I've run this serie on SM8650-HDK, and all test works (+ visually confirmed)
except the rotate90 & rotate270 which fails with:
[  113.494611] qcom-iris aa00000.video-codec: session error received 0x1000005: unknown
printed on dmesg.

Do you know if those operations are supposed to work on the sm8650 hw & fw ?
