looks like you hit a bug in VAAPI, can you try removing that plugins
for now ? Someone should try and see if this is still an issue with
1.16 or master.

I tried it on my KBL machine.

it will get segment fault when use i965 driver.

LIBVA_DRIVER_NAME=i965 ./basic-titorial-7

But it works fine  when use iHD driver. I can see yellow wave in window.

LIBVA_DRIVER_NAME=iHD ./basic-titorial-7

Could you please try:
