It sounds to me that a Bt848/849/878/879-based frame grabber is good enough for your application. Also, the v4l/bttv driver should work well for you. Charlie X.

I am trying to build a machine vision system. The idea is really straight-forward. I capture individual frames at 25fps or every 40 ms (PAL standard). The capturing format is YUV 4:2:2. Once I have captured a frame, I process it by feeding it into a vision processing library. Once this is done, I get the next frame, process it and so on. I understand that for you guys this is dead simple, but you can also realise that the chipset shouldn't be really important, since I am not using any fancy functionality. Mind you, I don't understand the use of the chipset in a frame grabber, that is where it fits in. I'm just using the board as a means to getting frames from a PAL camera fast. Nothing more. I hope this helps clarify what I'm trying to do. Once again, thank you. -- Georgios Kapetanakis Department of Computer Science University of York ----- Original Message ----- From: "Alan McIvor" <alan.mcivor@xxxxxxxxxxxx> To: <video4linux-list@xxxxxxxxxx> Sent: Tuesday, October 15, 2002 9:52 PM Subject: Re: About a frame grabber > On Tue, 15 Oct 2002 19:37:06 +0100 > "Georgios Kapetanakis" <georgios@xxxxxxxxxxxxx> wrote: > > > I've also checked what Charlie told me, but since I have excellent > > recommendations for the Omnimedia P1S, I'm reluctant to look for something > > else.
