from documentation i learn that i should use a CVPixelBufferPool when
i want to further process (e.g. record) CVPixelBuffers,
but can you share a CVPixelBufferPool between threads? and pass
CVPixelbuffers from one thread to the other?
and also, the displaylink-callback is already called from a seperate
(high-priority) thread.

If neither docs nor headers say that an API is thread safe you should assume it is not.
It might be safe to make serialized calls using the CVPixelBuffer(Pool) API using a lock.
