Intel officially ends development on SVT-HEVC open-source video encoder project

On August 23, Intel announced it has ceased development and contributions to the SVT-HEVC open-source video encoder project, part of its Scalable Video Technology (SVT) initiative. This decision means Intel will no longer maintain, fix bugs, release new versions or updates, or accept any patch submissions for the project.

SVT-HEVC is a high-performance H.265/HEVC video encoder under the BSD license that gained recognition for its optimization for Intel Xeon Scalable processors and Intel Xeon D processors since its launch. The project aimed to drive innovation and development in video transmission, processing, and analysis by providing efficient video encoding solutions. However, with technological advancements and evolving market demands, Intel decided to adjust its video encoding technology research and development direction, ultimately leading to the termination of the SVT-HEVC project.

Intel's official announcement reveals that the SVT-HEVC project hasn't released any new versions since 2021. As time went on, the SVT-HEVC repository on GitHub became read-only, marking the official halt of development and maintenance.

The termination of the SVT-HEVC project has sparked mixed reactions within the industry and the open-source community. Some argue that SVT-HEVC, as a high-performance video encoder, will cause inconvenience to certain users after its cessation. Others point out that with the emergence of other excellent open-source H.265 encoders such as x265 and Kvazaar, the end of SVT-HEVC does not signify stagnation in video encoding technology.

The reasons behind Intel's decision to stop developing SVT-HEVC could be multifaceted. In recent years, rapid advancements in video encoding technology have led to the emergence of new encoding standards and algorithms like AV1 and VP9. These new technologies surpass H.265 in terms of coding efficiency and compression ratio, prompting Intel to potentially reallocate resources towards research and development of these new technologies to maintain its competitive edge in the video encoding field.

Furthermore, the active open-source community has also played a role in Intel's decision. The number of open-source video encoders has been steadily increasing, and their performance often rivals Intel's SVT-HEVC. This has raised concerns about the return on investment for Intel in continuing to invest resources in developing and maintaining the SVT-HEVC project.

Despite Intel's discontinuation of the SVT-HEVC project, the accumulated technology and experience from the project remain significant for the future development of video encoding technology. The techniques and algorithms utilized in the SVT-HEVC project, such as adaptive quantization, motion estimation, and intra-prediction, have served as valuable references for the development of other video encoders. Moreover, the project's termination creates a wider scope for other open-source video encoders to flourish.

Intel's decision to stop developing SVT-HEVC reflects a strategic adjustment in their video encoding technology realm and mirrors the broader trends in the open-source community and the progress of video encoding technology. In the future, with continuous advancements, video encoding technology will become more efficient, reliable, and flexible, delivering enhanced video experiences for users.
