Subject: [PATCH v2 17/18] media: mtk-vcodec: venc: set default time per frame
Date: Fri, 26 Jun 2020 17:04:41 +0900
Message-ID: <20200626080442.292309-18-acourbot@chromium.org> (raw)
In-Reply-To: <20200626080442.292309-1-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.
