Bootup automatic process for RMS and CVR with pipewire.

Introduction

This page dedicated to bringing up and validation of RMS and CVR use case with bootup service file.

RMS: 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/RPI-3 device. With RTSP streaming we can able to play live streaming content in VLC player.

CVR: It using pipewire callback to receive frames from v4l2 and also it using AWS Kinesis Video Stream( KVS ) to perform 24/7 video recording with AWS IOT credential.

Build and Flash Procedure

Refer below link to build camera image

Fresh Bootup Setup

STEP 1:

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

network={

ssid="username"

psk="password"

}

ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
update_config=1

network={
ssid="XXXX"
psk="YYYYYYYYY"
}

STEP 2:

AWS Account and IOT credential creation steps

1.AWS account is needed for to validate CVR use case. so, Refer below link to create AWS account.

    Procedure To Create AWS Account

    After the AWS account creation, Refer same link to create Access key ID ,Secret Access Key and Region Name of your AWS account.

2. After the AWS account creation, Need to create IOT credential with AWS CLI interface to validate CVR use case.

Use the below link to install AWS CLI interface package for to create AWS IOT credential.

Please install this AWS CLI package in your local linux pc. we can interact AWS account through our local linux pc with this AWS CLI interface.

https://docs.aws.amazon.com/cli/latest/userguide/install-cliv2-linux.html#cliv2-linux-install

Follow the below command to create config and credentials file in your local PC to interact AWS account

$ aws configure

AWS Access Key ID [None]: XXXXXXXXX	( Give your AWS account Access Key ID )
AWS Secret Access Key [None]: YYYYYYYYYYYYY ( Give your AWS Secret Key )
Default region name [None]: ZZZZZZZZZZ ( Give your Region Name )
Default output format [None]: json

Oncw you done this aws configure in your local PC automatically below files will be create with below content. so, please cross check whether that is created or not

vi ~/.aws/config

[default]
region = ZZZZZZZZZZ
output = json

vi ~/.aws/credentials

[default]
aws_access_key_id = XXXXXXXXX
aws_secret_access_key = YYYYYYYYYYYYY

use the below link to create AWS IOT credential

https://docs.aws.amazon.com/kinesisvideostreams/latest/dg/how-iot.html

After created the IOT credential you will get below list of details

Stream Name, Default Region, IOT Credential Endpoint, Certificate key, Private Kay, Role Alias and cacertificate key

Move the certificate.pem,private.pem.key and cacert.pem keys into your RPI /etc/ssl/certs/ directory

STEP 3:

Copy certificate.pem,private.pem.key and cacert.pem keys into your RPI /etc/ssl/certs/ directory

Give AMS STREAM_NAME,AWS_DEFAULT_REGION,IOT_GET_CREDENTIAL_ENDPOINT and ROLE_ALIAS values in your RPI /usr/local/cvr/cvr.conf file

STEP 4:

Reboot the Target

After Reboot don't do step 1 to 4.

Note : Step 1 to 4 is only applicable for fresh target boot-up with new image.

RMS & CVR Validation

STEP 1:

WiFi/Ethernet connection is must needed for validation

Check WiFi/Ethernet connection by using below command.

ifconfig

root@raspberrypi3-rdk-camera:~# ifconfig

STEP 2:

check loaded module by using below command

lsmod

root@raspberrypi3-rdk-camera:~# lsmod

STEP 3:

check camera device there or not by using below command

ls /dev/video0

root@raspberrypi0-rdk-camera:~# ls /dev/video0 
/dev/video0

STEP 4:

RMS Output

On VLC player, for RTSP streaming

need to enter media → Open Network Stream option and then give rtsp URL to play streaming content in VLC

rtsp://camera_ip:5544/stream2

Example :rtsp://192.168.43.146:5544/stream2

We can able to see the live streaming content on VLC Player.

Note: VLC player available PC and RPI target should run in same network.

STEP 5:

CVR Output

Enter into AWS account and select the corresponding video stream service which was we created for streaming.

Press "Media Playback" option on the video stream player.

Streaming video content should decode properly on AWS.
