Versatile Video Coding (VVC) is the most recent international video coding standard jointly developed by ITU-T and ISO/IEC, which has been finalized in July 2020. VVC allows for significant bit-rate reductions around 50% for the same subjective video quality compared to its predecessor, High Efficiency Video Coding (HEVC). One year after finalization, VVC support in devices and chipsets is still under development, which is aligned with the typical development cycles of new video coding standards. This paper presents open-source software packages that allow building a complete VVC end-to-end toolchain already one year after its finalization. This includes the Fraunhofer HHI VVenC library for fast and efficient VVC encoding as well as HHI's VVdeC library for live decoding. An experimental integration of VVC in the GPAC software tools and FFmpeg media framework allows packaging VVC bitstreams, e.g. encoded with VVenC, in MP4 file format and using DASH for content creation and streaming. The integration of VVdeC allows playback on the receiver. Given these packages, step-by-step tutorials are provided for two possible application scenarios: VVC file encoding plus playback and adaptive streaming with DASH.

适用于通用视频编码 (VVC) 标准的完整端到端开源工具链

通用视频编码 (VVC) 是 ITU-T 和 ISO/IEC 联合开发的最新国际视频编码标准，已于 2020 年 7 月定稿。 VVC 允许在相同主观视频质量的情况下显着降低约 50% 的比特率与其前身高效视频编码 (HEVC) 相比。完成一年后，设备和芯片组中的 VVC 支持仍在开发中，这与新视频编码标准的典型开发周期保持一致。本文介绍了开源软件包，允许在最终确定一年后构建完整的 VVC 端到端工具链。这包括用于快速高效 VVC 编码的 Fraunhofer HHI VVenC 库以及用于实时解码的 HHI 的 VVdeC 库。VVC 在 GPAC 软件工具和 FFmpeg 媒体框架中的实验性集成允许将 VVC 比特流（例如使用 VVenC 编码）打包为 MP4 文件格式，并使用 DASH 进行内容创建和流式传输。VVdeC 的集成允许在接收器上播放。鉴于这些软件包，我们为两种可能的应用场景提供了分步教程：VVC 文件编码加播放和使用 DASH 进行自适应流式传输。
