Streamovani z webkamery po siti na serveru ( bez gui )

[kukuraj]

Zdravím vespolek, potřeboval bych radu. Mám webkameru připojenou k 12.04 server. Chtěl bych streamovat video na web nebo ukládat do souboru a nemůžu to rozchodit. Kamera se zdá funkční a podporovaná ( genius facecam 321 ID 0458:7089 ) příkaz dmesg:

 mohlo by vysvetliť   Unable to autolaunch a dbus-daemon without a $DISPLAY for X11
EDIT:
Ako náhradu by si mohol skúsiť Motion tu
na fóre sa to niekde preberalo v súvislosti s ip kamerou

[kukuraj]

Díky moc za rady a nasměrování. Nicméně to VLC se mi nějak nedařilo. Skončil jsem v bodě, kdy mě obraz z kamery zobrazovaly v terminálu ascii znaky a neustále nějaké problémy. Zkusil jsem ten ffmpeg, ten mě fungoval relativně hned. Nicméně dokážu ho dostat do stavu, kdy spustím server, dokážu z kamery nahrát .avi na disk, nicméně nedokážu nastreamovat na web .asf. Jdu zkoumat core dump protože mě to cely padne při spuštění výstupu kamery na http

Skús pozrieť sem FFMpeg and FFServer

Jak psal Dano V - motion je lepší  sám mám webku na tomto serveru a jsem spokojen . Jen si musíš trochu pohrát s configem
