Toward Faster HEVC for Video Conference Applications
2019
The exhaustive search performed by the HEVC encoder makes the encoding process very slow. Video conferencing is highly used nowadays and this kind of videos requires very fast encoding for real-time transmission. In this paper, we propose two early termination algorithms that accelerate the encoding process with a negligible effect on the compression efficiency for video conference sequences. The first algorithm makes use of stable background that appears in the scene for a long period of time. The second algorithm makes use of wide spaces of one color that happens in videos with text and graphics, which are frequently found in video conference applications. The results show that our algorithms accelerate encoding of video conference sequences by an average of 22.19% with a negligible effect on the compression efficiency.
