#Zoom Meeting SDK Linux Sample App

The is a sample app for Zoom Meeting SDK Linux. It demonstrates access to raw audio and raw video in a headless docker environment.

Prerequistes

Zoom Account
Zoom Meeting SDK App Type
Authentication token signed by
1. Client ID
2. Client Secret
Meeting Recording Token (Optional)
Docker environment
Linux or Windows with WSL environment.
VS Code or Visual Studio ======================================================================

Getting Started

Download Linux Meeting SDK from marketplace.zoom.us

1 Please decompress the downloaded zoom-meeting-sdk-linux_x86_64-5.xx.x.xxxx.tar and copy the files in the decompressed folder to these sample-app folders

h to demo/include/h
qt_libs to demo/lib/zoom_meeting_sdk/qt_libs
all the lib******.so files to demo/lib/zoom_meeting_sdk/lib******.so
copy translation.json to demo/lib/zoom_meeting_sdk/json
softlink libmeetingsdk.so to libmeetingsdk.so.1 within demo/lib/zoom_meeting_sdk/ . You can use the command ln -s libmeetingsdk.so libmeetingsdk.so.1 to do so.

2 Execute cmake -B build in demo/ folder . After successful cmake, the demo/build/ folder will be generated.

3 Execute make in the /demo/build/ directory to compile

Notes for using the demo:

The sdk auth token, password, meeting number etc.. needs to be written in the config.txt file. The recording_token when entered, will allow you to recording with additional actions from host.

GetVideoRawData, GetAudioRawData, SendVideoRawData, SendAudioRawData are boolean control variables. You can search for them in the sample code to understand the flow.

Disclaimer

Please be aware that all hard-coded variables and constants shown in the documentation and in the demo, such as Zoom Token, Zoom Access, Token, etc., are ONLY FOR DEMO AND TESTING PURPOSES. We STRONGLY DISCOURAGE the way of HARDCODING any Zoom Credentials (username, password, API Keys & secrets, SDK keys & secrets, etc.) or any Personal Identifiable Information (PII) inside your application. WE DON’T MAKE ANY COMMITMENTS ABOUT ANY LOSS CAUSED BY HARD-CODING CREDENTIALS OR SENSITIVE INFORMATION INSIDE YOUR APP WHEN DEVELOPING WITH OUR SDK.


meeting_number: "1234567890"
token: "xxxxxxxx.yyyyyyyyyyyyyyyyyy.zzzzzzzzzzzzzzzzz"
meeting_password: "123456"
recording_token: ""
GetVideoRawData: "true"
GetAudioRawData: "true"
SendVideoRawData: "false"
SendAudioRawData: "false"

You need to fill in withoutloginParam.userName = ""; in meeting_sdk_demo.cpp. meeting_sdk_demo.cpp is the starting point of the demo app.
Once init sdk and auth sdk are successfully executed, only then you can join and leave meeting.
Once you have successfully joined a meeting, subscribing to raw audio and raw video requires either
1. either host/co-host/local-recording rights or
2. meeting recording token
You will need a file named ~\.config.us\zoomus.conf before you can access raw audio in an environment without soundcard, such as docker and WSL environment. The sample zoomus.conf file is generated in the setup-pulseaudio.sh files
For Sending Raw Audio and Raw Video, there are 2 methods (turnOnSendVideoAndAudio and turnOnSendVideoAndAudio) which you will need to call

CMakeLists.txt

If you have additional cpp and/or .h files, you might need to be included in this CMakeLists.txt

add_executable(meetingSDKDemo

Docker

The sample app has been tested on Centos 8, Centos 9, Ubuntu 22 and Ubuntu 23. Here are some dependencies you will need to include.

Centos

This is tested on WSL and Docker centos 9 and Centos 8 Here are some dependencies to get it to run on Centos. Some packages might be redundant, and has not been optimized.

Install files for compiling

sudo yum install cmake
sudo yum install gcc gcc-c++

Enable the CodeReady Linux Builder repository

sudo dnf config-manager --set-enabled crb

Install the EPEL RPM.

sudo dnf install epel-release epel-next-release

CURL related dependencies

yum install -y openssl-devel
yum install -y libcurl-devel

Install Pulseaudio

yum install -y  pulseaudio pulseaudio-utils

If you encounter: Fatal error: SDL2/SDL.h: No such file or directory. This is no longer in used at code level, but leaving this here for legacy support purposes

sudo yum -y install SDL2-devel

If you encounter these error Messages

#/usr/bin/ld: warning: libxcb-image.so.0, needed by /root/release_demo/demo/libmeetingsdk.so, not found (try using -rpath or -rpath-link) #/usr/bin/ld: warning: libxcb-keysyms.so.1, needed by /root/release_demo/demo/libmeetingsdk.so, not found (try using -rpath or -rpath-link)

Dockerfiles

Dockerfile targetting different distros are provided in this sample app as well (Dockerfile-centos, Dockerfile-Ubuntu .....) Currently this is tested on

Centos 9 (functionality where custom function of fetching JWT Token from Web Service does not work, main SDK function works fully)
Centos 8
Ubuntu 22

Run these in /demo directory

Centos 8

docker build -t msdk-6.0.2-on-centos8-compact -f Dockerfile-Centos8/Dockerfile . docker run -it --rm msdk-6.0.2-on-centos8-compact

Centos 9

docker build -t msdk-6.0.2-on-centos9-compact -f Dockerfile-Centos9/Dockerfile . docker run -it --rm msdk-6.0.2-on-centos9-compact

Ubuntu 22

docker build -t msdk-6.0.2-on-ubuntu-compact -f Dockerfile-Ubuntu/Dockerfile . docker run -it --rm msdk-6.0.2-on-ubuntu-compact

docker build -t msdk-6.0.2-on-oraclelinux8-compact -f Dockerfile-ol8/Dockerfile . docker run -it --rm msdk-6.0.2-on-oraclelinux8-compact

Pulseaudio

The configuration for pulseaudio has been provided for you as shell scripts.

The setup is done via setup-pulseaudio.sh and setup-pulssaudio-centos.sh, this need to be run prior to running this project in a docker environment.

The script

starts the pulseaudio service,
creates a virtual speaker,
a virtual microphone, and
add a zoomus.conf file in the docker environment.
