RussianDomanda
Recentemente ho scaricato il codice sorgente del server LIVE555 dal loro sito. Ho provato a compilare ed eseguire il file nella directory testMPEG1or2AudioVideoStreamer.cpp testProgs. Ho compilato l'intero progetto compresi i programmi di test con successo. Poi ho eseguito il programma di test testMPEG1or2AudioVideoStreamer. Ho anche messo 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 copio e suono il rtsp://192.168.2.22:5555/testStream URL utilizzando VLC media player, ma VLC solo aspettare qualche tempo e poi smetto (stesso con Gnome MPlayer anche). Essa non gioca alcun audio o video. Ogni aiuto è apprezzato come io 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: di controllo porta
Ho usato Zenmap di scansione delle porte, e si vede 5555 come una porta TCP e più aperto. Ma mostra l'applicazione come Freeciv, ma non ho installato quella partita sul mio sistema. Forse è una congettura da Zenmap. Sono in esecuzione Fedora 16 con Gnome 3.2 sul mio sistema.

Soluzione
Ho il sospetto che questo potrebbe avere qualcosa a che fare con l'uso di un numero di porta non standard, ma potrei sbagliarmi. La porta RTSP IANA-assegnato è 554, e 8554 come IIRC secondaria.
Sembra che tu modifed il codice LIVE555 sul server da utilizzare al posto 5555. Tuttavia non si sa se l'utilizzo di VLC di supporti LIVE555 utilizzando numeri di porta RTSP non standard. Suppongo che si poteva guardare questo in su nel codice di VLC.
Cose che si possono provare:
- uso openRTSP lavoro con l'URI
- utilizzare una ventosa di pacchetto di vedere ciò che è effettivamente accadendo sulla rete cioè quali porte vengono utilizzati.
- utilizzare la porta standard e vedere se funziona
Questi passaggi vi permetterà di restringere dove il problema è.
Modifica:
Dal RTSP Comms si può vedere che VLC sta cercando di creare una sessione unicast, le risponde server con un indirizzo di trasporto multicast. VLC gioca poi il flusso, non riceve dati per 10 e poi i tentativi di avviare un RTP interlacciato sopra sessione RTSP a cui il server risponde di nuovo con un indirizzo multicast e quindi le risponde server RTSP con 461. Secondo LIVE555:
testMPEG1or2AudioVideoStreamer legge un MPEG-1 o un file di 2 Program Stream (denominato "test.mpg"), estratti da questo un audio e un video Elementary Stream, e ruscelli questi, utilizzando l'RTP, al gruppo multicast 239.255.42.42, porto 6666/6667 (per il flusso audio) e 8888/8889 (per il flusso video). Questo programma ha anche un (opzionale) built-in server RTSP.
Altri suggerimenti
Avete più di un'interfaccia di rete? Il traffico può essere passare attraverso l'interfaccia sbagliata. Si potrebbe utilizzare Wireshark o altro packet sniffer per controllare che. Se questo dovesse essere il caso, questo thread di posta può essere utile: http://lists.live555.com/pipermail/live-devel /2007-May/006864.html
Nel mio caso la disattivazione macchina virtuale (VirtualBox in questo caso) le schede di rete hanno lavorato.
