Webcam "capped" at 4.5fps?

[suicidal_orange_II]

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 )

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 Geforce 7300gt (with properly configured nvidia driver) while my netbook has some slow atom cpu, 2gb RAM and onboard Intel graphics. The netbook records better videos

Can anyone confirm it is just the age of the video card that would cause this? I don't game and this card still does everything else I want it to, but I need a working webcam so if replacing it will fix my problem I will but there is no mention of graphics card requirements on the box...

Thanks for any thoughts

EDIT: Seems it isn't to do with the graphics card as it still sucks at really low res - any other ideas welcome!

[Kobboi]

It's just webcam video, I doubt the graphics card has anything to do with this

[suicidal_orange_II]

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, looked about the same as in Linux. I've tried different USB ports (including the one used for burning and installing the Windows DVD) so it's not that. I just want it to work!

[Kobboi]

So you have the same performance on another OS? Why expect better performance then? Try capturing on a lower resolution.

[suicidal_orange_II]

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!

[Kobboi]

But just to get this straight: your "better" PC gives you worse performance, both on Windows as Linux?

[NeddySeagoon]

suicidal_orange_II,

Please post your /proc/bus/usb/devices - its not graphics card related.
The framerate from the webcam is not related to the framerate the graphics card draws.

[suicidal_orange_II]

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 non-focused window for a start...) so it must be hardware related...

[suicidal_orange_II]

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...

Here is the relevant section, doesn't mean much to me

[dmpogo]

When you say it is better with the netbook, you mean the same camera ? Or netbook built-in camera is better ?

[iss]

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 and try different framerates.

I'm sat in the same chair, the webcam isn't moving from it's very dark place atop the monitor... sounds like that could be worth changing!

I have installed guvcview and I can make myself look like a ghost, but the framerate gets worse if anything with auto exposure disabled. Thanks for the app though, looks like it has some useful options.

I'll try moving the camera this evening and see if that helps - thanks for the advice

suicidal_orange_II,

I need all of /proc/bus/usb/devices - I cannot use a fragment.
I want to look at the entire file to check for bus over current conditions and the arrangement of your USB devices on your root hubs.

The file as it stands does not mean much to me either but I was going to feed it to usbview. If you want to see what I will see,

Code: Select all

emerge usbview

Rules to check for:-
USB1 and USB2 devices must not be mixed on the same root hub, or you only get USB1 speeds. You cam is a USB2 capable device but USB1 does not have the bandwidth to make the best of it.
Any root hub an provide at most 500mA for all attached devices, when you overload a root hub funny things can happen.

From the fragment you posted,

Code: Select all

C:* #Ifs= 4 Cfg#= 1 Atr=80 MxPwr=250mA 

tells that your cam needs 250mA, leaving 250mA for other devices and

Code: Select all

 S:  Manufacturer=Linux 2.6.34-gentoo-r1 ehci_hcd 

is good as its attached to a USB2 capable controller, using the USB 2kernel driver.
As I have explained above, that is not sufficient to get you USB2 speeds.

Thanks again

[NeddySeagoon]

suicidal_orange_II,

Thats all in order. You have two USB 1 devices, each on their own root hub.
Your cam shares a USB2 root hub with a powered USB2 hub. So its all USB2. The total power required is 252mA, so thats well within spec.

In short, your USB setup is sound.

[suicidal_orange_II]

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 title of the thread in the hope of finding the problem...

[chithanh]

Can you use mplayer to set more fps?

Code: Select all

$ mplayer tv:// -tv driver=v4l2:width=640:height=480:device=/dev/video0 -fps 15

[suicidal_orange_II]

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

Code: Select all

v4l2: 132 frames successfully processed, 646 frames dropped.

Which doesn't sound healthy...

[NeddySeagoon]

suicidal_orange_II,

Code: Select all

v4l2: 132 frames successfully processed, 646 frames dropped.

Suggests that the cam produced almost 6 times as may frames as your hardware could process for display If you were really getting 4.5 fps and nothing else has changed, the cam is doing 26fps.

This suggests the problem is between the cam and the graphics card.

Please post the output of

Code: Select all

emerge --info

and the content of

/proc/cpuinfo

There are 4 cpu's but they are all the same...

Thanks again for your help

suicidal_orange_II,

I don't believe that that hardware can do no better than 4.5 fps - whatever the graphics card, even with my old 8 bit ISA bus 64k VGA card.

Your use flags look good for multimedia applcations.

When you play the cam video stream in mplayer, what do you get in the terminal ?
All of it ... including the mplayer command.

I've ran the same command at 320x240 and 1280x720 and get about the same number of dropped frames

I'm glad it's not just me expecting a little more

suicidal_orange_II,

The CPU has to do colour space conversion from the Packed YUY2 provided by the cam, to RGB for your display.
