What does the public MPEG V-PCC/V3C reference software (mpeg-pcc-tmc2 release-v25.0) say about its role, build dependencies, how occupancy, geometry and attribute video are encoded, and under what licence?
MPEG's V-PCC reference software (TMC2, release-v25.0) is an experimental reference, not an efficient implementation: it codes a point cloud as separate occupancy, geometry and attribute 2D video streams using external video codecs selected by codecId (JM, HM, VTM, SHM, or FFmpeg on a branch), with stacked configuration files where later files override earlier ones; its test example expects an external MPEG dataset path. The code is under an ISO/IEC BSD-style licence that expressly grants no patent rights, so patent clearance is a separate question.
