I suspect a regression in the driver regarding quality level.
Current default of quality level is 4 and it results in poor quality.
If I set 1(the highest quality) to quality-level in vaapih264enc, its quality
gets better. But still not statisfied the PASS standard.
And I revert the commit 481ec15[1] in the driver, the quality is much better to
get passed enough.
IMO, someone in the intel driver should look into this.
