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-3 device. This page dedicated to bringing up and validation of RMS functionality in RPI-3.
Yocto Build Steps
Refer below link to build camera image
RDK-C Build Instruction for RPI-3
Image Flash Procedure
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
network={
ssid="username"
psk="password"
}
Console output
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
update_config=1
network={
ssid="XXXX"
psk="YYYYYYYYY"
}
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
Console output
RRSIP=XXX.XXX.XXX.XXX 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
Console output
root@raspberrypi0-rdk-camera:~# ifconfig

STEP 5:
check loaded module by using below command
lsmod
Console output

STEP 6:
check camera device there or not by using below command
ls /dev/video0
Console output
root@raspberrypi0-rdk-camera:~# ls /dev/video0 /dev/video0
