If you plan to use a secure video chat app to communicate with your audience, you should consider implementing a video API and SDK. In this blog, we will go through all the vital aspects of selecting the best live video call SDK to help you build a robust communication system. Before we get deeper into the specifics, let’s get our basics about Live video call API.

Why Do We Need Live Video Call SDK?

An SDK (Software Development Kit) is a set of tools that greatly simplifies the app development process. The SDK includes a library of features, functionalities (code pieces), and visual editors for developing video calling applications for any platform. However, there are many reasons to choose Live Video Call SDK. Some of the few reasons for using live video SDK to build the live video call feature are as follows:

  • Human Capital Requires No Investment

To develop live video technology, you must assemble at least a 6-member team. Maintaining and growing the team is a long-term project. The return on investment for the team will be incredible.

  • Backend Infrastructure Requires No Investment

To speed up data transmission and ensure the quality of live video calls, you must build a data transmission network to transmit multimedia data. The data network consists of a large number of data centres and dedicated leased lines.

  • System Maintenance Requires No Investment

System maintenance is an ongoing task that needs continuous investment in a maintenance team. System failures are unavoidable.

  • Fast Time to Market

In market competition, speed is critical. When you notice a trend or have an idea, it is critical to put it into action and test it as soon as possible. If you wait too long, your fortune will be lost.

Industrial Applications of Live Video Call SDK

Live video SDK has many applications. It will fit into one of the categories according to your intended use.

  • Online Social and Entertainment

A live video call in a live video streaming scenario enables the host to interact with audience members or guests. Interactive live video streaming enables hosts to create a more sticky and interactive environment while driving revenue growth.

  • Online Education

Small and medium-sized classes need interaction between teachers and students. On the video, the entire class will be able to see the teacher and the speaking student’s conversations.

  • Video Customer Services

Live video calls can help improve the effectiveness and efficiency of online customer service.

  • Telehealth

Generally, telehealth requires a one-on-one live video call. In the live video call for diagnosis, the doctor and patient can communicate clearly.

  • Live Online Events

Generally, events are held offline for the purposes of advertising and branding. However, in the event of a prolonged pandemic, it has become popular to host live events online via live streaming.

What Are the Basic Features of Live Video Call SDK?

The following are some of the basic features of Live Video Call SDK:

  • Video Stream Mixing

It allows you to merge two or more video streams into one (voice stream is included by default). Stream mixing is commonly used in broadcasting situations, such as live video streaming to a large audience.

  • Streaming Media Files

Generally, Live video call SDK providers will provide you with a much more powerful media player than a standard media player. Furthermore, if you load a background music file into the media player during a live video call, it will mix the music audio stream with the vocal audio stream captured from the microphone, and then publish the mixed stream to the real-time data network.

  • Streaming From a Network URL

The media player can also play voice/video streams with network URLs. It functions similarly to playing streams loaded from local files. If the network resource is a video, the media player can play and render it.

  • Screen Sharing

It is a standard feature of secure video calls and online classrooms. The screen-sharing feature captures screen images and generates a stream that is played at the receiver end. 

  • Local Media Capture

The feature lets you capture streams and save them as media files locally. You can start previewing and recording the video source as a media file without publishing the video as a stream.

What Are the Advanced Features of Live Video Call SDK?

  • Video Watermark

Video watermarks can help you demonstrate your brand while making it difficult to steal or edit the video’s content.

  • Video Screenshot

It gives you the ability to create video snapshots of ongoing video calls. It allows you to select the level of definition for the snapshot images.

  • CDN Distribution

CDN is a cost-effective way to support high concurrency. The feature allows you to publish a stream directly to a CDN or forward a stream from the real-time data network to a CDN.

  • H.265 Encoding and Decoding

With H.265, the live video call SDK can significantly reduce bandwidth costs while maintaining the same level of video quality.

  • Customized Video Processing

Customized video processing can be divided into three categories: customized video capturing, customized video pre-processing, and customized video rendering. Customized video capturing means that the live video call SDK does not capture video from the physical camera, but instead it receives video data from another source, which is then processed for the intended purpose. Customized video pre-processing entails obtaining raw video data from the SDK, processing it, and returning it to the SDK.

How to Pick the Best Video Call SDK?

When selecting a Live Video Call SDK, consider the following factors:

  • Easy-to-Integrate

It is critical to ensure that the live video call SDK is easy to integrate.

  • Multi-platform and Language Support

Ensure that the Video Call SDK supports multiple platforms and languages to facilitate video call integration.

  • Strong security

The live video calling SDK you choose must be able to safeguard all in-app chats and files from third-party intrusions with protocols like E2E, AES, and TLS/SSL. Furthermore, video calling SDKs must comply with industry-regulatory standards like HIPAA and GDPR.
