Description of problem: When using amsn to chat with webcams going for both participants amsn tends get into a 100% cpu usage scenerio quite easily within a few minutes. This naturally causes amsn to grey out all it's chat windows, webcam windows freeze in one frame and cease to update. 23853 david 20 0 256m 58m 7700 S 65.9 2.9 8:19.45 wish I am unsure how to debug this. Version-Release number of selected component (if applicable): amsn-0.97.2-1.fc10.x86_64 How reproducible: 100% Steps to Reproduce: 1. start chat with webcams going for both parties Actual results: as above Expected results: joyful continued Additional info: x86_64, da_DK.UTF-8
Thanks for the bug report. Can you tell me what webcam and driver you use? I tried to reproduce the problem but cpu usage stayed below 15 percent. Do you get similar results when using a different program to view the webcam?
This is a Creative Live! Cam Optia AF (uvcvideo), no issues with other webcam apps observed.
http://forum.eeeuser.com/viewtopic.php?pid=338942 seems related, not sure what to do though.. seems driver related
if it helps, it didn't used to happen, only started in the last maybe 2 weeks or so.
Hmm, this might have something to do with libv4l then. Maybe Hans has an idea about it? See also https://fedoraproject.org/wiki/Features/BetterWebcamSupport
I doubt this is caused by libv4l, but lets give it a shot. David, can you please downgrade to the amsn version from here: http://koji.fedoraproject.org/koji/buildinfo?buildID=58847 That one does not use libv4l and is otherwise identical. If that one reproduces the problem too it is not libv4l related (but probably the driver, try downgrading the kernel next).
no dice with the amsn version, what kernel version would you suggest starting with?
(In reply to comment #7) > no dice with the amsn version, what kernel version would you suggest starting > with? Try the 2.6.26.x one from F-9 updates, if that one does not have the problem, go to koji: http://koji.fedoraproject.org/koji Search for kernel, and try a couple of 2.6.27 ones spread apart.
You can also try the amsn version here, since that is the version you might have run previously: http://koji.fedoraproject.org/koji/buildinfo?buildID=35735
I'd rather not downgrade to a F9 kernel as I am on F10, I suspect that will break everything else. I will search though koji, I figure going back a month would be good, then move back or forth depending on the result. Should narrow it down I hope.
This bug appears to have been reported against 'rawhide' during the Fedora 10 development cycle. Changing version to '10'. More information and reason for this action is here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
David, do you still see the issues you reported?
occasionally, on both F10 and rawhide. Also using the lastest SVN of amsn. I can't seem to catch it in the act though.
This message is a reminder that Fedora 10 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 10. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '10'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 10's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 10 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
Fedora 10 changed to end-of-life (EOL) status on 2009-12-17. Fedora 10 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
