Is x265 Royalty Free?
x265 is an open-source implementation of the H.265/HEVC video codec, but it is not entirely royalty-free. While the x265 software itself is free to use, the H.265/HEVC standard is patented by various companies, including MPEG LA, a patent pool that licenses the technology to manufacturers and developers. This means that companies that use x265 in their products or services may still need to pay royalties to MPEG LA or other patent holders.
However, the royalty-free aspect of x265 comes into play when it is used for non-commercial purposes, such as personal video encoding or open-source projects. In these cases, the use of x265 is generally considered royalty-free, as long as the user complies with the terms of the GNU General Public License (GPL) under which x265 is released. Nevertheless, it is essential to note that the licensing landscape surrounding H.265/HEVC is complex, and users should carefully review the terms and conditions before using x265 or any other H.265/HEVC implementation.
What is the difference between x265 and H.265/HEVC?
x265 and H.265/HEVC are often used interchangeably, but they are not exactly the same thing. H.265/HEVC is a video compression standard developed by the Joint Collaborative Team on Video Coding (JCT-VC), a joint committee of the International Telecommunication Union (ITU) and the International Organization for Standardization (ISO). It is a patented technology that is licensed by MPEG LA and other patent holders.
x265, on the other hand, is an open-source software implementation of the H.265/HEVC standard. It is a specific encoder that uses the H.265/HEVC standard to compress video, but it is not the standard itself. x265 is designed to be a highly efficient and flexible encoder that can be used in a variety of applications, from video streaming to Blu-ray disc authoring. While x265 is based on the H.265/HEVC standard, it is not the only implementation of the standard, and other encoders may also be available.
