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.

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:
Add below configuration in end of the /boot/config.txt file
dtoverlay=imx219
core_freq_min=250
Code Block | ||||
---|---|---|---|---|

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 :
...
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
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 4:
WiFi connection is must needed for RMS validation.
Check WiFi connection by using below command.
ifconfig
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

---|---|---|---|---|
| ||||
RRSIP=XXX.XXX.XXX.XXX
RRSPORT=81
ROOMID=rpi0

After resolution modification need to reboot the target.
Note: This step is not necessary,it is depends on your resolution validation.
STEP 6:

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 directoryls /dev/video0
Code Block | ||||
---|---|---|---|---|
| ||||
root@raspberrypi0root@raspberrypi3-rdk-camera:~# lscd /dev/video0 /dev/video0 |
STEP 7:
Check mediastreamer and rms binaries are running or not before RTSP streaming validation.
/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 commandps -Af | grep media
Code Block | ||||
---|---|---|---|---|
| ||||
root@raspberrypi3-rdk-camera:~# ps -Af | grep media root 2396 197 1 1 13 1015:5730 ? 00:0400:4000 mediastreamer v4l2src root 10072555 1613 1 3 10:57 ? 30 15:31 pts/0 00:00:01:05 ./rdkcmediaserver ../config/config.lua root 109592574 19431613 0 1115:3231 ttyS0pts/0 00:00:00 grep media |
STEP 810:
Enter into the Telnet console with telnet command
...
Code Block | ||||
---|---|---|---|---|

listconfig Command entered successfully! Run-time configuration dash: [] hds: [] hls: [] metalistener: [] mss: [] process: [] pull: -- configId: 1 localStreamName: stream2 status: current: description: Streaming uniqueStreamId: 1 uri: sercom://0 push: [] record: [] webrtc: [] |
STEP 911:
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 | ||||
---|---|---|---|---|

STEP 1012:
On VLC player, for RTSP streaming
...
Note: VLC player available PC and RPI target should run in same network.
