Subject: [PATCH] media: venus: change the default value of GOP size
Date:   Mon, 12 Nov 2018 14:36:02 +0530
Message-Id: <1542013562-18968-1-git-send-email-mgottam@codeaurora.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

When the client doesn't explicitly set any GOP size, current
default value is low and overshoots bitrate beyond  tolerance.
Hence default value is modified so as to have intra period of 1sec.
