Description Andrew Fuller 2005-10-06 06:14:37 UTC
Version:            (using KDE KDE 3.4.90)
Installed from:    Gentoo Packages
OS:                Linux

My webcam (Logitech Quickcam for Notebooks) works in Kopete 0.10.92, but the stream is very choppy (I'd say ~2fps).  I'm using the spca5xx driver, if that makes any difference.  I can use spcaview and it gives me 14fps with the same image quality.

I don't know what more info I can provide / would be useful.  Happy to supply more, just tell me what!

It's the intended behavior (at least for now). Each captured frame generates debug info, and 15fps would flood the logs. I also should note that the slow frame rate only happens in the "config panel", it's not a generalized slowness and doesn't affect the speed of the video transmition (implemented in the protocols themselves).
Comment 2 Andrew Fuller 2005-10-07 06:15:30 UTC
I just updated to revision 467922 from SVN, but the transmitted video is the same framerate as the config panel (both what I see as my outgoing image, and confirmed on the other end).
Comment 3 Cláudio da Silveira Pinheiro 2005-10-10 05:03:05 UTC
Well, as the maintainer of the low-level video stuff, I can assure it is protocol dependent, not as a limitation of the protocol itself, but maybe how many times the video image is grabbed by the protocol. It must be changed by the protocol maintainer, nothing prevents the image from being grabbed at 15fps or even 30fps (as it is hardware-dependent, not software-dependent).
Currently I'm moving again, changing home and work, this time from Brasilia to Manaus. Currently I'm at Fortaleza visiting my family, and I have no computer here with Linux installed and neither a linux-compatible video capture device, so I feel sorry I can't help at least for now. I hope next week I'll be able to touch the code again.

Simular behaviour here also with pwc based camera - Logitech Quickcam 4000

Have the same bug here : A Type Flexcam 100 (SPCA561A), Bus 002 Device 006: ID 04fc:0561 Sunplus Technology Co., that works with spca5xxx drivers (12/12/05 version). With Spacaview or qastrocam (2 video grabbers) I have a fluid image (spcaview calculate a 8 fps rate). Under Kopete, on Configuration Panel AND viewing, this framerate decrease to 2-3 fps.
I'm using Kopete 0.10.93 (0.11 B2), kde 3.5.0. (mandriva cooker)
Is it a debug log pb ?
Comment 6 Cláudio da Silveira Pinheiro 2005-12-19 15:51:04 UTC
Ok. I have a patch to fix it (at least for the config window). But curently I'm in Manaus. It means rainforest. And means no easy internet connection. I'm typing it from a cybercafe that doesn't allow me to plug the pen drive with the patch, so I'm not able to send it, neither. And to be even funnier: Unemployed. Want to know more? No flight tickets befone new year's eve. So I'm stuck here for at least 2 weeks. Without bed. Without a freezer. Without an air conditioner. Drinking hot water and eating cookies.
Sorry for ranting about my own life here, but I just realized the thing about the flight tickets and I'm outraged. I promise I'll not start a bugblog (blogging on bug tracking system) despite my life being so buggy these days. It's a thing I _really_ need to fix.

courage !! here (France) it's snowing ;)
we are waiting for your patch ;)  (paste it here ?)
Comment 8 Cláudio da Silveira Pinheiro 2006-05-02 13:15:14 UTC
Kopete a/v config panel defaults to the fastest speed the device can handle.
Comment 9 Jonathan D. 2007-01-11 21:19:47 UTC
what about the transmitted video framerate ?
Comment 10 Xavier FACQ 2007-01-12 08:47:59 UTC
Hi,

This problem is the same than this one: http://bugs.kde.org/show_bug.cgi?id=131861
It's resolved. We just need a spinbox somewhere in the webcam configuration.

bye,
Xavier

I can confirm that the video is choppy.  IT's not only choppy, but it falls way back, WAY back.  It may start with a 2s delay, but the delay becomes progressively larger and larger until the connection dies.
