Platform Team :

  • Generated core minimal image using the recipe rdk-geneirc-camera-img.bb
  • Analysis on RDK-C manifest and listed out the recipes need to be written and available ones
  • Planned to have validation using userland utilities like raspistil, raspivid etc
  • Also would like to valid the streaming use cases with gst-launch utilities with v4l2 src and glimage sinks etc

RDK-C Team :

  • Working on the Yocto recipes for the SoC SDK with minimal boot core image with external toolchains
  • Suggesting for the streaming use cases for first validation along with basic features such as Webpa

RDK-M Team :

  • Need to work along with Revathy on the meta layers for proposing the changes on recipes
  • Raj to come up with road-map plan for covering the features
  • As of now comcast JIRA is used for epic story ticket and in RDK wiki we shall have restricted page within the RDK-M and Comcast-RDK-C team

Introduction

The RDKC Media Server 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. 

Environment Setup

Please refer below link for RPI-0 Environment setup

Build Procedure

Refer below link to build camera image

RDK-C Build Instruction for RPI-0

Image Flash Procedure

Code Block
languagebash
titleImage Flash step
$ sudo dd if="Image Name" of="Device Name" bs=4M

Example:
sudo dd if=rdk-generic-camera-image_default_20200130060729.rootfs.rpi-sdimg of=/dev/sdb bs=4M

RMS Validation Procedure

STEP 1:

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

network={

ssid="username"

psk="password"

}

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.

Note : Step 1 & 2 is only applicable for fresh target boot-up with new image.


STEP 3:

Modify needed resolution in rms configuration file

Supported Resolution:

SD:

Width - 640 , Height - 480

Width - 720 , Height - 576

HD:

Width - 1280 , Height - 720

FULL HD  :

Width - 1920 , Height - 1080


Modify resolution in below configuration file

cd /usr/local/rms/bin

vi rms.conf

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.

Note: This step is not necessary,it is depends on your resolution validation.


STEP 4:

WiFi connection is must needed for RMS validation.

Check WiFi connection by using below command.

ifconfig

Code Block
languagebash
titleConsole output

STEP 5:

check loaded module by using below command

lsmod
