X-Mailer: Microsoft Outlook IMO, Build 9.0.2416 (9.0.2910.0)

Billy -

I"m happy that you can find my code useful in tvtime.

I do hold the copyrights to those 2 modules mentioned below but choose
to interpret the system & compiler exemption clause somewhat more
liberally.  That is, I think the exemption applies to whatever closed
source tools are needed to compile and run Greedy/HM & TomsMoComp on
your target platform, as long as you don't have source for them anyway.
That is, I don't see it as a problem.

So please take this as my permission to include those two deinterlacing
modules in tvtime, without further obligation other than the terms of
the GPL, as loosely interpreted above.

I also have no problems with LGPL terms if that also becomes necessary
for common sense reasons in some cases, so please contact me again if
that becomes the case or if this email does not seem to give the needed
permissions.

I'm not particularly active on DScaler anymore but would like to
continue to see my code be of value to people.  And while I'm not Linux
literate myself I very much like the idea of my contributions finding a
home there.

Of course, continuing to receive credit would be nice. ;-)

Cheers,

- Tom

|
|   Hey, sorry to bother you.  This email is somewhat long but
| I hope you
| can get through it.  I need a favour.
|
|   I have been using your excellent GreedyH and TomsMoComp
| deinterlacers
| in tvtime under Linux.  It's been great.  Thanks a ton.  They rock.
|
|   However, we've been using them through a Windows emulator DLL loader
| from the Wine project, rather than doing a port.  This is because the
| porting task is somewhat large and I haven't had time to devote to it,
| not because it's impossible (it's not).
|
|   By a strict reading of the GPL though, this is not good.
| Users of GPL
| software need to be given the "complete" source code to build the
| software, with a special exemption for the source to any
| compilers or OS
| pieces you would already need to build software on the target OS.
| However, the target OS for tvtime is Linux, not Windows.  The Windows
| compiler is not a standard Linux tool, so the exemption doesn't apply.
| I would need to ship the full source code to Windows and MSVC++.
|
|   To get around this, we asked John Adcock for an exemption to the GPL
| in this case.  At the time, we were using a bunch of DScaler modules,
| and he asserted that he had copyright over all DScaler plugins.
| However, in our latest version we only use the GreedyH and TomsMoComp
| deinterlacers, both of which were written by you, are independently
| distributed by you, and have your Copyright on them.
|
|   I'm wondering if you'd be willing to extend an exemption to us as
| well.  We've had some discussions on the Debian legal mailing list[1]
| about this, and it's still unclear to me whether this is strictly
| necessary, but it would help us out a lot if you are willing.
|
|   To do so, I think you just have to send me an email like
| the one below
| which we used to have John give us permission.  The original thread
| URL[2] is alsso listed below.
|
|   Thanks, and sorry for the verbosity,
|   -Billy
