x265 HEVC Encoder
UHDkit Encoding Library
UHDcode HEVC Decoder
Accelerated VP9 Decoding
x265 is based on the x264 codec (widely recognized as the highest quality H.264 codec implementation), and the command-line syntax and feature set are similar. x265 is by far the most widely used HEVC (H.265) encoder in the world, powering the H.265 encoding capabilities of many leading open source applications including FFMPEG and VLC. Widespread usage, combined with the collaborative open source development model helped create a robust implementation compared to proprietary H.265 encoders.
x265 is the gold standard in HEVC encoding. It is used by leading video streaming services, movie studios, post production facilities, video system developers and software developers worldwide. x265 is licensed by more than a dozen leading commercial broadcast and web video encoding system vendors including Telestream, BBright, Sorenson Media, Pegasys, and Capella Systems.
