Hallo!
Hat von euch jemand eine Webcam und nutzt das Programm camE?
http://linuxbrit.co.uk/camE
Meine Logitech QuickcamExpress funktioniert hier unter Gentoo ganz gut unter dem device /dev/video0 (kann momentan bilder zwar nur als root auslesen (weil permission denied für normale user), aber das ist momentan noch nebensächlich)
Die Webcam ist direkt am Webserver angeschlossen. Es ist kein FTP Server installiert. Wie konfiguriere ich das Ding so, das mir camE alle 5 Sekunden ein Bild von der Webcam in ein bestimmtes Verzeichnis am Rechner stellt. Will das am besten via camE lösen, weil man hier schöne logfiles hat, und die Bilder mit Datum und Uhrzeit versehen werden und man schön Schriftart und Farbe ändern kann. Sprich das Tool scheint super zu sein, nur leider gibt es nirgenstwo eine Doku dazu :(
Vielleicht hat ja jemand von euch schon einmal damit gearbeitet und kann mir helfen?
Aufgabe ist klar?
Webcam an Webserver und soll n' Bild im 5 Sekunden Takt in ein Verzeichnis schieben und das Bild mit Datum und Uhrzeit versehen :)
Hier ist eine mitgelieferte Beispiel Konfigurationsdatei:

falls ihr Ahnung habt warum ich nur als root die Webcam auslesen kann, hier mal ein Auszug wenn ich als normaler user xawtv starten will :)
$ xawtv -c /dev/video0
This is xawtv-3.94, running on Linux/i686 (2.6.10-gentoo-r6)
/dev/video0 [v4l]: no overlay support
v4l-conf had some trouble, trying to continue anyway
v4l2: open /dev/video0: Keine Berechtigung
