Sažetak
This paper presents Bolt65 HEVC software/hardware suite, consisting of encoder, decoder and transcoder, that is being developed at Faculty of electrical engineering and computing, University of Zagreb. One of the primary focus of Bolt65 is achieving Just- in-Time requirements that would enable video encoding/transcoding on demand. To achieve this goal, Bolt65 tries to maximally utilize all software and hardware components of the system on different architectures, from homogeneous CPU architectures with vector extensions to heterogeneous, accelerator-based architectures that have different types of processing cores. CPU-only implementation of Bolt65 was compared with referent HM HEVC software in three different encoding configurations: All Intra (AI), Low delay (LD) and Random Access (RA). Results show that Bolt65 achieves significant speed-up in all configurations and bitrate savings in AI and RA modes while sacrificing quality in order to achieve just-in-time requirements.
