Thanks for explanation about video delay on LAV CUVID decoder. I think I need to try another decoders.
every video I play has a fixed "0/18" buffer back/ahead, is it ok?
It is OK. Your CPU have 8 logical cores. For 8 cores SVP needs 15 threads. In hidden settings placed number of extra frames in buffer. It is 3. And finally you get 15+3 = 18 frames ahead when Threads number set to auto.
I check it on my system. It is no difference between 1 and 18 frames ahead. And I leave this number untouched. It looks like optimization inside ffdShow with frame number correction by threads count. No longer need to point real number. Just zero or not zero.
Try to play 60fps video with SVP enabled. Just this case was fixed.
