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-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. 

Build and Flash Procedure

Refer below link to build camera image

RDK-C Build Instruction for RPI-0

RDK-C Build Instruction for RPI-3


Dunfell:

RDK-C rdk-next Yocto 3.1 dunfell build for Raspberrypi

Validation Procedure of RMS with RTSP streaming

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:

WiFi connection is must needed for RMS validation.

Check WiFi connection by using below command.

ifconfig

Console output
root@raspberrypi3-rdk-camera:~# ifconfig

STEP 4:

check loaded module by using below command

lsmod

Console output
root@raspberrypi3-rdk-camera:~# lsmod

STEP 5:

check camera device there or not by using below command

ls /dev/video0

Console output
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 &

Console output
root@raspberrypi3-rdk-camera:~# pipewire &


STEP 8:

Run the pipewire media session binary with below command

pipewire-media-session &

Console output
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 &

Console output
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

Console output
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.

Console output
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: 
      -- 
        configId: 2
        roomid: rpi0
        rrsip: 18.224.54.11
        rrsport: 81


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

Console output
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.
