The on-going COVID-19 situation has changed people’s lives impacting the world’s economical status resulting in work from home situations with social distancing. Eventually, this has made the leading companies to think of other possibilities to stay connected with their employees and clients, leading them to video calling technology.
According to Valuates report, video conferencing has an estimated worth of $4.56 billion in 2020, which is expected to hit $7.73 billion by the end of 2027. However, this has turned around everyone’s eyes starting from developers to small businesses to invest in this incredible delight.
Thus, I recommend you to have a look at this post before planning to build your video conferencing app where you just need to integrate the video conferencing APIs and SDKs into your third party devices like iOS, Android and web app instead of building something from scratch.
So, with no more delay let’s start over.
Everything You Need to Know About Video Conferencing API & SDK
Before getting into an in-depth study about building a real-time video conferencing app, it is necessary to have some understanding about the basic requirements – APIs and SDKs,
What is an API?
API refers to Application programming Interface which acts as an intermediary tool that enables two applications to communicate with each other. Implementation of these APIs simplifies the applications development by saving money and time. APIs provide flexibility and simplify the design for an innovative approach to technology.
What is SDK?
SDK refers to a software development kit that allows the software developers to create an application for a specific platform or programming language. Moreover, we can define it as a toolkit that has a collection of APIs as a package that can be assembled easily to develop an app. However, this kit varies from industry to industry depending upon their specific requirement.
Some of the video calling API and SDK includes,
- Screen Sharing
- Voice Features
- Video/Voice Calling and Recording
- Variety of Conferencing Formats
Now, let’s have a check on some of the benefits of online video conferencing apps.
7 Ways the Business Benefited from Video Conferencing SDKs & APIs!
Even when there is an issue with pandemic, the video conferencing technology has never been set apart from presenting countless opportunities to businesses.
It’s engaging contribution has always connected the people and businesses or can say they have literally transformed and tuned the digital platform with so many benefits. Let’s have a talk on some,
1. Quick Reach at Your Comfort
No worries to travel to see your clients and colleagues, it’s the video conferencing APIs that has made a way to quick connection with face-to-face interaction denying the time-zone and geographical location. Here, users can seamlessly communicate with anybody around the clock from the comfort of their home.
2. Save Time and Money
Video conferencing SDKs not only comfort the connection with virtual interaction, but it also saves traveling time and the related expenses. However, sometimes some of the meetings do demand a direct presence, but most of them reach the resolution via video conferencing app.
3. Online Meeting at More Personalized Manner
When compared to email or audio calls, video conferencing apps take every interaction to the utmost next level wherein you can have face-to-face interaction with other users and have more personal relationships.
4. Recording Option
It’s always worth having a track of all the meetings via a recording option. This ensures the host not to miss even a single point that has been discussed in the meeting. Sometimes, these recordings will be valuable for those who were unavailable during the meeting.
5. Training the Employees
Most of the time HR departments often use these video conferencing technologies for onboarding and offboarding purposes. This is proven to be the most possible cost effective way to educate and train their remote employees about their company’s protocols, products and service, etc.
6. Easy Accessibility
Getting equal opportunity to engage and participate is really a challenging task. But with live video conferencing, it has become easier for the participants to present their views by notifying the host by clicking on the video options.
7. Supports in Business Decisions
Maintaining better human connection is now too easy with secure video conferencing. Most of the time, this helps and speeds up the decision making process by engaging with global clients at once.
That’s been said, these video conferencing apps are needed by almost all the industries. But still there are certain industries that need them the most for a variety of reasons.
Why Do Businesses Demand Video Conferencing Apps?
Although, the need of video conferencing technology is somewhat necessary in businesses but still there are many businesses that needs them the most for a variety of reasons that includes,
- High-End Security
The video conferencing APIs and SDKs are built-in with security standards that makes it the most desirable one for all industries. These include GDPR, HIPAA Compliance, End-to-end Encryption, etc.
- Additional Capabilities
Most of the real-time communication providers offer their APIs and SDKs with custom options depending upon respective industrial needs. Therefore, they come with AI/ML capabilities that allow them to generate analytics for video calling.
Building an app is not as easy as it seems to be, it will consume a lot of time and money but, using APIs you can develop and unleash the power of real time communication apps easily. Since these APIs are highly flexible, they can be added into any third party application like iOS, Android and web apps within a considerable time frame.
Key Challenges While Building a Video Conferencing App from Scratch!
When you are planning to build a real-time communication app, there are some unavoidable challenges that must be looked into. This includes,
- Extra Delivery Time
When you are building a video conferencing app from scratch, you can not specify the time duration as it may vary depending upon the resources, infrastructure, etc. Even sometimes if you have a team, the development process moves across several iterations before finalizing. Moreover, the software testing requires it to be coded from the ground level.
- Complexities with Operations Management
When you are building a solution from scratch, there are possibilities for certain complexities with operational management. Here, you will have to deploy and manage the entire infrastructure until the app reaches the market.
- Security Issues
While developing an application from scratch, the security requirement is one of the major issues to be pointed out. It is necessary to see the app meets all the necessary regulations and compliances.
However, there are several challenges but the above are the major issues that must be considered while developing a video conferencing app from scratch. Henceforth, it is always better to go for APIs or SDKs to develop an application.
Now, let’s see how these video calling APIs and SDKs interact with any existing app in terms of technical aspects.
How Video Conferencing SDKs Communicate with Your App?
There are three ways for a video conferencing app to incorporate with your existing app,
1. Credentials for Video Conferencing SDK Account
Before integrating the SDKs and its related services into your client’s app, it is necessary to acquire credentials.
2. Server-Side Application
Since the APIs run at your application server, it uses the third-party account credentials to provide access to any video services.
3. Client-Side Application
All the client apps are executed at a variety of devices like mobile or web apps. So, these APIs use third-party SDKs to publish, subscribe, and execute the real-time communication information.
To initiate a video conferencing session there are a certain set of steps that need to be followed. Let’s have a look at,
1. Create a Room
First, the server application will ask video conferencing SDKs permission to create a meeting room. Now, the SDKs will validate the provided information before creating a new room. Once the validation is done, these video SDKs will respond with the Room SID, a unique identifier that can be used in API requests.
2. Obtaining Access Token for Client 1
Clients need to access a token for connecting to a meeting room ensuring that the client application has full control as to who is authorized to join the meeting room.
- Usually the access token is requested from the application server through HTTP request from the client app
- The application server make use of video SDK account credentials to generate an access token securely
- Now, the client 1 obtains the access token.
3. Client 1 gets into the Meeting Room
- After getting the access token the client 1 can connect to the room using video SDK’s connecting interface
- Video SDK verifies the access token. If it gets validated, the connection between the room and the client gets improved and established. Now, the client becomes a participant in the room who can be able to publish and/or subscribe to the content from other resources.
However, the above sections would have given you an idea as to which one is the best option to go for when you are planning to build your video conferencing app. Now it’s time for you to think over which one is the better approach.
Anyhow, if you are planning to integrate video conferencing APIs and SDKs to build your application, then i must say there are a lot more in the ocean to check out for.
