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.

RDK-C rdk-next Yocto 3.1 dunfell build for Raspberrypi
STEP 1:
Add require SSID and PSK in /etc/wpa_supplicant.conf file in below format
network={
ssid="username"
psk="password"
}
Code Block | ||||
---|---|---|---|---|
| ||||
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
update_config=1
network={
ssid="XXXX"
psk="YYYYYYYYY"
}
|
STEP 2:
Add below configuration in end of the /boot/config.txt file
dtoverlay=imx219
core_freq_min=250
Code Block | ||||
---|---|---|---|---|
| ||||
vi /boot/config.txt
dtoverlay=imx219
core_freq_min=250 |
STEP 3:
Disable dtoverlay and minimum freq configuration in config.txt file
Code Block | ||||
---|---|---|---|---|
| ||||
vi /boot/config.txt
#dtoverlay=imx219
#core_freq_min=250 |
Run mediastreamer binary with v4l2src configuration.
Code Block | ||||
---|---|---|---|---|
| ||||
vi /lib/rdk/startMST.sh
#Run mediastreamer binary in background
# 1. To validate streaming with v4l2 need to give "mediastreamer v4l2src &"
# 2. To validate streaming with libcamera need to give "mediastreamer libcamerasrc &"
# If we change 1 and 2, need to reboot the target and validate streaming.
mediastreamer v4l2src & |
2. RMS with RTSP validation using libcamera
Enable dtoverlay and minimum freq configuration in config.txt file
Code Block | ||||
---|---|---|---|---|
| ||||
vi /boot/config.txt
dtoverlay=imx219
core_freq_min=250 |
Run mediastreamer binary with libcamerasrc configuration.
Code Block | ||||
---|---|---|---|---|
| ||||
vi /lib/rdk/startMST.sh
#Run mediastreamer binary in background
# 1. To validate streaming with v4l2 need to give "mediastreamer v4l2src &"
# 2. To validate streaming with libcamera need to give "mediastreamer libcamerasrc &"
# If we change 1 and 2, need to reboot the target and validate streaming.
mediastreamer libcamerasrc & |
STEP 4:
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 5:
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 | ||||
---|---|---|---|---|
| ||||
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 6:
WiFi connection is must needed for RMS validation.
Check WiFi connection by using below command.
ifconfig
Code Block | ||||
---|---|---|---|---|
| ||||
root@raspberrypi3-rdk-camera:~# ifconfig

STEP 7:
check loaded module by using below command
lsmod
Code Block | ||||
---|---|---|---|---|

STEP 8:
check camera device there or not by using below command
ls /dev/video0
Code Block | ||||
---|---|---|---|---|
| ||||
root@raspberrypi0-rdk-camera:~# ls /dev/video0
/dev/video0 |
STEP 9:
Need to stop below service file to validate gstreamer based live streaming
systemctl stop rms-launcher.service
systemctl stop pipewire-launcher.service
systemctl stop mst-launcher.service
Need to do below changes in config.lua file
vi /usr/local/rms/config/config.lua
Code Block | ||||
---|---|---|---|---|
| ||||
-
+ ]]--
-- RTSP
{
- ip="127.0.0.1",
+ ip="0.0.0.0",
port=5544,
protocol="inboundRtsp",
},
-
+ --[[ |
After stoping those service file, then we need to start/trigger below service and binaries.
Code Block | ||||
---|---|---|---|---|
| ||||
root@raspberrypi3-rdk-camera:~# systemctl start mst-launcher |
To start RMS binary , We need to go cd /usr/local/rms/bin directory
Code Block | ||||
---|---|---|---|---|
| ||||
root@raspberrypi3-rdk-camera:~# cd /usr/local/rms/bin/
root@raspberrypi3-rdk-camera:/usr/local/rms/bin# ./rdkcmediaserver ../config/config.lua & |
Need to check mediastreamer and RMS running status with below command
Code Block | ||||
---|---|---|---|---|
| ||||
root@raspberrypi3-rdk-camera:~# ps -Af | grep media
root 2396 1 1 15:30 ? 00:00:00 mediastreamer v4l2src
root 2555 1613 30 15:31 pts/0 00:00:01 ./rdkcmediaserver ../config/config.lua
root 2574 1613 0 15:31 pts/0 00:00:00 grep media |
STEP 10:
Enter into the Telnet console with telnet command
telnet localhost 1222
Code Block | ||||
---|---|---|---|---|
| ||||
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.
Code Block | ||||
---|---|---|---|---|
| ||||
listconfig
Command entered successfully!
Run-time configuration

roomid: rpi0
rrsip: 18.224.54.11
rrsport: 81 |
If the webrtc detail is available in listconfig, we need to stop webrtc with "stopwebrtc" command
Code Block | ||||
---|---|---|---|---|
| ||||
stopwebrtc
Command entered successfully!
Stopped WebRTC Negotiation Service |
After did the stopwebrtc, check the listconfig
Code Block | ||||
---|---|---|---|---|
| ||||
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
Code Block | ||||
---|---|---|---|---|
| ||||
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
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.
