Frage

Kürzlich habe ich den Live555 -Server -Quellcode von ihrer Website heruntergeladen. Ich habe versucht zu kompilieren und zu rennen testMPEG1or2AudioVideoStreamer.cpp Datei in der testProgs Verzeichnis. Ich habe das gesamte Projekt einschließlich der Testprogramme erfolgreich zusammengestellt. Dann leite ich die testMPEG1or2AudioVideoStreamer Testprogramm. Ich habe auch a platziert test.mpg Datei im aktuellen Verzeichnis im Sinne des Testprogramms. Nach dem Laufen bekam ich die folgende Ausgabe:

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.,

Dann kopiere und spiele ich die URL rtsp://192.168.2.22:5555/testStream Verwenden Sie VLC Media Player, aber VLC warten Sie einfach und stoppen Sie dann (auch mit Gnome Mplayer). Es wird kein Audio oder Video abgespielt. Jede Hilfe wird geschätzt, da ich nicht vorwärts gehen kann, ohne erfolgreich mit Live555 zu streamen. Hier ist der Code von testMPEG1or2AudioVideoStreamer.cpp. Kannst du mir sagen, was ich vermisse ...

Bearbeiten 2: Portprüfung

Ich habe Zenmap verwendet, um die Ports zu scannen, und es zeigt 5555 als TCP -Anschluss und als offen. Aber es zeigt die Anwendung als Freeciv, aber ich habe dieses Spiel nicht in meinem System installiert. Vielleicht ist es eine Vermutung von Zenmap. Ich betreibe Fedora 16 mit GNOME 3.2 auf meinem System.

War es hilfreich?

Lösung

Ich vermute, dass dies möglicherweise etwas mit der Verwendung einer nicht standardmäßigen Portnummer zu tun hat, aber ich kann mich irren. Der IANA-zugewiesene RTSP-Port beträgt 554 und 8554 als sekundäres IIRC.

Es sieht so aus, als hätten Sie den Live555 -Code auf dem Server geändert, um stattdessen 5555 zu verwenden. Sie wissen jedoch nicht, ob die Verwendung von Live555 durch VLC mit nicht standardmäßigen RTSP-Portnummern unterstützt wird. Ich nehme an, Sie könnten dies im VLC -Code nachsehen.

Dinge, die Sie versuchen können:

  • Verwenden Sie OpenRTSP -Arbeit mit dem URI
  • Verwenden Sie einen Paket -Sniffer, um zu sehen, was tatsächlich im Netzwerk passiert, dh, welche Ports verwendet werden.
  • Verwenden Sie den Standardport und prüfen Sie, ob dies funktioniert

Mit diesen Schritten können Sie dort eingrenzen, wo sich das Problem befindet.

Bearbeiten:

Aus den RTSP -COMMS können Sie feststellen, dass VLC versucht, eine Unicast -Sitzung zu erstellen. Der Server reagiert mit einer Multicast -Transportadresse. VLC spielt dann den Stream ab, erhält für 10s keine Daten und versucht dann, eine verschachtelte RTP -RTP -Sitzung zu starten, auf die der Server erneut mit einer Multicast -Adresse reagiert, und daher reagiert der RTSP -Server mit 461. Laut Live555:

testMpeg1or2audiovideostreamer liest eine MPEG-1- oder 2-Programmstromdatei (mit dem Namen "test.mpg"), extrahiert aus diesem Audio und einem Video-Elementarstream und streams diese unter Verwendung von RTP in die Multicast-Gruppe 239.255.42.42, Port 6666667777777777, Port 666666777, aus. (für den Audio -Stream) und 8888/8889 (für den Video -Stream). Dieses Programm verfügt auch über einen (optionalen) integrierten RTSP-Server.

Andere Tipps

Haben Sie mehr als eine Netzwerkschnittstelle? Der Verkehr kann die falsche Schnittstelle durchlaufen. Sie können Wireshark oder andere Paket -Sniffer verwenden, um dies zu überprüfen. Sollte dies der Fall sein, kann dieser Mail -Thread hilfreich sein:http://lists.live555.com/pipermail/live-devel/2007-may/006864.html

In meinem Fall funktionierte die Deaktivierung der virtuellen Maschine (in diesem Fall VirtualBox) Netzwerkadapter.
