Introduction

RDK-V IP Client is a IP based Client Set-Top-Box (STB) with RDK 4.0 features which connects directly with Network Gateways. Targets on Accelerator platforms and utilizes only open-sourced RDK components.

Unused components from MediaClient :

IP STB build is based from medicalient image with out the licensed components and other components which are not required for IP streaming. Some of the components which are removed as of now are,

• dvb
• RMF
• ServiceManager
• dvrmgr
• Moca-HAL
• dtcpmgr
• xupnp
• trm

Yocto Build Setup

All RPi based RDK images with the latest features are from the rdk-next branch

Initializing the Build Environment

To build RDK images from ipstb_bringup branch, follow the below build procedure

mkdir workspace
cd workspace

# initialize the manifest with repo tool # initialize the manifest with repo tool
repo init -u https://code.rdkcentral.com/r/rdkcmf/manifests -b rdk-next -m rdkv-extsrc.xml
repo sync  -j `nproc` --no-clone-bundle --no-tags

Image build

MACHINE=raspberrypi-rdk-ipmc source meta-cmf-raspberrypi/setup-environment

bitbake rdk-generic-ipclient-image

Flashing Procedure

The image file will be generated under build-<MACHINE>/tmp/deploy/images/<MACHINE> directory.

eg: $ pwd

build-raspberrypi-rdk-ipmc/tmp/deploy/images/raspberrypi-rdk-ipmc

$ ls -lrt rdk-generic-ip-stb-client_rdk-next_20210914060227.rootfs.rpi-sdimg

-rw-r--r-- 2 dsrava434 dsrava434 478150656 Sep 13 12:33 rdk-generic-ip-stb-client_rdk-next_20210914060227.rootfs.rpi-sdimg

build-raspberrypi-rdk-ipmc/tmp/deploy/images/raspberrypi-rdk-ipmc$ 

For flashing the image use dd command.

eg:   sudo dd if=rdk-generic-ip-stb-client_rdk-next_20210914060227.rootfs.rpi-sdimg of=/dev/sdb bs=4M

Testing Procedure

•  Controller UI : For connecting Controller UI, use URL: http://<machineip>:9998

• Enabling / Disabling the Plugins from controller UI. 

• Wi-Fi Services: Wifi related services can be triggered from Wi-Fi tab in controller UI. We can scan and select from available networks.

• R-Pi Board Console Access : Execute ssh root@machineip from your host PC
• Image Details Verification: For verifying the image details, we can use cat /version.txt command.     

•  Playing a video using gstreamer, with aamp as gstreamer plugin element by using aamp:// in the uri:

  eg :- gst-launch-1.0 playbin uri=aamp://bitdash-a.akamaihd.net/content/MI201109210084_1/m3u8s/f08e80da-bf1d-4e3d-8899-f0f6155f6efa.m3u8 video-sink=westerossink

• Playback through Youtube Application : For launching youtube from controller UI, enable cobalt plugin, youtube page will be loaded in TV UI.

• Youtube Launched Output in the TV:

• Youtube Launching Via Resident App: To load Youtube from Resident app UI, select Premium content 1 and press enter

• Once entered the premium content1, Youtube page will be loaded.

• Select and press enter to begin the playback.

• To return to main menu, press cntl+m or home button.

Cobalt lifecycle using terminal:

Launching cobalt using RDK Shell : execute below command from ssh terminal

   curl --data-binary '{"jsonrpc":"2.0", "id":3, "method":"org.rdk.RDKShell.1.launch", "params":{"callsign": "Cobalt", "type":"", "uri":""}}' -H 'content-type:text/plain;' http://127.0.0.1:9998/jsonrpc

 Setting a video URL using deeplink method.

    curl --data-binary '{"jsonrpc":"2.0", "id":3, "method":"Cobalt.1.deeplink","params": "<videoURL>"}' -H 'content-type:text/plain;' http://127.0.0.1:9998/jsonrpc

Sending enter key to proceed video playback

    curl --header "Content-Type: application/json" --request POST --data '{"jsonrpc":"2.0", "id":3, "method":"org.rdk.RDKShell.1.generateKey", "params":{"keys":[ {"keyCode": 13,"modifiers": [],"delay":1.0}]}}' http://127.0.0.1:9998/jsonrpc

Suspending the plugin using RDKShell

   curl --data-binary '{"jsonrpc":"2.0", "id":3, "method":"org.rdk.RDKShell.1.suspend", "params":{"callsign": "Cobalt"}}' -H 'content-type:text/plain;' http://127.0.0.1:9998/jsonrpc

Resuming the plugin

   curl --data-binary '{"jsonrpc":"2.0", "id":3, "method":"org.rdk.RDKShell.1.launch", "params":{"callsign": "Cobalt", "type":"", "uri":""}}' -H 'content-type:text/plain;' http://127.0.0.1:9998/jsonrpc

Known Issues

Trouble Shooting

• Overcoming build time fetch errors: 
  • If fetch failure occurs for libinput, comment SRC_URI related changes from meta-cmf/recipes-graphics/libinput/libinput_git.bbappend.
  • If fetch failure occurs for gst-plugins-ugly,use mirror source, for that comment out SRC_URI related changes from meta-cmf/recipes-multimedia/gstreamer/gstreamer1.0-plugins-ugly_git.bbappend.    
•  If the wireless networks are not listed in controller wifi page, try after disabling and enabling wifi from Network page, networks will be listed.
