Whether to use an encoder from hardware or software will probably be one of the most significant choices you ever have to make when live casting a professional event or gaming stream. Both encoding options come with their strengths and weaknesses, and which one you will need will mostly rely on your streaming purpose, budget, and individual tastes. The act of digitizing raw video and audio for streaming is known as encoding. Without an encoder, it would not be possible to stream the video data via the internet as it would be too heavy and large.
What is a Hardware Encoder?
A hardware encoder is a dedicated component that contains onboard processing capabilities that are optimized for encoding and offloading some of the workload from your computer. They are commonly used in professional broadcasting, live event production, and high-end streaming setups. If you need information about hardware encoders, learning the pros and cons will help you gain further understanding.
Advantages of Hardware Encoders:
- Stability and ReliabilityHardware encoders are not PC-dependent, which makes them less susceptible to crashing.
- Less LatencyThey also have very low latency, which is imperative in handling live real-time content like live sports and breaking news broadcasting.
- Smooth PerformanceSince they are not dependent on a PC CPU, they provide smooth and uninterrupted video processing, adding a high-quality touch to your streams.
- Better Quality OutputHardware encoders output better-quality video with more efficient compression.
Drawbacks of Hardware Encoders:
- ExpensiveHardware encoding equipment costs more, thus being out of reach for the average streamer.
- Less UpgradableHardware encoders leave less room for tweaking or frequent updates.
- More Tech InstallationThey could need a little more to set up and integrate with your existing streaming equipment.
What is a Software Encoder?
A software encoder is a piece of code running on a computer or server to compress and encode video to be live-streamed. These encoders are highly flexible and may be updated regularly with new additions and enhancements.
Advantages of Software Encoders:
- Budget-FriendlyMost software encoders are free or very low in price and, hence, the perfect option for novices and small firms.
- Highly FlexibleFilter deployability, customizable settings, and compatibility with other streaming software.
- Ongoing UpdatesThese are in the guise of new features and software encoder bug fixes.
- User-FriendlySoftware encoders have minimal interfaces to facilitate easy setup for streaming.
Disadvantages of Software Encoders:
- More CPU UtilizationBased on the processing power of the computer, software encoders restrict system performance.
- Latency Potential IssueSoftware encoders will introduce additional latency, which is not desirable for time-sensitive broadcasts.
- Less ReliableA system update or software crash can interrupt a live stream.
Selecting the Right Encoder for Your Application
The choice between a hardware encoder and a software encoder depends on factors such as
- CostIf cost is a significant factor, a software encoder is a cost-effective option.
- Stream Quality and StabilityTo achieve the best quality with low chances of failure, use a hardware encoder.
- Latency RequirementsThe hardware encoder makes it easier to support low-latency streaming.
- Ease of UseSoftware encoders are simpler and more convenient for new streamers to use.
Both hardware and software encoders do their job for live streaming, and, based on your needs and constraints, whichever is better out of them is yours. Professional casters and veteran streamers use the reliability and performance of hardware encoders, whereas new streamers and budget streamers use software encoders.
