Slackware: webcam
Qualcuno saprebbe dirmi come far funzionare la webcam?? è una creative webcam nx
Ho provato a seguire questa guida http://www.slackware-italia.com/articoli.php?IDART=25 ho ricompilato il kernel (2.6.0) con supporto a hotplug, pcia,video4linux, vari modelli di webcam(come moduli), supporto usb, ed installato correttamente gnomemeeting ma c'è qualcosa che non va xchè mi rimanda questo errore: Error while opening video device /dev/video1 The chosen Video Image will be transmitted during calls. If you didn't choose any image, then the default GnomeMeeting logo will be transmitted. Notice that you can always transmit a given image or the GnomeMeeting logo by choosing "Picture" as video device. There was an error while opening the device. Please check your permissions and make sure that the appropriate driver is loaded. Ho cercato in rete ma non riesco a capire cosa sbaglio o dimentico, o addirittura se la mia webcam è supportata o meno... Qualcuno saprebbe spiegarmi come devo procedere, e cosa serve esattamente per il funzionamento? Grazie |

/dev/video1 è il _secondo_ dispositivo video, se non ne hai altri devi usare /dev/video0.
Cmq puoi controllare con dmesg cosa succede, se il modulo di gestione viene caricato correttamente, ecc.

Probabilmente non hai i permessi per aprire /dev/video1
Prova a vedere se funziona da root, se da li va vuol dire che devi modificare i permessi di /dev/video1 in modo che sia accessibile anche dagli utenti non root. Meglio ancora sarebbe assegnare /dev/video1 ad un gruppo (per esempio al gruppo "video") e aggiungere gli utenti a cui intendi concedere l'utilizzo della webcam al medesimo gruppo. Cmq per ora prova ad usare gnomemeeting da root e vedi se ti funziona la webcam

Il tuo dispositivo ha l'usb id 041e:401c, che - da quello che vedo nei sorgenti del kernel 2.6.1, in particolare nel file pwc-if.c - non è supportato. Della Creative sono supportate le webcam con usb id pari a 041e:400c e 041e:4011, relativo sempre a webcam simili alla tua (ma non necessariamente compatibili!), dal driver Philips pwc (evidentemente la Creative usa chip Philips). Se vuoi fare una prova alquanto disperata (ma a volte la disperazione fa miracoli), prova ad applicare la patch che allego. Ricompila e reinstalla includendo il modulo pwc per webcam Philips, vediamo che succede. Non ti aspettare nulla, però...

Non funzia, grazie comunque della disponibilità!
purtroppo ho trovato questo sconfortante link http://www.qbik.ch/usb/devices/searc...php?pattern=nx faccio qualche altra prova, ma mi sa che dovrò aspettare il supporto (chissà quando!) |
