StuRa:Server/Streaming
potenzielle Software
ffserver
How do I make it work?
As a simple test, just run the following two command lines where
INPUTFILE is some file which you can decode with ffmpeg:
ffserver -f doc/ffserver.conf &
ffmpeg -i INPUTFILE http://localhost:8090/feed1.ffm

aus einem Hörsaal
Es gibt verschiedene Wege.
Wie gewohnt, kann WLAN verwendet werden. Bei der Bereitstellung von Streaming sollte wohl aber die "festest" mögliche Anbindung genutzt werden, wobei eigentlich LAN zu bevorzugen wäre. Bei WLAN an unserer Hochschule sollte eduroam verwendet werden. VPN/WEB fällt natürlich schon allein wegen der Begrenzung zur Notwendigkeit der erneuten Anmeldung nach einer bestimmten Dauer heraus.
Wenn LAN genutzt werden kann, was zu bevorzugen ist, muss wohl in den Hörsälen das sogenannte Hörsaalnetz genutzt. Um eine Verbindung zu allen anderen Rechner und dem Internet herstellen zu können, muss VPN für das Hörsaalnetz verwendet werden.
VPN für das Hörsaalnetz verwenden
- eigentlich siehe VPN
- Installieren von vpnc
sudo apt-get install vpncsudo apt-get install network-manager-vpnc
