HEVC codecs will replace H.264 ones inside the consumer electronic devices in the near future. In this work, the open source OpenHEVC decoder has been modified in order to support parallel decoding at the slice level using OpenMP instead of pthreads. The advantage of this unthreaded decoder is that it can be used with any architecture, providing it supports OpenMP. Tests have been carried out with three different multicore chips and the performance results are similar to those obtained with the pthreaded OpenHEVC decoder.
