[PATCH 2/2] media: imx: imx7-media-csi: Fix applying format constraints

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



v4l_bound_align_image aligns to a multiple power of 2 of walign, but the
result only needs to be a multiple of walign. Fix this by using
v4l2_apply_frmsize_constraints() instead.

Tim,
can you please test if this fixes your problem?
Apparently this issue only arises under specific conditions, e.g. 640/480/8bpp.
This issue does not show up for 640/480/10bpp.
