Subject: [PATCH v3 15/16] media: mtk-vcodec: venc: set default time per frame
Date: Mon, 13 Jul 2020 15:08:41 +0900 [thread overview]
Message-ID: <20200713060842.471356-16-acourbot@chromium.org> (raw)
In-Reply-To: <20200713060842.471356-1-acourbot@chromium.org>
The time per frame was left initialized to 0/0, which make the driver
fail v4l2-compliance, and also leaves it potentially exposed to doing a
division by zero.
