High Efficiency Video Coding (HEVC) or H.265 is a quite recent video coding standard which has been ratified in 2013. It can achieve much better rate-distortion performance (and promises 50% bitrate reduction at same subjective video quality) than its predecessor H.264/AVC, which is the dominant video codec currently. However, this performance enhancement comes at the price of a significantly increased encoding complexity.
The « Joint Collaborative Team on Video Coding » has been working on an open-source reference implementation called HM, that can be found on the Fraunhofer HHI website.
On the other hand, probably everybody has heard of the popular x264, an open-source encoder for H.264, which is widely used in various projects, ranging from video software such as ffmpeg to major companies such as YouTube. The success story of x264 had to be continued with HEVC, and thus, the x265 project was started. In order to be able…
