Res iptv

Serijinis numeris yra parašytas ant IPTV BOX'o (dėžutės kurios pagalba žiūrite iptv per TV).

ARBA

Pažiūrėję srautą, turim gauti http user agent'o headerį t.y aprašą (tai yra iptv box'o serijinis numeris). Pagal jį ir vyksta visa http ir stream'o autorizacija. Taigi...

192.168.1.99 - iptv box'o ip

tcpdump -i eth1 -s 0 -A src host 192.168.1.99 and dst port 80

Arba jeigu nežinome tikslaus tvbox ip adreso tinkle, galime daryti taip

tcpdump -i eth1 -s 0 -A dst port 6081 -vvv -X

Gavus kažą panašaus į:

stb_xxxxxxxxxxxx

Naudodami šį gautą serijinį numerį galime užspoofinti user agentą ir gauti visą kanalų sąrašą

curl -A "USER_AGENTAS" -O http://archyvas.res.lt/playlist

Žiūrėti kiekvieną kanalą galima su vlc pagal jo m3u8 playlistą. t.y:

./vlc http://cache.res.lt:6081/hls001-live/lrt_tv.m3u8 :http-user-agent=USER_AGENTAS

Aišku tai labai nepatogu ir reikia tam pasidaryti grojaraštį:

FIXME

cat playlist |grep url_hls|sed -n 's!^.*>\(http[^^]*\)<.*!\1!p'|xargs wget --user-agent="USER_AGENTAS" -O playlistas.m3u

Arba paprasčiau:

cat playlist |grep url_hls|sed -n 's!^.*>\(http[^^]*\)<.*!\1!p' > play.m3u
./vlc play.m3u :http-user-agent=USER_AGENTAS

EPG Generavimas

php scriptas skirtas generuoti xml epg (angl. electronic programme guide) failus suprantamus daugelių iptv leistuvų ir media centrų, reikalinga tik pakeisti kintamejį $user_agent į jūsų box'o.

<?php
// Tool to generate compatible xml epg list based on RES IPTV json sources
// validation can be made with this tool: https://www.freeformatter.com/xml-validator-xsd.html
// script is very primitive as not error handling are made, please improve it by yourself
$user_agent = "user agentas"; // user agent used for auth with iptv servers
$write_to_xml = 1; // write static 'res-epg.xml' file
$loud = 0; // print messages can be used to load xml directly
$script_dir = dirname(__FILE__);

Paleisti php epg_gen.php, bus sugeneruotas res_epg.xml failas kurį galima naudoti bet kuriame iptv leistuve.. Patartina leisti kas 6val arba dar rečiau ir pahostinti kur nors leistuvui prieinamoje vietoje..
