Enable GPU accelleration by default

[GoogleCodeExporter]

On a fresh installation a user has to manually select their GPU accelleration 
setting. This can be confusing for certain users who then find LAV not working 
as well as their 'other' solution.

So it is perhaps possible to do a DirectX feature scan and enable at least 
"DVXA2 (Native)" if a videocard with support is found?

Any advanced user who wants to use custom processing filters will know to then 
adjust this setting to (copy-back), or switch to CUVID or Quick Sync for their 
preference.

The default "None" is just a killer on first time LAV experience when the user 
is less experienced.

Same goes for audio, perhaps after install some sort of "wizard" can be 
activated (or skipped for the advanced user) that plays back small audio sample 
files for AC3, DTS, DTS-HD, etc and a user can simply press yes/no on the "Did 
you hear this sound play?".

I want to recommend LAV more to people, but unless I can control their system 
and configure it for them, then the less experienced user always reply with a 
negative experience.

If user knows what GPU acceleration is, or that he realises that he uses LAV at 
all (and not some mysterious software that he beloved codeck pack installed for 
him), he should be smart enough to be able to select it from simple dropdown 
menu. For those who don't know what is this, software is the best option as 
they wont be able to notice any difference anyway. What experience you talking 
about? omg...
Audio: nice joke.

If you recommend it to people - don't say how good GPU decoding is, or 
something else. Tell just to install and don't muck with options unless they 
know what they do. LAV's defaults works just fine.

I have considered adding a simple checkbox into the installer which says 
something like "Use Hardware Accelerated Decoding" so people can check that 
instead of opening the options panel, but not sure how it would work yet 
exactly.

I'll re-visit this idea at a later time.
For now i'm fine with people just grabbing a codec pack or reading a guide 
which walks them through the setup, if they do not know how to do it themself.

The Audio thing will probably never happen. ;)
