Therefore with a little bit of further tweaking it will presumably come
out exactly so. Namely, I have to remember where to stick the two
dimensions into the header.

Today's progress, so far:

1. I managed to look up where the width and height go, and indeed the image comes out nicely when the dimensions are appropriately entered.

2. The same header that I peeled off from your JPEG image also works for images from my cam. That is, I took your header, converted to text, and corrected the dimensions. Then I took a frame extracted from the snoop log of my camera, prepended it with your header, and I get a recognizable image. I really should try the same with a header from my own camera, of course. For one thing, the image was recognizable but not beautiful, and it occurs to me as I write that there might be some problem other than, perhaps, an unlucky choice of frame. But we do have a demonstration that there is some high degree of compatibility.

Finally, I succeeded in creating a couple of AVI files. There is one difference between the two AVI headers. Yours has

Jeilin  Technology Co., Ltd.JL2008V2C0070010

and mine has only

Jeilin  Technology Co.

So what is the version of my camera? They don't say, and therefore I still don't know. We can hope it does not matter very much.

I will have a go at writing a module for them, and we can see what happens after that.
