You should split this into two patches, one the w32pthreads C++ support, 
other the decklink patch.

Also, I checked the decklink part, and I am a bit confused. I don't see 
how you ensure that ctx->frames_buffer number of frames are scheduled. 
Also, are you sure you use the condition/mutexes properly? Your code does 
not even contains a pthread_mutex_lock call, that seems odd.

What I would expect is to protect the scheduled frame counter with a 
mutex, and do a cond_signal in the scheduled frame completed callback. Or 
do you have something else in mind?
