  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.
