Recuperare lo stream da una ip camera

[davidee]

Ciao a tutti.

Ho un problema, sto implementando un sistema di videosorveglianza, attualmente possiedo 3 ip camera.
Per le prime 2 tutto ok, riesco a recuperare lo stream per instradarlo in un software di videosorveglianza su pc, la terza mi sta facendo impazzire.
La comprai mesi fa su shopto.it, il nome della cam e' albion iph 237.
Inutile dire che non c'e' traccia in rete ne della casa produttrice ne del modello.
Una cam made in china.Dunque, se apro l'ip della cam con firefox o explorer, previa installazione di alcune ocx, l'immagine si vede senza problemi.
Non si riesce a vedere lo streaming con vlc o software di videosorveglianza in nessuna maniera.
La cam supporta il multicast e il multijpeg, nel cd allegato c'e' la cartella sdk con alcune indicazioni di programmazione.Esempio di cosa dice il manuale per recuperare lo stream:


CTransferSession encapuslates the detail about requesting audio/video, receiving, statistics and record, etc. It's sub-class CChannelSession adds decoding. Following code illustrate how to create a session and start it.
CChannelSession *pSess;
pSess = new CChannelSession(
pConn, //A pointer to connection object
0, //Video channel
pConn->iPort, //UDP port
);
pSess->SetTransportType(TRANSPORT_TCP); //Transport type to use. TCP is the default
pSess->AddVideoWnd(hWnd); //Add a output window of decoding
pSess->StartSession(); //Start the session
If m_bPlayAudioif TRUE when StartSession is called, audio data is also requested. You can use StartAudioReceiving()/StopAudioReceiving() to control audio data

When use CChannelSession, if output windows is added(through AddVideoWnd/SetVideoWnd), StartSession starts video decoding. UseStartAudioDecoding()/StopAudioDecoding() to control decoding of audio data.



Suppongo sia una routine in java, attualmente non voglio una routine per recuperare lo stream, mi servirebbe unicamente un qualcosa tipo http://ip_camera/mjpeg.cgi o qualcosa di similare
Con vlc se provo a mettere indirizzo della cam mi da impossibile connettersi perche' ovviamente la cam prova ad aprire una pagina html con lo stream inserito, idem per il multicast.
Questo e' l'html della pagina che apre l'ip cam con lo stream al suo interno:

In sintesi, ci sto sbattendo la testa contro da 2 giorni, qualche anima pia saprebbe come recuperare questo benedetto percorso all'interno della cam (non l'ip che conosco benissimo) per lo stream in mjpeg o h264?

[davidee]

Nessuna anima pia?

[Apocalysse]

Visto che non mi hai dato feedback per quello che ti avevo detto di fare su NGI, fai cosi
Firefox => installi LIVE HTTP HEADERS => Apri LIVE HTTP HEADERS => Apri lo stream della videocamera da Firefox
Guardi le voci GET a cosa puntano, una di quelle punta al filmato, a quel punto lo dai in pasto a VLC

[davidee]

Ciao Apo, ti ho risposto di la, non riesco cmq a recuperare il file nella camera che produce lo stream.
Oggi provo a fare quello che suggerisci con FF e vediamo un po se se ne viene a capo.
Dankescen!
