Comment:

 Can reproduce this issue with commit 9326117bf6.
 This is a multithread issue, if set "thread=1" then the error dispears:
 ffmpeg -y -hwaccel vaapi -hwaccel_output_format vaapi -threads 1 -i /fate-
 suite/vp8/dash_video4.webm -frames 250 -f null -

 a iHD driver issue has been created to check it, as the same time there
 was a ffmpeg patch to fix it(https://patchwork.ffmpeg.org/patch/9943/) but
 still not merged.
