Introduction

The RDK Media Streamer is much more than a multi-format, multi-protocol server that delivers your media rich content across multiple screens and platforms. The RDK camera software runs on RPi-0 device. This page dedicated to bringing up and validation of RMS functionality in R-Pi Zero. 

Required Equipment

  • Raspberry Pi 0 Device
  • SD Card
  • Power Cable
  • OTG Cable
  • Standard USB keyboard
  • Mini HDMI connector
  • HDMI Cable
  • Television set/monitor with HDMI input

RMS Validation Procedure

STEP 1:

Add require SSID and PSK in /etc/wpa_supplicant.conf file in below format

...

ssid="username"

psk="password"

}Image Removed

Code Block
languagebash
titleConsole output
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
update_config=1

network={
ssid="RDK"
psk="Comcast1"
}


STEP 2:

Reboot the Target

After Reboot don't do step 1 and 2.

...

Modify needed resolution in ems rms configuration file

Supported Resolution:

...

Modify resolution in below configuration file

cd /usr/binlocal/evorms/bin

vi emsrms.confImage Removed

Code Block
languagebash
titleConsole output
RRSIP=18.224.54.11
RRSPORT=81
ROOMID=rpi0
RRSSSL=0
WIDTH=1280
HEIGHT=72

After resolution modification need to reboot the target.

...

WiFi connection is must needed for EMS RMS validation.

Check WiFi connection by using below command.
