The biggest problem is those companies within the group don't agree on the percentage spilt between them. Basically they are just being bloody greedy. And the reason why we have MPEG-LA, HEVC Advance, Velos Group and others.
The good things is that most companies realise how much of a poor job MPEG-LA did ( My guess is that they only cares about their commission any way ), they started MC-IF , which includes most of the original HEVC MPEG-LA Group members, HEVC Advance Members and one Velos members as well. They are basically most of the Japanese players... and ...... Qualcomm.
I really wish VVC succeed, and push the technical limits of Video Compression as well as replacement of JPEG, without all the dramas and patents problems.
