uvgVPCCenc: Practical Open-Source Encoder for Fast V-PCC Compression
Year: 2025
Type: conference-paper
Abstract: Video-based Point Cloud Compression (V-PCC) standard offers state-of-the-art tools and efficiency for volumetric video compression. The V-PCC reference software, TMC2, is able to demonstrate the compression efficiency of V-PCC, but with computational complexity that is impractical for real-life applications. This paper introduces a novel open-source V-PCC encoder, named uvgVPCCenc, that brings V-PCC compression speed to a practical level. To reduce computational bottlenecks, uvgVPCCenc is implemented from the ground up in C++ with advanced multi-threading and streamlined algorithms. It also supports a flexible parameterization and different presets that facilitate its adaptation to various content and target bitrates. Our comparative evaluations show that uvgVPCCenc achieves substantial speedups over TMC2 while maintaining competitive rate-distortion-complexity tradeoff. To the best of our knowledge, uvgVPCCenc is the first open-source encoder explicitly designed for practical V-PCC compression, paving the way from theoretical research to practical volumetric video applications.
