Tried. No change.

I later managed to more narrow down the issue. Its the vp9 file itself having an issue. Many video packets having negative PTS values!

I presume the issue is libvpx-git is not ready yet. I'll check with webm project what options currently can be used. The libvpx 1.3.0 for vp9 is no use. Way too slow.
