A new video coding standard, Versatile Video Coding (VVC), will be finished in July 2020 by the Joint Video Experts Team (JVET). The group of JVET is a joint initiative between the ITU-T Video Coding Experts Group (VCEG) and the ISO/IEC Moving Picture Experts Group (MPEG). The VVC is the successor to the High-Efficiency Video Coding (HEVC) standard, and ITU-T will release it as H.266 and by ISO/IEC as MPEG-I Part 3 (ISO/IEC 23090-3).
The new standard aims to achieve the same level of visual quality as HEVC while reducing the bit rate by fifty percent. In addition, VVC demonstrates its true versatility by including tools for the efficient coding of video content in emerging applications such as high dynamic range (HDR), adaptive streaming, and computer-generated content, as well as immersive applications such as 360-degree video and augmented reality. This allows VVC to support a wide range of use cases (AR).
During the standardization process, the VVC test model (VTM) acts as a standard reference implementation, also known as a test bed, to evaluate and verify various proposed technologies. In the past, VTM was the only encoder and decoder implementation of the VVC standard that was publicly available. However, because it is focused on correctness, completeness, and readability, it should not be used as a real-world example of a VVC encoder and decoder. Instead, it should be considered an implementation of the standard.
A Quick Look at the Features Of Vvenc
Vvenc is the encoder implementation that is simple to use and comes with five predetermined quality/speed presets.”Below mentioned are some features of vvenc.
- A VVC encoder has been optimized to provide speedups of between 5x and 390x over VTM-11.0 for HD and UHD test sequences. Of course, the speedup depends on the quality/speed preset that is chosen.
- Optimization of perceptions raises the viewer’s impression of the video’s overall quality.
- Frame-level rate control supporting VBR encoding.
- The Encoder interface is accessible in an expert mode, which enables fine-grained control of the encoding process.
How to build vvenc ?
The main aim of vvenc is to generate platform-specific build files for the product. To construct the software, you will need an operational CMake installation. Installing CMake requires downloading it from the website http://www.cmake.org/. Read on the entire blog to understand more about vvenc.
What are the steps to building for vvenc?
It is necessary to have Visual Studio 2017 or a later version, as well as CMake Version 3.12 or the last version, in order to compile the software for Windows. You should install gnuwin32, which will provide a make-for Windows. To build the software, open a new command prompt window, go to the directory where the project is stored, and type:
Make an install-release
Once this process is completed, the statically linked release version of the encoder apps will be created and placed in the install/bin/release-static/subdirectory. Now this is for the Windows and Android, So the question arises How to construct vvenc for Linux and MacOS?
Compiling the software for Linux requires GCC version 7.0 or above and CMake version 3.12 or higher. Both of these requirements must be met. For MacOS, you will need Xcode Version 3.12 or above and CMake Version 3.12 or higher. It is possible to use a Makefile with predefined targets to streamline the building process. For example, to make the VVenC encoder apps, open a terminal, go to the directory where the project is stored, and type the following commands.
Make an install-release of vvenc
Once this process is completed, the statically linked release version of the encoder apps will be created and placed in the install/bin/release-static/subdirectory.
Variations on the Theme of VVENC
- MOVID Video Converter
Movavi Video Converter is a platform that allows for the encoding, compression, and conversion of video that can be downloaded for free. Users can convert videos into more than 180 different formats. It also has capabilities that allow users to add subtitles to videos and do a few other video editing activities, such as cutting and combining multiple videos.
Exceptional qualities include:
- Because of the increased conversion speed, file compression is straightforward.
- Videos used in education are made even more accessible with the help of animated arrows.
- DivX Converter
The video-encoding program, DivX Converter, is available for free download, but it has tiered pricing for consumers requiring numerous licenses. Users can make backup copies of DVDs and convert videos on various devices using this software, which is compatible with Mac and PC operating systems. Pricing begins at $19.99 for a license that covers 2–10 users.
Exceptional qualities include:
- The technology of dragging and dropping allows users to encode videos with relative ease.
VideoProc
VideoProc is a video converter and editor that is compatible with Windows. The program is available for free download, and users have the option to pay for additional features. It is consistent with the most widely used file formats, and many users find it straightforward to use. However, some things can’t be done with the free version, and some people have said that the download speeds aren’t very good.
Exceptional qualities include:
- Provides customers with a complete graphics processing unit, which makes it easy for them to edit and convert content.
- Even the ambient sounds can be adjusted by the users.
Conclusion
The Versatile Video Encoder (vvenc) from Fraunhofer is a real-world VVC encoder solution that is both quick and efficient. Its primary characteristics are as follows: There is a user interface provided for the expert mode encoder, which enables fine-grained control of the encoding process. The VVC encoder has been optimized to give speedups of between 18x and 1500x over VTM-17.2 for HD and UHD test sequences, with the speedup varying depending on the quality/speed setting that is selected. The whitepaper on VVenC has additional information on where to get it, how to access it, how to develop it, how to use it, and how well it performs.
