Extremely low framerate, not related to CPU/GPU X11 usage

[GoogleCodeExporter]

What steps will reproduce the problem?
I wish I could tell you.

What is the expected output? What do you see instead?
~30FPS on my webcam. Instead, I see a very choppy (5fps) feed. My webcam works 
perfectly outside of WCS. It's not a streaming issue or an issue of CPU/GPU 
capacity. I have tried switching from 'No Xv' to 'X11' in VLC but have seen no 
change.

What version of the product are you using? On what operating system?
Ubuntu 12.04/WCS 0.57beta4

Please provide any additional information below.

This happens when playing movies too.

ive had this same issue for a while, at first i thought it was caused by the 
app showing 100% CPU usage, even tho my actual system usage wasnt but even in 
the latest 0.60 alpha release, the java memory built-in the app isnt anywhere 
near capacity, its only 50mb of a possible 700mb but the actual preview windows 
in the app show lag.

the first in the blue area shows just a slight delay but then if i activate the 
other preview in the upper left of the app it shows about 1-2 MORE seconds of 
delay and that obviously translates into what i see when i look at the flash 
cam of any major site, meanwhile if i just plug in my cheap Xbox Live Vision 
cam its steady at 30fps in any flash app.

i never had this issue with the old version of Webcamstudio that was in the 
Ubuntu repos, but since upgrading both Ubuntu over the years and flash/java i 
dont know what exactly could of causes this to change, but i now have an even 
more powerful computer than i did then but i didnt have these issues then, so i 
dont expect it to be an issue on my end in terms of hardware now either.

its too bad manycam wont just fund some devs to work on a linux distro since 
that appears to be the most popular windows/mac app otherwise its either Live 
with washed out bad lighting using my webcam to capture my desktop or use this 
app with horrible delay but great 1:1 picture quality from the source =(

Pretty much my same issue in greater detail. I have an i7 2600K @ 4.3ghz and 
8GB of DDR3 RAM, as well as a Corsair F3 SSD. It's not an issue of hardware.

same problem
when i share a recorded video as the webcam, the framerate is very very poor 5 
frames per second i would say
i have a quad core, 4gb ram , performance don't go over 25% in either CPU or 
ram.
it's clearly a software problem since even in the presentation on youtube the 
output was laggy

Thank you for the reply. Unfortunately I think WCS may now be unmaintained. 
There has not been an update on any support issue in months. It's a shame.

Could you all please test the latest Daily build from our PPA: 
https://launchpad.net/~webcamstudio/+archive/webcamstudio-dailybuilds and 
report back?

When testing please compare the performance when using the webcamstudio-dkms 
package against using the v4l2loopback-dkms package..
Thanks
And sorry for the lack of support but the project was a kinda freeze because 
Patrick was too busy...
Now there is a new development Team...
