Re: quickcam: "Free VIDEC access campaign", Step 1
It's a good cause, and good luck with it. You have my full support,

Check the wording carefully on whatever NDA they want you/us to sign.
Someday I may want to write my own graphics and/or compression
algorithms; I don't want to sign away my rights to -that-.

I don't know that Connectix would care about this. They distribute a
freeware player for extrating VIDEC-CODEC from AVI files, don't they?
If we scratch this part of the proposed contract, we can do something
like what Bart suggested: write a shared library (ported to each
platform) and "hook" into it from the cqcam/qcam/qcread/etc... Problem
there is, that library could easily be used for file (i.e., non-camera)
I think Connectix would be far more concerned about people freely
distributing a compressor CODEC.

(your English is fine, but check your ^^^ typing.)
Dream on. :) They have posted sample (probably not used in QuickPict)
code for the protocol. I have a feeling that we're better off asking
just for similar sample code demonstrating the decompressor. They won't
give us the whole thing.
... not that we need it, right? I wrote cqcam before I realized they'd
posted sample C code to do similar things.

With care taken to make sure that it can't be used on static files, if
that turns out to be important.
