The problem with that is that it tends to add size to some encodes.

I encoded a 3 minute sample of content I knew would produce the seeking issue, despite auto-alt-ref. First with -g 250, then without. All else the same.

The gop set file is 30,979,544 bytes.
The file without gop set is 28,246,134 bytes.

Not much, but there's still a difference. So I guess bigger file size is the price for guaranteeing some kind of quick seek.

Be that as it may, with or without gop, auto-alt-ref still helps a lot in most videos, and this makes vp9 more usable for my purposes.
