[PATCH v6 14/18] media: verisilicon: vp9: Use destination buffer height to compute chroma offset
From: Benjamin Gaignard <benjamin.gaignard@collabora.com>
Date: 2023-09-01 12:44:53
Also in:
linux-arm-msm, linux-media, linux-mediatek, linux-rockchip, linux-staging, lkml
Subsystem:
hantro vpu codec driver, media input infrastructure (v4l/dvb), the rest · Maintainers:
Nicolas Dufresne, Benjamin Gaignard, Philipp Zabel, Mauro Carvalho Chehab, Linus Torvalds
Source and destination buffer height may not be the same because
alignment constraint are different.
Use destination height to compute chroma offset because we target
this buffer as hardware output.
