This demonstrator presents a run-time visualization tool for Kvazaar HEVC intra encoder. The implemented open-source tool is seamlessly integrated into Kvazaar to provide instant visual feedback of the encoding process. The visualization overlays the reconstructed HEVC video with the boundaries of the used block partitioning structure and associated intra prediction modes. The tool is also able to illustrate all Kvazaar parallelization schemes at run time: Wavefront Parallel Processing, tiles, and picture-level parallel processing. The displayed visualization information can be gradually adjusted to user needs. The tool is primarily designed for Kvazaar debugging but it also suits educational purposes.
