The dom0 becomes unusably slow until I manually destroy the domU. The domU runs 2.6.18-128.1.10.el5xen with video4linux-kmdl-2.6.18-128.1.10.el5xen-20090415-88.0.4.el5 (there are no video4linux-kmdls for the latest kernel yet). Manually unloading the modules before shutting down has no effect. Without video4linux-kmdl installed, everything works fine. I hope you can help me. Regards, Chris

All, There have been many requests for added kernel features that the upstream provider left out of the standard kernel. (ReiserFS, Video4Linux, Firewire support, XFS, NTFS, JFS, etc.). We want the main release CDs to contain a standard kernel for compatibility and stability reasons. CentOS is created as a clone, and it needs to be as close as possible to the upstream distro. That being said, the 2.6.9 kernel has lots of features that a...

is there a utility or SOME method to determine which /dev/videoX (like /dev/video0 or /dev/video1) is being used by a device??? Example I have a USB camera and a USB TV module how do I determine which device is on /dev/video0 and which is on /dev/video1 I have seen perhaps a way in dmesg but I am looking for the BEST way and the correct way. Thanks, Jerry

Hi guys. Just curious if there's any progress on bug 16147 http://bugs.winehq.org/show_bug.cgi?id=16147 Hope this is the place to ask. Bob

Hi! I am new to video encoding and streaming so this question may sound silly. However I want to create a simple application which would get video frames from video device (video4linux) encode them using theora and then send to clients. The question is: do I have to encode the stream for each client seperately? It would be ideally to have one encoded stream and send it to as many clients as it is needed. I wanted to do so, but I have seperate Ogg streams for each client and whe...

I just saw this project referenced on the video4linux mailing list, and I thought others on this list might be interested (assuming they don't already know about it): http://www.opencircuits.com/OpenHDCapture To summarize, the goal is to develop an open hardware device that can capture video at 720p30 (1280x720, 30fps). At the moment I am not s...

Hi List, Does anyone know of any type of radio tuner software available for CentOS in either 32 or 64-bit versions? The card is an ATI X600. I've got the video driver from ATI installed, but they do not have any other user level software available. I think I remember reading something about some software being available for the BT chipset, but I'm a tad out of date on that.

...ting much traction from Red Hat as far as them updating the kernel. So every time there's an updated kernel, I have to rebuild the srpm. I figure that this is the kind of situation that -plus is meant to solve... I've already had to switch one of my boxes over to plus today given that the video4linux srpm (from atrpms) won't rebuild easily on 2.6.18-92.1.6.el5, and I'm thinking that having both on plus with everything I need in them would make it a lot easier... (There's already precedent here... I found linux-2.6.18-bz443853_powernow_null_deref.patch and linux-2.6.18-bz444759_hi_i...

Irritating quirkyness: we have a bunch of videocams. To use, we use gspca. Usually, on an upgrade, I just go into the gspca directory (which appears, from their website, to have not been updated since '07), make clean, make, make install. Having gone up to 5.5, did the same. What's happening now is that it works, delivers the mpgs... but dumps errors in the logs: <snip> kernel:

Just curious about kernel requirements after the upgrade. I've been running the 2.6.9-11.106.unsupported kernel for some time. Now I see that the base kernel is up to 2.6.9-22.EL. Are there any plans to upgrade the unsupported kernel? Should I be using the newer kernel after the upgrade? Does it make any difference? Not trying to be pushy; just looking for information. Thanks for all the

So, I keep seeing references in the codebase to "video conference" uses for Asterisk. However, I am unaware of what end devices are currently supported by Asterisk. Searching through the archives for the term "video", I see a few other people have asked the same question, with no real reply. Nobody, it seems, has actually tested any video phones on Asterisk other than

What does the CentOSPlus kernel have that the standard kernel does not? It is just additional drivers and modules?

Does anybody know where I can find a driver for a Logitech E2500 webcam. I'm running CentOS 5 on my desktop and want to add a webcam for skype use. If I can yum install a driver from one of the repos that would be great. Andy

Hello, I need to do some analog video capture and I was wondering what is the status of this in CentOS 6. The last information I could find was here (obviously for CentOS 5): http://lists.centos.org/pipermail/centos/2009-September/082521.html Could anybody recommend a not-too-expensive video capture cards (PCI, USB, fireWire, ...) which would be well supported (drivers easily available in base,
