Abstract
In this paper the complexity of the JVET encoder is analyzed. JVET is the joint video exploration team of ITU-T VCEG and ISO/IEC MPEG to explore new ways in video coding to improve HEVC/H.265 standard. Currently, JEM 7, the JVET reference software, is able to compress 30% better than HM, the HEVC reference software but its computational complexity is considerably higher than HM. By profiling function calls, time consuming functions in different encoding scenarios are analyzed and reported. It is observed that the upcoming standard could increase the complexity by up to 20 times compared to the current HEVC standard, if no optimization is considered. The contribution of each function is detailed and analyzed. The complexity is mostly attributed to the new intra-coding functions and new transform coding.
