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 this RTSP streaming we can able to play live streaming content in VLC player. This page dedicated to bringing up and validation of RMS functionality with RTSP streaming in RPI-0/RPI-3.

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:
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 RMS validation.
Check WiFi connection by using below command.
ifconfig
root@raspberrypi3-rdk-camera:~# ifconfig

STEP 4:
check loaded module by using below command
lsmod
root@raspberrypi3-rdk-camera:~# lsmod

STEP 5:
check camera device there or not by using below command
ls /dev/video0
root@raspberrypi0-rdk-camera:~# ls /dev/video0
/dev/video0
STEP 6:
Before validate this use case we should stop rms binary and mediastreamer binary with below command.
systemctl stop rms-launcher
systemctl stop mst-launcher
STEP 7:
Run the pipewire binary with below command
pipewire &
root@raspberrypi3-rdk-camera:~# pipewire &
STEP 8:
Run the pipewire media session binary with below command
pipewire-media-session &
root@raspberrypi3-rdk-camera:~# pipewire-media-session &
STEP 9:
Run the RMS binary with below command
cd /usr/local/rms/bin/
./rdkcmediaserver ../config/config.lua &
root@raspberrypi3-rdk-camera:~# cd /usr/local/rms/bin/
root@raspberrypi3-rdk-camera:/usr/local/rms/bin# ./rdkcmediaserver ../config/config.lua &
[3] 21317
root@raspberrypi3-rdk-camera:/usr/local/rms/bin#
Successfully retrieved the MAC as b8:27:eb:87:67:91
got video format: H264
size: 1280x720
framerate: 25/1
STEP 10:
Enter into the Telnet console with telnet command
telnet localhost 1222
root@raspberrypi3-rdk-camera:~# telnet localhost 1222
Trying ::1...
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
After entering the telnet console need to stop webrtc streaming, so we should check webrtc status with "listconfig" command.
listconfig
Command entered successfully!

STEP 11:
At that same telnet console,need to give the below command for RTSP streaming
pushStream uri=rtsp://camera_ip:5544 localStreamName=stream2
Example:
pushStream uri=rtsp://192.168.43.146:5544 localStreamName=stream2
pushStream uri=rtsp://192.168.43.146:5544 localStreamName=stream2
Command entered successfully!
Local stream stream2 enqueued for pushing to rtsp://192.168.43.146:5544 as stream2
configId: 4
forceTcp: false
keepAlive: true
localStreamName: stream2
targetStreamName: stream2
targetStreamType: live
targetUri:
fullUri: rtsp://192.168.43.146:5544
port: 5544
scheme: rtsp
STEP 12:
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.
