Framerate of webcam with uvcvideo is too low

[Christoph Langner]

I own a Trust 2MP Auto Focus Webcam which worked very good on Jaunty until a couple of weeks ago. Right now i noticed that with the latest updates of Jaunty the webcam delivers less frames per seconds than it used to show. In other words i see a stop-motion movie. Usually it has up to 30 frames/sec and, but my guess it is now working with 5 frames/second. Others noticed this too (see bug #220595)

I don't know what happened. But after a couple of reboots, the webcam delivers it's full frame rate... Bug marked as invalid...

i have the same slow fps problem with the Creative AF 2MP webcam and it does not get faster after a reboot. In Ibex I was getting near 25 fps in 640x480 via GUVCVIEW and now in Jaunty I am only getting 7fps in any resolution.

I'm getting the same problem with a Logitech Quickcam Pro for Notebooks. No matter what resolution, I get around 5ps. It's USB Device ID is 046d:0991.

i'm seeing this issue too. i don't use webcam too frequently, so i can't be sure which update broke it. but last time i used it, it could do 30fps at 640x480, now it's barely 5

I had the same problem with a Logitech QuickCam S 7500 UVC (046d:09a2). The problem went away today when I upgraded. I'm now running kernel 2.6.28-16-generic (2.6.28-15 before). luvcview is now reporting 20-30 fps (<5 fps before) :) I haven't closed this ticket, maybe there are still problems with other products...

[Spode (spode-thinkabouttech)]

I'm still on -15 here. I'll give it a shot when Karmic comes out :)

me too, still 10fps tops

my device is genius iSlim 2020AF (0458:7055)

Same problem for me on Jaunty (2.6.30 custom) or Karmic (2.6.31) with the built in cam on a Lenovo T400.
Cheese and Skype are over exposed and have slow framerate ~5fps. However luvcview is crystal clear and snappy ~30fps. I think its an overexposure problem. Like I said, Cheese and Skype are way too bright and very motion blurred, but on luvcview you can lower the exposure until it looks right.

The solution I think is to provide a way to adjust the exposure time in those programs, similar to http://brainstorm.ubuntu.com/idea/12138/. Until then, does anyone know if the defaults are sitting in some config file somewhere?

[Marius (mm473)]

I should've googled for 15 more minutes... here's a solution: Download guvcview from http://guvcview.berlios.de/. Then run guvcview -o which just opens up a control panel. Then run Cheese or Skype or whatever, and play around with the settings until you get good video.

[javierpedros (javierpedros)]

Hello:
guvcview there is included in repository ubuntu. I solved with this app the low frame rate dismark "Exposure,Auto Priority" option.

Hi Christoph,

If you could also please test the latest upstream kernel available that would be great. It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream-testing' text. Please let us know your results.

Thanks in advance.
