Take for example indiegogo (http://www.indiegogo.com/).
One way to do it (fixed funding):
You would register a campaign say "Relicensing Yadif to LGPL" and define a
campaign goal, say 20000 Euros.
Then you would announce the campaign wherever you like (probably on
ffmpeg-user) so interested parties can participate.
They go to the indiegogo website and pledge an amount (this is legally
binding) which they have to pay, if the campaign goal (20000 in my example)
is reached. But they don't have to pay anything, if the campaign goal is
not reached. However, often the campaign goal is even exceeded (e.g. the
Kdenlive refactoring campaign, which was how I came across Indiegogo first,
had a goal of 4000$ and raised 7400$).
Indiegogo then takes 4% of the campaign goal (they offer a 25% discount for
non-profit organisations but the conditions that need to be met must be
checked in detail, s. http://www.indiegogo.com/indiegogo-faq), which is
quite a lot of money but if not having to organise everything like credit
card processing, organisation etc. it might be tolerable. The decision of
the copyright holders obviously. I think for many people the deal here is
to trade the advantage of less hassle and a working platform for something
like this for the percentage (much like app stores do for ISVs) and in many
cases theses campaigns would never have happened in the first place in the
absence of such a platform. That's probably why they are so successful.
IANAL but I would expect that it would first have to be agreed upon by the
copyright holders, that the conditions are OK and that the money goes to
ffmpeg (which might then split and redistribute it, I don't know).
There are other minor things like offering people stuff like T-Shirts or
mentioning them on the website as project sponsors if they give money
beyond a certain amount but I don't think this is required.
Btw, I have no business relationship with Indiegogo.

I will go through it as well.
