Re: [gentoo-user] Re: {OT} video monitoring
I've been using motion along with USB cameras for a while. I need to expand my monitoring capacity and I'm wondering if I should consider changing software or hardware. motion seems fairly dead but is stable. I'm reading conflicting info about the current status of zoneminder. Is anyone using IP cams? Hello Grant, Some years ago, the slickest webserver plus zoneminder setup was this http://www.gossamer-threads.com/lists/cherokee/users/2450 cherokee + zoneminder + php Another solution is to get some pci cards that take a coax input from a coax cable (RG/59 or RG6 for distance) directly into the PC. There you can convert the streaming video into h.264 and move it around the ethernet. Encoder (coax to h.264) pci cards use to abound such as Qsee, Avermedia etc etc. You can also get embedded boards from TI that include the DaVinci package which take in coax and convert it to H.264. I use to get the best information about the key chips reading the linux kernel driver documentation found in the old drivers. Many of the drivers (most?) have been unified and the in-driver documents therein will be mostly useless, so old 2.4 and 2.6 drivers for specific chipsets is the best source, if you really want to dig into video over IP. Most currently manufactured IP cams go to great links to make their hardware a black box on what they are doing to output the H.264. [2] Furthermore, you have to delve in the container versus the packets when you find incompatibilities. Many of the advanced ethernet sniffing software packages have h.264 filters build in [1]. It's all H.264, just a lot of software gymnastics to frustrate folks from rolling their own video solution. If I were to get serious about video/IP, I'd go with VP8 (google's standard) and find a codec (opensource) that could be put on a micro processor board; pandaboard? [3]. Googling around and I'm sure you can find something. [4] usb video sucks, once you try to scale up for any sort of serious video surveillance system; imho. hth, James [1] http://www.wireshark.org/docs/dfref/h/h264.html [2] http://en.wikipedia.org/wiki/VP8 [3] https://wiki.linaro.org/WorkingGroups/Middleware/ Multimedia/Specs/1105/OptimizeVp8Decoding [4] http://www.webmproject.org/tools/ After reading everyone's responses, I do think I'll stick with USB cams and motion. Can anyone recommend a good USB cam for indoor use with a nice wide angle lens and mounting threads? It doesn't need to be cheap. - Grant

Nouveau works as it should here, and I think it always has. The two snags I know of are that it doesn't allow access to the graphics hardware by, e.g., BOINC, and that it doesn't have hardware 3D acceleration. The latter doesn't bother me at all, though CUDA would have been useful. -- Regards, Peter

Mick, I've been running nvidia-drivers on my Gentoo laptop for three years and have two major problems: 1. Any particular nvidia driver version is only compatible with only certain kernel versions. This condition is due to the way the NVIDIA driver works. Gentoo portage was just not designed to handle such a rule package x requires kernel y so it is left to us users to deal with via masks. For some reason (?) I only had to deal with this rule during the period ~July 2013 - October 2013. 2. The latest stable version of the nvidia drivers do not allow gnome-terminal windows to close. This problem too just started happening after years of trouble-free gnome-terminal closing. It is frustrating... but I'm stuck with NVIDIA-drivers because I use CUDA. If 1) this sort of thing bothers you and 2) radeon doesn't have similar problems, then by all means please switch to radeon and let us know how it goes! PS: Installing the CUDA runtime and SDK is easier on Gentoo than on any other linux distro. Chris

Two things give nVidia a bad rap (both unfairly IMHO) 1. The latest greatest drivers do often give trouble. What nVidia considers stable is not what the world considers stable, it's better described as good enough to be released for testing.IOW about the same as ~arch. Graphics hardware is hard to test, there's just so many of them, so many code paths and so many X-server versions out there. nVidia usually gets it right eventually, where eventually is definitely longer than one week 2. They drop support quite early in current drivers for old cards and relegate it to legacy drivers. This is their marketing strategy, they chase the latest and greatest (it's a fast moving market and if you snooze you lose). If your card is old enough to have no realistic support at all, there's Nouveau. So basically it a lot like the kernel. If you want the latest stuff, use the latest driver and deal with any fallout. If you want stability, stay two versions behind at least -- Alan McKinnon alan.mckin...@gmail.com

Code is written to use CUDA. if not, it can't use it. Your question should be Do you intend to use software that is written for and will benefit from CUDA? -- Alan McKinnon alan.mckin...@gmail.com
