In the world of live streaming, providing a smooth and seamless viewing experience is crucial for engaging your audience. One common issue that streamers face is frame rate drops, which can significantly impact the quality of the stream. This problem often occurs due to insufficient device performance. In this guide, we will explore how to avoid frame rate drops during live streaming using ZEGOCLOUD‘s live streaming solutions.
Importance of Frame Rate Drop Prevention
Frame rate, measured in frames per second (fps), indicates how many individual frames are displayed per second in a video. A higher frame rate results in smoother motion and a more fluid viewing experience. In live streaming, maintaining a consistent frame rate is crucial to prevent choppy or stuttering video, which can negatively impact viewer engagement.
Why Frame Rate Drops?
Before diving into the solutions, it’s important to understand what causes frame rate drops. Frame rate drops happen when the device the user is using to stream cannot keep up with the demands of the streaming process. This can be due to a variety of factors, including:
- Insufficient CPU/GPU Performance: The central processing unit (CPU) and graphics processing unit (GPU) are responsible for encoding and rendering the video stream. If they are not powerful enough, they may struggle to maintain a consistent frame rate.
- Memory Constraints: Insufficient RAM can lead to frame rate drops as the device struggles to handle the data required for streaming.
- Overheating: Prolonged streaming can cause devices to overheat, leading to thermal throttling and reduced performance.
- Network Issues: Unstable or slow internet connections can also contribute to frame rate drops.
How to Avoid Frame Rate Drops For Your Live Streaming Users?
Live streaming quality heavily depends on device performance. When your device struggles to handle encoding, rendering, or network transmission, frame rate drops can occur, leading to a choppy viewer experience. For developers using ZEGOCLOUD Live Streaming SDK, optimizing device performance is critical. Below is a comprehensive guide to mitigate frame rate instability caused by hardware limitations.
Optimize Device Configuration
Device performance bottlenecks often stem from high CPU/GPU usage, insufficient memory, or inefficient encoding settings. Here’s how to address these issues:
- Adjust Resolution and Frame Rate
Lowering resolution (e.g., from 4K to 1080p) and frame rate (e.g., from 60 fps to 30 fps) significantly reduces computational load. ZEGOCLOUD’s SDK allows dynamic adjustments via APIs likesetVideoConfig, enabling real-time optimization based on device capabilities. - Enable Hardware-Accelerated Encoding
Leverage hardware encoders (e.g., H.264/H.265) instead of software encoding. ZEGOCLOUD’s SDK supports hardware acceleration, which offloads processing from the CPU to dedicated GPU units, improving efficiency. Read ZEGOCLOUD tech docs Output the video in H.265 for more.
Leverage Adaptive Bitrate and Encoding
Adaptive bitrate streaming ensures smooth playback by dynamically adjusting video quality based on network and device conditions.
- Use ZEGOCLOUD’s Smart QoS
ZEGOCLOUD’s proprietary QoS algorithms balance bitrate, resolution, and frame rate in real time. For example, in weak network conditions, the SDK automatically lowers bitrate to maintain frame stability without sacrificing clarity. - Multi-Streaming with SVC
SVC (Scalable video coding) is a technique to encode a video sequence into a bitstream that contains multiple sub-bitstreams (called layers)—a base layer and one or more enhancement layers. The base layer provides the basic quality of the video content, and each enhancement layer improves the video quality of its lower layers in a certain dimension: frame rate, resolution, or bitrate. As a result, the stream subscriber can choose to receive and decode only the base layer or the base layer plus a certain number of enhancement layers according to its available bandwidth and terminal characteristics (for example, screen size).

Monitor and Troubleshoot Performance
Proactive monitoring helps identify bottlenecks before they impact viewers.
- Utilize ZEGOCLOUD Analytics Dashboard
ZEGOCLOUD’s Analytics Dashboard provides real-time metrics like transmission bitrate, frame rate, packet loss rate, and latency. Use it to pinpoint performance issues and adjust settings accordingly. - Analyze Logs for Resource Contention
High CPU/GPU usage often correlates with background apps or inefficient code. ZEGOCLOUD’s SDK logs detail resource utilization, helping developers optimize processes like video capture or encoding threads.
Optimize Network Transmission
Even with sufficient device power, network instability can indirectly cause frame drops by forcing encoders to compensate.
- Adopt ZEGOCLOUD’s AVERTP Protocol
ZEGOCLOUD’s proprietary AVERTP protocol reduces latency and packet loss, ensuring stable transmission even under 70% packet loss. This minimizes encoder strain caused by retransmissions. - Leverage MSDN (Massive Sequential Data Network)
MSDN optimizes global routing, reducing transmission hops and improving bandwidth efficiency. This is particularly useful for devices in regions with poor connectivity.
Best Practices for Low-End Devices
- Prefer Low-Latency Live (L3) for Resource Efficiency
ZEGOCLOUD’s L3 product combines RTC and CDN benefits, offering sub-second latency while consuming fewer resources than traditional CDN solutions. This is ideal for devices with limited processing power. - Enable Multi-Threaded Encoding
Distribute encoding tasks across CPU cores. ZEGOCLOUD’s SDK supports multi-threaded processing, balancing workloads to prevent single-core overload. - Test on Target Devices
Use ZEGOCLOUD’s device compatibility list to validate performance on common low-end models.
