Introduction

This manual describes the rdk-generic-mediaclient-image build procedure for describes  Yocto 3.1 buildsbuild procedure for Raspberry Pi Reference Platform. This will upgrade the default build system used in RDK Video, from morty(2.2) to dunfell(3.1). In addition to upgrades to opensource packages, Yocto 3.1 also contain Long term Support release feature. The current version lacks the variety of features available in the dunfell. The upgraded build tools will be used to generate rdk-generic-mc-image for Raspberrypi reference platformdifferent images for the target. 

Yocto 3.1 Upgradation support the following:

• Yocto BSP layer for meta-raspberrypi.
• OpenEmbedded and Yocto Dunfell.
• Linux kernel 4.19.
• Version upgrades for bitbake, gstreamer and other oe/wpe recipes.
• Playing a given stream using gst-launch command.
• rmfApp Support.
• Controlling apps using appmanager.

Each component in RDK is a standalone repository with its own individual build tools producing a library or set of binaries. When we upgrade the OE layers to the newer versions, we need to make necessary changes in the RDK layers which use these components, to avoid build failures.
