Dotaz: RTSP stream z DVR ICR-H41

[Honzaa]

Dobry den vespolek, poridil jsem si zaznamove zarizeni ICR-H41 od firmy IdentVision. Problem je v tom, ze aplikace pro dalkovy pristup je pouze pro Windows. Pres Wine nejede. Zarizeni nasloucha na portech 554 a 23. Heslo do telnetu jsem nerozlouskl. Co vim o protokolu RTSP je, ze potrebuju znat cestu k souboru(m), kde najdu stream. Ale absolutne nemam poneti, jak ji zjistit. Zkousel jsem cesty od jinych DVR, ale bez uspechu. Nema nekdo zkusenosti s timto DVR ci nejaky napad, jak z toho vydolovat obraz? Dekuji za pripadne reakce..

Udelal jsem pokrok s timto dvr. Mam uz pristup do konzole. O vsechno se stara nejaky proces Sofia, pravdepodobne i o rtsp stream. Ale nastaveni to nikde nema.. Zachytavanim paketu pri prehravani videa v prohlizeci jsem zachytil tutu url: rtsp://192.168.35.19:554/user=admin&password=&channel=2&stream=0.sdp/trackID=3 RTSP/1.0
kdyz ji davam do vlc, hodi to chybu. Opet vypis z Wiresharku:
