I've never used Xen but if you can boot a CD or iso in it with the disk image as the primary hard drive you could probably chroot into the file/drive and run grub to make it bootable? I would assume the script adds some kind of partition table to the dd'd image, and grub would add itself to the ...

As an interesting sidenote forcing 20fps in guvcview gives me 9.5fps all the way up to 1280x720, but all the other options output 4.5 regardless of resolution.

Does this say anything? If I had a CD drive I'd try ubuntu, but it's dead

It's linked in the first post if you'd like a look

Random thought - are all the cores enabled in BIOS? The attached .config looks fine to me...

Not sure where I should be looking on the 4 cpu list - the %us's peak up to around 50 (when added together, the highest one peaks at 25) with the stream running compared to around 20 without (with a single peak of around 10). It flicks between 0.5 and 2% cpu on the main table? That was at 1280x720 ...

Oh yeah, that would be more useful :oops: There are plenty of them!

Hi :)

I can't recommend a controller but it's good to remember that all Linux distros use the same kernel, as the drivers are in there nothing extra is needed for Gentoo support. If you find one someone is using in another distro it will work in Gentoo :)

RAID 5 is designed so that one drive ...

I'm on a new kernel now, I was on 2.6.34-something before, but it hasn't helped...

Portage 2.1.8.3 (default/linux/amd64/10.0, gcc-4.4.3, glibc-2.11.2-r0, 2.6.35-zen2 x86_64)

You can choose the fps in guvcview, but it doesn't change anything.

I tried mplayer and after a while killed it, the last line reads Which doesn't sound healthy...

Thanks NeddySeagoon, shame it wasn't a quick fix though...

I've just taken the webcam out from it's cupboard and into the light but that doesn't help. Found an option in guvcview to display the FPS and even as low as 320x240 it reads 4.5fps, the same as it did in Windows. I'm going to change the ...

When you say it is better with the netbook, you mean the same camera ?

The same camera 8)

Are you testing it on both computers with similar lighting?

In low light webcams often capture with lower FPS to catch more light in each single frame.

Try media-video/guvcview. Disable auto exposure ...

Thanks NeddySeagoon - I couldn't think of any reason it should be but nothing else makes sense! Shame I didn't notice your post before the weekend was over really...

Yup! The only thing that makes sense of it is the graphics card being 5 years old and not at all high end in it's day, but newish onboard Intel isn't exactly great either.

It's just as bad in Windows as Linux (which is a relief - I don't want to go back after years of Linux - still can't scroll a ...

I can record at 640x480 on a netbook far better than 320x240 on this PC - the PC is better (apart from graphics) so should at least match the netbook.

The webcam box claims 30fps at 1280x720 - I see no reason not to achieve this!

Hmm... so what else could it be? Two systems, both running Linux where the only better thing on one is the graphics. Oh, and the PC is running 64bit but surely that shouldn't affect anything? I tried recording on a fresh install of Windows 7 using the bundled application and it got a steady 4.5 fps ...

I recently bought a webcam that uses the UVC driver - it functions fine. My problem is the framerate, which is just as bad in Windows as Linux (I installed it especially to test :P)

My main PC is a Xeon 3220 (same as a Q6600) with 8gb of DDR2 but I'm thinking it's limited by the graphics card - a ...

I too have been struggling with this for a while, but just found the answer:

Enjoy!

I think the main problem with SATA dvd drives and live CD's is down to the motherboard controller.

I'm using a Samsung SH-S203D, everything works as if it were IDE but I thank my trusty bad axe 2 for that . If you're not reading at full speed it's quite quiet too

Good spot champ - even in the first post hdd is listed as a CD-ROM drive, not a CDRW which is a very good reason for it not to be able to write anything. So obvious no-one saw it!

Interesting - what is "wodim" that it mentions using /dev/hdc? I don't have it installed. What arch are you running?

Also your CD drive is hdd, so if that bottom code was a copy/paste it's no surprise it didn't find hdc...

Sounds like a sampling rate problem - look into forcing it to either 44100 or 48000kHz depending which it isn't defaulting to. I'm off to work so no time for tips but that should help you find an answer

I've always used -dev=/dev/whatever, not a number, and it works fine - you have no "-" before dev and are using a number... one or both of these must be the problem
