[Discuss] streaming webcam
I am looking for a very low latency simple webcam program. I want to be able to see the video from my laptop on my android fairly snappy. Most of the things I've seen introduce about 1/2 to a full second latency. So when I move my hand, I see the delay. I want to get rid of that I need it to be mostly instantaneous. (1) is it possible with Linux and USB2 (2) If so what software (3) what camera. Anyone know? ___ Discuss mailing list Discuss@blu.org http://lists.blu.org/mailman/listinfo/discuss

Also, I have a bunch of webcams, and the one main problem I see in them is that they are SLOW. With very little motion, they seem OK, but if you move them quickly they blur the image terribly. It is important that the effective shutter speed is quick enough that moderate motion of the camera does not blur excessively. Am I asking too much? Do you guys know of anything, I've been looking. I have more than half a dozen different webcams ranging from the built-in laptop cameras to various USB2 devices, which, when all is said and done, are basically logitech quickcams.

Unfortunately, the application calls for a webcam, or at least a USB video camera.

Re: [Discuss] streaming webcam
I've done some video acquisition at work. We have been using bt848 based PCI and PCIe cards for many years. They are cheap and fast, but since they are considered consumer grade, they are subject to change without notice. I'm not sure what we use as a camera with those boards, I only care that the pixels get delivered on time and in order :-) I suspect the security cameras may be a good choice.
