Subject[PATCH 4/5] media: mediatek: vcodec: Fix bitstream crop information error
Date
Usually, the real bitstream width and height will set to driver
by vidioc_s_fmt, and vidioc_try_fmt() does align to get the
buffer width and height, driver calculate the encoded bitstream
crop information through them. The aligned resolution will be set
as real resolution now if user didn't set crop info by
V4L2_SEL_TGT_CROP, and the encoded bitstream may exist green line
because of crop information error.
