Impossibile eseguire lo streaming con il server Live555 - Esempio non funzionante

Question

Recentemente ho scaricato il codice sorgente del server Live555 dal proprio sito. Ho provato a compilare ed eseguire il file testMPEG1or2AudioVideoStreamer.cpp nella directory testProgs. Ho compilato l'intero progetto compresi i programmi di test con successo. Quindi eseguo il programma di test testMPEG1or2AudioVideoStreamer. Ho anche inserito un file test.mpg nella directory corrente come definito nel programma di test. Dopo l'esecuzione ho ricevuto il seguente output:

Play this stream using the URL "rtsp://192.168.2.22:5555/testStream" 
Beginning streaming... 
Beginning to read from file... 
...done reading from file 
Beginning to read from file... 
...done reading from file 
etc., 

Poi ho copiare e riprodurre l'URL rtsp://192.168.2.22:5555/testStream utilizzando VLC media player, ma VLC solo aspettare qualche tempo e poi fermarsi (stesso con Gnome MPlayer anche). Non riproduce audio o video. Qualsiasi aiuto è apprezzato in quanto non posso andare avanti senza lo streaming con successo utilizzando Live555. Ecco il codice di testMPEG1or2AudioVideoStreamer.cpp. Mi puoi dire quello che mi manca ...

EDIT 2: controllo porta

ho usato Zenmap di scansione delle porte e mostra 5555 come porta TCP e come aperta. Ma mostra l'applicazione come freeciv, ma non ho installato quel gioco sul mio sistema. Potrebbe essere una supposizione di Zenmap. Sto usando Fedora 16 con gnome 3.2 sul mio sistema.

Answer 1

ho il sospetto che questo potrebbe avere qualcosa fare con l'uso di un numero di porta non standard, ma potrei essere w rong. La porta RTSP assegnata a IANA è 554 e 8554 come IIRC secondario.

Sembra che tu abbia modificato il codice live555 sul server per utilizzare 5555. Tuttavia non si sa se l'utilizzo di Live555 da parte di VLC supporti l'utilizzo di numeri di porta RTSP non standard. Suppongo che potresti vedere questo nel codice VLC.

cose che potete provare:

• uso lavoro openRTSP con l'URI
• utilizzare uno sniffer di pacchetti per vedere che cosa sta realmente accadendo sulla rete vale a dire quali porte vengono utilizzati.
• utilizzare la porta standard e vedere se funziona

Questi passaggi vi permetterà di restringere dove è il problema.

Edit:

Dalle comunicazioni RTSP si può vedere che VLC sta cercando di creare una sessione unicast, il server risponde con un indirizzo di trasporto multicast.VLC gioca poi il flusso, non riceve dati per 10s e quindi tenta di avviare un RTP over RTSP sessione interleaved a cui il server risponde di nuovo con un indirizzo multicast e quindi il server RTSP risponde con 461. Secondo LIVE555:

testMPEG1or2AudioVideoStreamer legge un file di flusso di programma MPEG-1 o 2 (denominato "test.mpg"), estrae da questo un flusso elementare audio e video e li trasmette, utilizzando RTP, al gruppo multicast 239.255.42.42, porta 6666/6667 (per lo streaming audio) e 8888/8889 (per lo streaming video). Questo programma ha anche un server RTSP (opzionale) integrato.

Answer 2

Avete più di una interfaccia di rete? Il traffico potrebbe passare attraverso l'interfaccia sbagliata. Potresti usare Wireshark o altri sniffer di pacchetti per verificarlo. Se questo dovesse essere il caso, questo thread di posta può essere utile: http://lists.live555.com/pipermail/live-devel/2007-May/006864.html

Answer 3

Nel mio caso la disattivazione macchina virtuale (VirtualBox in questo caso) le schede di rete hanno lavorato.
