Subject: [PATCH v5,1/6] media: mtk-vcodec: venc: remove redundant code
Date:   Sat, 5 Jun 2021 10:29:13 +0800

vidioc_try_fmt() does clamp height and width when called on the OUTPUT
queue, so clamping them prior to calling this function is redundant. Set
the queue's parameters after calling vidioc_try_fmt() so we can use the
values it computed.
