• 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

•  Playing a video using gstreamer, with gst-launch-1.0.

             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.

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

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.
•        Disable cntlm-main.service if device reboot occasionally.
