Identify and Resolve Video Call Lag Issues

In today’s fast-paced digital world, video calls have become an essential communication tool for communication. It is popular whether for personal connections or professional collaborations. However, video call lag can significantly impact the user experience, leading to frustration and miscommunication. In this blog post, we will explore the main causes of video call lag. Also the blog provides actionable steps to identify and resolve these issues using ZEGOCLOUD’s advanced Video Call solutions.

What Are the Common Causes of Video Call Lag?

The common causes of video call lag includes network instability, device performance, and software and application issues.

Network Instability

One of the most common causes of video call lag is network instability. This can occur due to various factors, such as weak internet connections, high latency, or packet loss. When the network is unstable, the video and audio data packets may not be transmitted smoothly. It may result in lag or stuttering.

Weak Internet Connection: A weak or fluctuating internet connection can cause the video and audio to buffer or freeze.
High Latency: High latency, or the delay in data transmission, can result in a noticeable lag between the speaker’s actions and the viewer’s perception.
Packet Loss: When data packets are lost during transmission, it can lead to gaps in the video and audio stream, causing stuttering or freezing.

Device Performance

The performance of the used devices for the video call can also impact the quality of the call. Devices with limited processing power may struggle to handle the demands of high-quality video and audio encoding and decoding.

CPU and Memory Constraints: If the device’s CPU or memory is overloaded, it can lead to performance issues during the video call.
Outdated Software: Running outdated operating systems or applications can also cause performance problems, as developers often release updates to improve performance and fix bugs.

Software and Application Issues

The video call application itself can also be a source of lag. Bugs, glitches, or compatibility issues within the application can cause it to perform poorly.

Application Bugs: Like any software, video call applications can have bugs that affect performance. Developers regularly release updates to address these issues.
Compatibility Issues: Compatibility issues between the video call application and the device’s operating system or hardware can also cause performance problems.

How to Identify and Resolve Video Call Lag Issues with ZEGOCLOUD’s Video Call Solution

Check Your Network Connection

The first step in troubleshooting video call lag is to check your network connection. ZEGOCLOUD Video Call aims to optimize network performance, but it’s still important to ensure that your internet connection is stable and reliable.

Test Internet Speed in Advance: ZEGOCLOUD offers a network speed testing feature. Before initiating a call or accepting a call, users can start a speed test by calling the startNetworkSpeedTest method (Read ZEGOCLOUD Doc Test network and devices in advance for more information). It allows users to detect upstream and downstream network speeds. The speed data helps determine the optimal audio/video stream bitrate suitable for publishing/playing under current network conditions. When upstream speed test results indicate a high packet loss rate, it is recommended to reduce the streaming bitrate by lowering resolution or frame rate to ensure stable publishing. When downstream speed test results show high packet loss, it is advised to utilize the layered video encoding feature provided by the SDK to play lower-bitrate streams, thereby ensuring reliable stream pulling (Read ZEGOCLOUD Doc Configure video codec method for more information).
Monitor Stream Quality While Calling: ZEGOCLOUD provides the ability to monitor the streaming quality, user status, video resolution, and upstreaming/downstreaming network speed. After a video calling started, users can obtain real-time streaming data by listening to the callbacks of onPublisherQualityUpdate and onPlayerQualityUpdate (Read ZEGOCLOUD Doc Monitor streaming quality for more information).
When a call has begun, the users can listen to the callback
Reduce Bandwidth Usage: Before a user starts a call, they can call the enableTrafficControl method (Read ZEGOCLOUD Doc Configure bandwidth management for more information). After that, the SDK will dynamically adjust the bitrate, frame rate, resolution, and audio bitrate of video streaming based on the local and remote network conditions. It automatically adapts to the current network environment and fluctuations to ensure smooth audio and video streaming. This can help free up resources for your video call.

Optimize Your Device Performance

If your network connection is stable, the next step is to optimize your device’s performance. ZEGOCLOUD’s’s solutions are designed to work efficiently on a wide range of devices, but it’s still important to ensure that your device is running smoothly.

Close Background Applications: Close any unnecessary applications running in the background to free up CPU and memory resources.
Update Your Software: Ensure that your operating system and video call application are up to date with the latest versions.
Restart Your Device: Restarting your device can help clear any temporary glitches and improve performance.

Address Software and Application Issues

If the issue persists, it may be related to the video call application itself. ZEGOCLOOUD’s platform includes advanced tools for monitoring and optimizing video call quality, helping you identify and resolve issues in real-time.

Update the Application: Check for updates to the video call application and install them if available.
Reinstall the Application: If updating the application does not resolve the issue, try uninstalling and reinstalling the application.
Check for Compatibility Issues: Ensure that your device meets the system requirements for the video call application. If you are using an older device, consider upgrading to a newer model.
