Quote: "Well, INAL, but section §52 of the European Patent Convention excludes programs for computers from being patented. Mind you, the UK (where Game Creators are based) aren't going to be part of the EU after March 2019.... "
They use the "Verfahrenspatent" (=process patent?) or the "Geschmacksmuster" (=design patent?) to get patents on algorythms.
They are so creepy, even if you create a superior algorythm totally diffrent, that can also give the same calculation results, they try to shut you up if they see their money in danger. (At least when you are working in my jungle) As I said, It does not have to be true, to get you into a defense position. Once you are there be pepared to pay about 10000€, just to say: "Nope, this is bullshit."
Code is logical, law isn't.
Libav is still a very interesting lib. I searched recently for video libs, but I have not found this one , thx btw
The GPL licence is well described in the FAQ. I do not see any problems here.
