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 is dedicated for RPI-0 setup with camera,Build Instruction and Testing procedure for camera features.dedicated to bringing up and validation of RMS functionality in R-Pi Zero.

EMS - EvoStream Media Server

The EvoStream Media Server is much more than a multi-format, multi-protocol server that delivers your media rich content across multiple screens and platforms.

Test Procedure

...

Image Flash Procedure

Code Block

language	bash
title	Image 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

...

ssid="username"

psk="password"

}Image Removed

Code Block

language	bash
title	Console 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:

Get WiFi IP by using below command

udhcpc -i wlan0

Image Removed

STEP 4:

Connect RPI-0 device with WiFi Ip

ssh root@WiFI_IP

for Ex: ssh root@192.168.2.7

Image Removed

STEP 5:

This modprobe command is used to load v4l2 module in RPI-0 device.

modprobe bcm2835-v4l2

Image Removed

STEP 6:

check loaded module by using below command

lsmod

Image Removed

STEP 7:

check camera device there or not by using below command

ls /dev/video0

Image Removed

STEP 8:

export LD_PRELOAD=/usr/lib/libwayland-client.so.0:/usr/lib/libwayland-egl.so:/usr/lib/libopenmaxil.so

Image Removed

STEP 9:

Run mediastreamer in background

mediastreamer &

Image Removed

Some prints are coming after run mediastreamer,After that print just give ENTER button and the terminal will come back.

STEP 10:

Run Evostreamms in background

cd /usr/bin/evo/bin

./evostreamms ../config/config.lua &

Image Removed

Some prints are coming after run evostreamms,After that print just give ENTER button and the terminal will come back.

STEP 11:

check the mediastreamer and evostreamms are running or not by using below command

jobs

Image Removed

STEP 12:

Connect ASCII CLI Interface at EMS by using below command

Telnet localhost 1222

Image Removed

STEP 13:

Check available configuration in telnet console by using below command

listconfig

Follow from step 14 continuously when you got listconfig like below snap.

Image Removed

Follow from step 15 continuously when you got listconfig like below snap.

Image Removed

Follow step 17 only when you got listconfig like below.

Image Removed

STEP 14:

Do the pull stream in telnet console.

Pullstream uri=sercom://0 localstreamname=stream2

Image Removed

STEP 15:

start webstc in Telnet console.

Startwebrtc ers=community.dummyers.server.com ersport=81 roomid=rpi0 ersOverSsl=0

Image Removed

STEP 16:

Check whether the pullstream and webrtc are properly added or not in EMS by using below command

listconfig

Image Removed

:

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

language	bash
title	Console 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
