Kopete/Supporto webcam
Questa guida ha lo scopo di mostrare i principali passaggi necessari per utilizzare tua webcam con Kopete. Non è esaustiva, ma può aiutare la maggior parte delle persone.
Protocolli supportati (Kopete 1.0.80)
Kopete supporta molti protocolli. Un elenco con dettagli sulle funzionalità disponibili è disponibile nella pagina Panoramica dei protocolli supportati.
Le webcam hanno bisogno di driver
Primo passaggio: installare i driver
Prima di tutto hai bisogno che la tua webcam funzioni con Linux. Questo richiede che sia caricato un driver Video4Linux compatibile.
Prima attiva il supporto video per linux (v4l) nel tuo kernel linux. Se i moduli non sono installati automaticamente, i nomi sono v4l-compat, v4l-common e videodev.
Qui ci sono alcuni collegamenti a driver per webcam comuni su Linux. Se stai comprando una nuova webcam potresti voler controllare queste pagine per essere sicuro di prenderne una compatibile con Linux.

Compila ed installa i tuoi driver (se necessario) secondo le istruzioni sul sito del driver.
Secondo passaggio: webcam con Kopete
Open the Kopete configuration dialog. Go to the device section. Your webcam should turn on and you should see the picture in the preview. If you have a problem with your driver, add yourself to the video group using the KUser user administration tool, make sure your camera driver is working, and try again.
Third step: real webcam use
- Open Jabber or WLM chat with one of your buddies. Use the option in menu to send your webcam stream to your buddy. You should get the preview of your stream in a new dialog.
- Alternatively you can choose the desired action in the context menu of the contact.
Troubleshooting
My camera is a no-name (generic) brand. How can I find the appropriate driver? You will probably find the chipset brand using the "lsusb" command as the root user. Note that some no-name and cheap camera brands don't work on Linux at all, though the spca5xx driver supports an increasing number of chipsets.
I can't receive any webcam stream from my buddies; what's wrong? MSN webcam support is not NAT-friendly. Check your NAT router and forward the MSN Webcam port to your computer port on which Kopete is listening for webcam (see the next item).
Detailed listing of ports to forward for MSN Microsoft provides this info in the following link: http://support.microsoft.com/kb/324214/en-us
| Service | TCP ports | UDP ports |
|---|---|---|
| Incoming voice (computer to computer) | 6901 | 6901 |
| Voice (computer to phone) | - | 6801, 6901, 2001-2120 |
| File transfer (receiving a file) | 6891-6900 | - |
I can receive or send but not both at the same time; port 6891 has been opened for TCP/UDP packets
It seems that you had to forward 6892 (udp and tcp) as well to get both directions working.
How do I receive webcam images through the Yahoo! protocol? You need to have the jasper application reachable through your PATH environment variable. The Jasper application is provided by OpenSUSE from v.10.1 (though not installed by default).
For Ubuntu, use the Synaptic package manager to install the jasper runtime package which is called libjasper-runtime.
Can we expect to see UVC cameras support (http://linux-uvc.berlios.de/)? Kopete shows only green screen when you try to use the camera. Other software (Skype, aMSN) work fine with this driver. UVC camera (Logitech 9000 Pro) is reported as working in Kopete 0.12.7, (Ubuntu Hardy 8.04) out of the box.
