Cheese webcam video slow/jerky in F11 on a Dell Inspiron 1520
Last modified: 2009-06-15 09:53:29 EDT
Description of problem:
Video in Cheese is slow/jerky in F11 on a Dell Inspiron 1520. In UCView (for example) it is smooth with >30fps
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Start Cheese webcam booth in F11.
2. Observe slow/jerky video
Bus 002 Device 003: ID 05a9:2640 OmniVision Technologies, Inc. OV2640 Webcam
01:00.0 VGA compatible controller: nVidia Corporation GeForce 8600M GT (rev a1)
(using nvida driver from rpmfusion)
Cheese by default uses the highest resolution your cam can deliver, which sometimes may result in low framerates. Go to edit -> preferences and select 640x480 or something like that, that should make things better.
Thanks, that does help, if I reduce it to 800x600, anything above that is still slow (which is surprising considering I have a Core2 Duo @ 2GHz and nVidia 8600M graphics)
Still, why does it default to 1600x1200 when the max display resolution is 1280x800? Shouldn't it try to match the display a bit better?

Well, its probably a usb 1.1 device, so the usb bandwidth is limiting the framerate.

Good point, can you please file a bug about this upstream ? :
