Introduction

WebRTC (Web Real-Time Communication) is a technology that enables Web applications and sites to capture and optionally stream audio and/or video media, as well as to exchange arbitrary data between browsers without requiring an intermediary. The set of standards that comprise WebRTC makes it possible to share data and perform teleconferencing peer-to-peer, without requiring that the user install plug-ins or any other third-party software.

openwebrtc Compilation Procedure For X86

STEP 1:

Below command is cloning the openwebrtc opensource openwebrtc  source into current PC.

git clone https://github.com/rdkcteam/openwebrtcnative-m72webrtc.git

STEP 2:

Goto native-webrtc/PC_Streamer folder and give below export commands.

sudo chmod 777 webrtc_browser.sh 

./webrtc_browser.sh 

STEP 2:

Goto openwebrtc-m72 folder and give below export command.

export PATH=$PATH:/home/user/Desktop/openwebrtc-m72/buildtools/linux64/

STEP 3:

Completion of step2  the binaries are generated into native-webrtc/PC_Streamer/webrtc-checkout/out/Default folder inside.

Validation Procedure of Webrtc

Follwing steps are run into Desktop PC(X86) Side:

STEP 1 , STEP 2, STEP 3, STEP 5 , STEP 6, STEP 7.

Follwing step are run into RPI Board Side:

STEP 4

STEP 1:

Run the peerconnection_server binary located at (native-webrtc/PC_Streamer/webrtc-checkout).

./peerconnection_server

STEP 2:

Open new terminal Goto openwebrtc-m72/out/Defaultpathand path, run the below two commands one by one.

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$(pwd)

./peerconnection_client

Refer the below peerconnection_client GTK window.

STEP 3:

Provide IP address of server pc and press connect button.

Refer the below peerconnection_client GTK window.

STEP 4:

Stop below service before runing the peerconnection_client binary.

systemctl stop rms-launcher
systemctl stop mst-launcher

Run the peerconnection_client binary into RPI board side and Enter server PC IP address, port numner.

peerconnection_client

STEP 5:

Need to Check whether the peerconnection_server side both clients are connected are not.

STEP 6:

PC side peerconnection_client GTK window shows the number of peers client devices areconnected list.
