In this work we evaluate the implementation of a video encoder based on the 3D Wavelet Transform optimized for HyperThreading technology and SMPs. We design several implementations of the parallel encoder with Pthreads and OpenMP using functional decomposition. Then, we compare them in terms of execution speed, ease of implementation and maintainability of the resulting code. Our experiments show that while Pthreads provides the best results in terms of execution time, OpenMP can provide a nearly optimal execution time without sacrificing the maintainability of code.
