn.vip moved to a
cdn4/remote_control.php CDN (still portable cross-IP — verified 206 from a
residential IP, so backend resolve stays correct). But when a video is removed
from the CDN the page still exists and each get_file 302-follow STALLS to the
full timeout. With the resolve timeout (60s) applied per quality variant, a dead
scene hung 3x60 = 180s and returned nothing -> the mobile resolve spinner never
ended.
Fix: a dedicated low get_file timeout (10s, separate from the page-fetch
timeout) and an early-break once 2 variants fail with no result so far (the
scene is dead on the CDN — no point waiting for the third). Dead scene now
resolves to None in ~20s instead of 180s; a live scene is unaffected (~0.8s,
3 sources). Applies to all KVS tubes (yespornvip + pornditt).
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Re-checked whether these four KVS tubes could move to server-side resolve
like yespornvip/pornditt/porntrex. All four are reachable from the backend,
but cross-IP testing showed their final CDN URLs are IP-bound to the
resolving host (403 / connection refused from a different IP; fpo.xxx even
embeds the resolver IP in its acctoken). Unlike the portable cdn5/twa CDNs,
backend resolve cannot produce a mobile-playable URL here without a proxy,
which is out of scope for the public app.
- porn00: was using force_proxy resolve (violated the no-proxy stance);
switched to the WebView fallback like its siblings. The ad exposure that
originally motivated the proxy path is mitigated by the recent ad-filter
work (AD_HOSTS + cover overlay + injected-JS ad-CDN skipping).
- freshporno/pornxp/fpoxxx already on WebView fallback; comments updated
with the cross-IP findings so this isn't re-investigated.
- Dropped the now-unused tube extractor imports (F401).

pornditt is the same kt_player KVS engine as yespornvip: flashvars carry
function/0/-obfuscated get_file urls + license_code, and the VPS reaches it
(HTTP 200). It was on _vps_blocked_fallback (WebView), where the scrape grabbed
the VAST preroll ad (trafostatic) instead of content (user bug "pornditt łapie
reklamę zamiast video").
Extracted the verified yespornvip logic into app/extractors/tubes/_kvs.py
(resolve_kvs: fetch page → decode function/0 get_file via kt_player algo → follow
302 in-session → portable CDN, multi-quality). yespornvip.py and new pornditt.py
are now thin wrappers. Registry: porndittcom _vps_blocked_fallback → pornditt.extract.
Verified on prod: pornditt → 720p/480p on twa.tgprn.com (portable, fresh-session
206 video/mp4); yespornvip still → 1080/720/480p on cdn5 (refactor intact).
Backend-only, no OTA — mobile plays mp4+mobile_direct_ok natively with quality
picker, zero WebView/ads.
Note: a real-browser residential load shows MEDIA_ERR on the content (the page's
own player flow / ad gating); server-side decode+follow sidesteps the player
entirely, which is why it resolves cleanly. The original bug scene (40f118e1) has
its video deleted on pornditt — verified on a live scene (156091).
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
yespornvip was on the WebView fallback, which loaded the ad-heavy host page; the
INJECTED_JS scrape grabbed the preroll ad video (bkcdn.net, ~30s) instead of the
content, so the native player showed a 30s ad. The get_file content url is also
session/cookie-bound (410 for a cookieless ExoPlayer request).
Key finding: the VPS now reaches yesporn.vip (HTTP 200 — unblocked, same as
porntrex got 2026-05-22), so we can resolve server-side like porntrex instead of
relying on the browser. KVS flashvars carry function/0/-obfuscated get_file urls +
license_code; decode the hash with the kt_player algorithm (yt-dlp KVS algo,
verified to reproduce kt_player's output), then follow each quality's get_file 302
in the same curl_cffi session → final cdn5 url. That url is time-bound signed but
NOT IP/cookie-bound — verified portable cross-IP (VPS-resolved url fetched from a
different IP → 206 video/mp4).
New app/extractors/tubes/yespornvip.py returns 480p/720p/1080p portable CDN urls;
registry switched from _vps_blocked_fallback → yespornvip.extract. Mobile plays
direct natively with a working quality picker — zero WebView, zero ads, zero proxy.
Verified on prod (3 cdn5 sources) and emulator (quality picker → 1080p native
decode at 1920px, no WebView, no ad). Backend-only; no OTA needed.

User bug: porntrex plays slowly, no quality picker, reload flicker — suspected
VPS proxy. Root cause: porntrex KVS get_file tokens are cookie/session-bound, not
just time-bound as previously assumed. The extractor handed mobile the raw
get_file url; ExoPlayer's cookieless request → 410 → mobile fell back to the VPS
proxy (slow + nav.replace flicker).
Verified: following get_file in the same curl_cffi session that fetched the page
→ 200 (streams video); a fresh session → 410. The final CDN url after the 302
(cdn.pcdn.cloudswitches.com/...?expires=&md5=) is portable — fresh session → 206.
Fix: extract() now uses one curl_cffi Session for page + get_file, follows each
quality's 302 (stream + Range, no body download) and returns the resolved CDN url.
Mobile plays direct, multi-quality picker works, zero proxy bandwidth. Falls back
to the raw get_file url if a resolve fails. Verified on prod: both 720p/480p now
resolve to cloudswitches CDN.

Previous attempts to extract direct stream URL from yesporn.vip flashvars both
turned out broken (verified 2026-05-30):
- video_url ('/get_file/7/'): requires PHPSESSID cookie from embed page session;
standalone mobile fetch returns 404
- event_reporting2 ('/get_file/1/'): returns HTTP 200 but Content-Type: image/gif
(1x1 analytics tracker pixel, not video)
Switch yespornvip -> _vps_blocked_fallback.extract. Mobile loads embed in WebView
with phone IP; kt_player JS decodes URL inside browser context (cookies + session
set properly); INJECTED_JS scrapes <video>.src and posts to ExoPlayer. UX flicker
(page renders before video) is the trade-off but aligns with no-video-proxy policy
(public-app bandwidth/anonymity priority).
