Version 7.0 will be released in February. I hope we can include VVC decode.
I also want to give people some time to try and report issues about VVC.
Sending the VVC enabling patch set again may make the filter change

How about I merge this patch set today, and later, my first patch will
focus on fixing this.
I promise I won't make you wait for so long.
Thank you
