Embedded Linux And Video Capturing? 11
RapaNui asks: "I'm working on a project that uses a remotely controlled camera for video and still work. It currently uses a small board camera and a microwave (analog) downlink for video (the video feed is only used for targeting the onboard DVcam and still camera). Anyway, the telemetry downlink has just been upgraded and we now have 50-60 Kbps available that (if possible) we would like to use for a video downlink. All we need is 1/4 frame (PAL, 384x288) at around 2-5 fps What I was thinking of is a PC/104 or similar PC, running Linux and a vid-capture card (or an old parallel port video capture box - Snappy?). Whatever it is needs to be relatively small and light. Are there any usable (under linux) PC/104 or similar video capture (or still capture) cards? Or is there a unit (like some of the cams made by Axis) that could take video (composite or S-video) in one end and dump out a serial data stream at the other end? (This would be preferable, 'cause it would mean less hardware, and complexity on that end)."

On the other hand, since you don't need to crank through realtime capture and editing, the available Linux solutions might work for you. But I'm curious whether or not you actually need to limit yourself in terms of OS.

I'm not sure if this breaks the bank on size and weight requirements (or whether you even have a PCI slot on your SBC). I would suspect that some of the small USB capture devices might be of interest to you if your SBC has a USB connector. Those tend to be ultra-light and can fit in your hand.

As a bonus compared to the WinTV card you mentioned, the card is rather light with only a single RCA composite video in connector, and a small power outlet for the camera, and the board itself is only a half height board.
Last I know of 3Com took over the manufacture if these, and currently don't even list them on thier page, so they might not even make em anymore, but, it maybe possible to find some on Ebay, or elsewhere on the net.

For reference while shopping, the Video4Linux [linux.org.uk] home page lists major hardware types. V4Linux is included in recent distributions, particularly with the 2.4 kernel. As I noted elsewhere, some manufacturers not listed here also mention Linux.

If you need to use a frame grabber, look at the Matrox Meteor. Supported under Linux and they have a PC-104+ version. I don't know the status of support for the Meteor II, last I knew it was in progress.
