The library uses List<byte> buffers and I believe the List<T> default constructor only allocates enough space for 10 entries. Given the size of MMAL buffers and camera frames, we should investigate whether there is any benefit to allocating a much larger size in the constructor.
Edit: Additionally, the default behavior is to double the capacity each time the limit is reached. Each list potentially allocates up to twice as much memory as it actually needs.
