Subject: [PATCH 2/4] venus: update calculation for dpb buffers
Date:   Thu,  4 May 2023 16:06:37 +0530
Message-Id: <1683196599-3730-3-git-send-email-quic_dikshita@quicinc.com>
In-Reply-To: <1683196599-3730-1-git-send-email-quic_dikshita@quicinc.com>
References: <1683196599-3730-1-git-send-email-quic_dikshita@quicinc.com>
Precedence: bulk

Use dpb color format, width and height of output port
for calculating buffer size of dpb buffers.
