6.1. Il video è lento o ha una bassa risposta. Cosa si può fare?
You may have set "ximagesink" (X Window System (No Xv)) as video-output. This means that your CPU is doing all the work. Change it to "xvimagesink" (X Window System (X11/XShm/Xv)) in order to let your graphics card do the work.
To change this setting, run the gstreamer-properties command, click the Video tab and change the appropriate setting.
6.2. Ho un Mac con iSight e una scheda grafica ATI e i colori sono strani.
Questo è problema dovuto alla scheda grafica ATI, ma è possibile aggirare il problema. Cambiare l'uscita video in personalizzata e inserire quanto segue:"ffmpegcolorspace ! video/x-raw-yuv,format=(fourcc)YV12 ! ffmpegcolorspace ! xvimagesink".
To change this setting, run the gstreamer-properties command, click the Video tab and select custom from the drop down menu.
6.3. La webcam funziona con gstreamer, ma non con Cheese. Cosa c'è che non va?
Using the gstreamer-properties mentioned in the above question, try changing from xvimagesink to ximagesink or vice-versa. If this still does not work, run cheese --verbose on the command line and copy the logging into a bug report in our bug tracker.
6.4. La webcam funziona con altri programmi quali Ekiga, Camorama, ma non con Cheese. Cosa c'è che non va?
Vedere se la webcam funziona quando provandola in gstreamer-properties. Se qui funziona, ma non in Cheese, compilare una relazione di bug nel link bug tracker.
6.5. Where does Cheese store my photos and videos?
Cheese stores your pictures in a folder called Webcam inside the XDG-Directory set for Pictures (in most distributions its ~/Pictures/Webcam). The same applies for Videos: ~/Videos/Webcam. XDG is a standard to declare default folders in your system. You can find more information about XDG here.
If the XDG-Path is not set on your System, cheese has a fallback solution: it will store both your pictures and videos in ~/.gnome2/cheese/media. This is the default directory for your media if you have an older version of Cheese.
How to set an alternate path is described in Sezione 4.2 - GConf settings.
Attention: leave this settings blank if you want Cheese to use the default directories.
You can also save your pictures to an alternate location from within Cheese. Please see Sezione 5.2 - Salvare foto e video in una posizione diversa for information on this.
6.6. La webcam Quickcam Express non funziona con Cheese...
oppure gstreamer e vedo errori come "Not enough buffers. We got 1, we want at least 2" nell'output di Cheese. Con driver "qc-usb".
Cercare di eseguire qcset /dev/video0 compat=dblbuf per abilitare la modalità di compatibilità a doppio buffer, quindi riavviare Cheese.
6.7. Messaggio di errore: «Nessuna macchina trovata»
"When I launch Cheese, I get the message 'No Camera Found' but I have my webcam plugged into my computer".
There are many situations that can cause this, and the exact problem that is causing it needs to be isolated. If possible, try each of the following to try and get your webcam working:
- Plug your webcam into another computer. If it works there, then it is a problem with the connection to your computer, or the operating system if it was a different one on the other computer. Check the ports on your computer (try another one) and consult support for your particular operating system.
- See if your camera is being detected by your computer. On Linux, open up the terminal or console and type "dmesg" before you plug in your webcam. Notice the most recent entries, and then plug in your webcam. Type "dmesg" again and see if the most recent entries differ. If the message mentions a USB device being detected, and your webcam is the only USB device that has been changed, then your computer is detecting your webcam fine. If not, then test to see if the webcam is working on another computer. This may only work with USB webcams.
- As Cheese uses the gstreamer backend, it is most likely because gstreamer is not detecting the webcam (or gstreamer has become corrupt). Please contact support for the particular operating system that you are running with as many details as possible. For Ubuntu, please use the Ubuntu Forums.
