Introduction
This page dedicated to bringing up and validation of Continuous video recording functionality in RPI 3B+ target.
CVR uses Kinesis Video Streams and supporting 24/7 video recording support.Allows the feature of storing the recorded content AWS server.
Build Procedure
Refer below link to build camera image
RDK-C Build Instruction for RPI-3
Image Flash Procedure
$ 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
AWS Account creation steps
STEP 1:
Can't able to validate without AWS account. so,Refer below link to create AWS account.
Procedure To Create AWS Account
After AWS account creation ,Refer same link to create Access key ID ,Secret Access Key and Region Name.
STEP 2:
Follow below steps to create kinese video stream or refer below link.
https://docs.aws.amazon.com/kinesisvideostreams/latest/dg/gs-createstream.html
1.Sign in to the AWS Management Console and open the Kinesis console at https://eu-west-1.console.aws.amazon.com/kinesisvideo/home?region=eu-west-1#/.
2.On the Video streams page, choose Create video stream.
3.On the Create a new video stream page, type ExampleStream for the stream name. Leave the Default configuration radio button selected.
4.Choose Create video stream.
5.After Kinesis Video Streams creates the stream, review the details on the ExampleStream page.
CVR Validation Procedure
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="XXX"
psk="YYYY"
}
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:
WiFi connection is must needed for CVR-AWS validation.
Check WiFi connection by using below command.
ifconfig

STEP 4:
Export Created Stream Name,Access key id, Secret access key and Region name in RPI target.
export STREAM_NAME="samplestream"
export ACCESS_KEY="XXXXXXXXXXXXXX"
export SECRET_KEY="yyyyyyyyyyyyyyyyyyyyyyyy"
export AWS_DEFAULT_REGION="eu-west-1"
root@raspberrypi3-rdk-camera:~# export STREAM_NAME="Samplestream"
root@raspberrypi3-rdk-camera:~# export ACCESS_KEY="XXXXXXXXXXXXX"
root@raspberrypi3-rdk-camera:~# export SECRET_KEY="yyyyyyyyyyyyyyyyyyyyyyyyy"
root@raspberrypi3-rdk-camera:~# export AWS_DEFAULT_REGION="eu-west-1"
STEP 5:
Check exported Access key id,Secret access key,Stream name and Region name by using below command.
printenv
root@raspberrypi3-rdk-camera:~# printenv
PLAYERSINKBIN_USE_WESTEROSSINK=1
WAYLAND_DISPLAY=wayland-0

STEP 6:
Before triggering CVR binary we should stop rms binary and mediastreamer binary with below command because currently we can't able to validate RMS and CVR feature at the same time.
systemctl stop rms-launcher
systemctl stop mst-launcher
STEP 7:
Preload the below library files for omxh264enc plugin.
export LD_PRELOAD=/usr/lib/libwayland-client.so.0:/usr/lib/libwayland-egl.so:/usr/lib/libopenmaxil.so
STEP 8:
Run cvr-gst-rpi binary to transmit data into AWS server.
cvr-gst-rpi
root@raspberrypi3-rdk-camera:~# cvr-gst-rpi
Conf file /etc/debug.ini open success
rdk_logger_init /etc/debug.ini Already Stack Level Logging processed... not processing again.

s for pipelin
STEP 8:
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.
Limitations
CVR Support in AWS cloud through gstreamer kvs sink.
