"""DD12Streams extractor — scrapes inline m3u8 URLs from per-channel pages.
|
||
|
|
|
||
|
|
Each DD12 sport page (`/nas`, `/f1`, `/sky`, etc.) renders an iframe to
|
||
|
|
`/<channel>c1` which 302-redirects to `/new-<channel>/jwplayer`. That
|
||
|
|
page contains a JW Player setup with the m3u8 URL hard-coded inline:
|
||
|
|
|
||
|
|
playerInstance.setup({
|
||
|
|
file: "https://...b-cdn.net/.../master.m3u8",
|
||
|
|
...
|
||
|
|
});
|
||
|
|
|
||
|
|
The JW Player runtime fails in our cluster (same fingerprint trap as
|
||
|
|
hmembeds), but we don't need it — the file URL is in the HTML and any
|
||
|
|
browser with H.264 codecs can play it directly via hls.js.
|
||
|
|
|
||
|
|
Channel discovery: probe a known list. New ones can be added by checking
|
||
|
|
DD12's own homepage / nav.
