Validation Procedure of RMS with RTSP streaming
...

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 :
...
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:
- RMS with RTSP validation using v4l2
Disable 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
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

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:

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

pushStream uri=rtsp://192.168.43.146:5544 localStreamName=stream2
Command entered successfully!

STEP 1012:
On VLC player, for RTSP streaming
...
Note: VLC player available PC and RPI target should run in same network.
Limitations
- RMS validation with libcamera works only with SD resolution.
- Observed 2 to 3 sec's of glitches in RMS with RTSP validation using both v4l2 and libcamera
