RDK-C : Video Playback With WebRtc(Web Real-Time Communication)

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  source into current PC.

git clone https://github.com/rdkcteam/openwebrtc-m72.git

STEP 2:

Goto openwebrtc-m72 folder and give below export command.

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

STEP 3:

Run the below command.

gn gen out/Default --args='rtc_use_h264=true is_component_ffmpeg=true rtc_libvpx_build_vp9=false rtc_use_gtk=false rtc_include_tests=false'

STEP 4:

Run the below command.

ninja -C out/Default

Completion of above command all the binaries are generated into 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 (openwebrtc-m72/out/Default).

./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 are connected list.

STEP 7:

Double click user@rasspberrypi3-rdk-camera from the listed peer connected devices.
