VaapiVideoDecodeAccelerator seems to get by without explicitly dlopen()-ing
here.  Can you look into how they do it?

[shivdasp, 2014/03/24 06:01:27]

It seems VaapiVDA is using some auto-gen mechanism to avoid the dlopen().
I am trying to understand it more but I am afraid might run into x86 only
scripts.
Do you have any pointers on how this autogen stuff works ? It might help me to
do the change quicker.
