Sigh. In principles, b_thread_safe_callbacks means that get_buffer2 (so Get()) 
is thread-safe. Release() should always be thread-safe.

In practice, b_thread_safe_callbacks is always true because HAVE_AVCODEC_MT is 
always defined, because FF_THREAD_FRAME is always defined.

So the if-statement is useless and confusing at best.
