If a mod includes code from ffmpeg then it's a derivative work, and you have to make the whole of the work (the mod) available as source code - as you said. Not only is our mod a closed source mod, but modders dont have the right to redistribute the modified SDK code - which would have to be included. This is why they are incompatible.
As modders, we dont own the SDK code, so it's not our place to agree to the terms of the GPL or LGPL. Valve would have to grant us permission to do so. > Date: Mon, 22 Mar 2010 00:32:27 +0100 > From: [email protected] > To: [email protected] > Subject: Re: [hlcoders] Showing live action videos as TV Commercials > > Brent Lewis wrote: > > Just realized that I can't use it. ffmpeg is GPL, and is not > > compatible with the license for Source SDK.
