V4L2 Support Planned?

Post by Blazer » Thu Apr 17, 2008 9:36 pm

I have some of the newer logitech cameras (Orbit MP, Quickcam 9000), that only currently work in linux with V4L2 and/or the uvc driver (So I cannot use them with ZM unless I use mjpeg-streamer as a proxy). I found this snippet at the V4LWiki:

"The linux-uvc driver is V4L2-only. This means applications which support V4L1 only will not work. V4L1 is officially deprecated, and have been removed from the kernel recently, so most drivers have or will switch to V4L2 anyway. "

So this got me to wondering if Zoneminder was going to eventually support V4L2. At first I would think it's not worth it just to support the UVC cameras, but if indeed V4L1 is depreciated and being removed from distros, maybe adding support for V4L2 isn't such a bad idea?

P.S. I would be willing to donate a Logitech Quickcam 9000 if it will help with development :)

Phil is working on V4L2 support, when it will be ready I do not know.

Status of support for v4l2?

Post by alklein » Sat May 31, 2008 5:28 am

Greetings,

I recently purchased a Logitech QuickCam Pro 9000, which requires the uvc driver and uses v42l. I came across this thread, and would also like to know when a new release is available which supports this camera.

I was able to configure zoneminder 1.23.3-1.deb to the point where I have a black square rather than a broken image link, but that's about it.

Thanks,

Adam

Awesome! Any rough idea on when it will be testable? Thanks for all your hard work!

I'm also interested in seeing updates on the QuickCam Pro 9000 running with ZM, In its class, this USB cam has exceptional price/performance and can be useful placed near a ZM server.

Since I'm having problems (as in I can no longer use ZM without re-compiling my kernel), has there been any further development on this?

If Phil was at 95% in april, does that mean we're at 99.842%? by now? :)

When yo uboot up, press escape key and highlight the older kernel to boot to 'til it is resolved. That is what I'm doing.

This, of course will not resolve the quickcam issue

I will have to re-install the older kernel first. I typically clear the old kernels out when I upgrade. Dohh!

As an update, I pulled an older version, and am running fine now. But, am tracking this to see if there's any alpha/beta testing needed.

Also interested in this, since my only cam is a Logitech Quickcam Pro 9000.

Had been racking my brain for ages trying to get it to work and finally decided to search the forum :/ That'll serve me right.

EDIT: Just to clarify, is there no way of making this cam work with ZM atm? Might look at grabbing a different one in the meantime.

Until ZM fully supports UVC cameras, the easiest way to get your logitech 9000 working is to use mjpeg-streamer, which is a lightweight camera server daemon. Then you configure zoneminder to access it as if it were a remote network camera.

V4L2 support has been merged into 1.24.0 so it will definately be in the next version. It needs a bit of testing so there will be Release Candidates available before a proper release. V4L2 seems to work as well as V4L1 but there may be other features of it that I am not aware of and may have missed so there may be other optimisations to apply in the future.

I would be willing to send you a Logitech 9000 camera to test with, if it will help improve Zoneminder support of UVC devices :)

Oh drat! I wish I'd spotted this thread before ordering a Pro 9000 just a few hours ago. :)

Murphy's Law is obviously alive and kicking. I guess I'll be using the mjpeg-streamer fix in the short term, then.
