What Is In-App Live Streaming?

In-app live streaming is a technology that lets users broadcast and watch live video in mobile apps. With this technology, people can create and view live content without switching to other apps or websites. This is the thing that sets it apart from traditional platforms that need separate apps or web pages. 

In-app streaming provides a smooth experience for content makers and viewers. Mobile tech has grown and the Internet has gotten faster. People now want content instantly more than before. 

This technology works in different types of apps. You’ll spot it in social media, games, learning, and even health apps. It’s almost everywhere – for showing off products, streaming events live, answering questions, and teaching skills. 

Key Benefits Of In-App Live Streaming

Before we get any further, let’s look at some of the major advantages of using live streaming in apps. There are several reasons why you’ll need live streaming for your business. We’ve curated a list you must know. 

1. It’s Super-engaging  

Live video streams really get people so excited. It is more fun to watch something that is broadcasted live than the pre-recorded content, right? That’s because you get to see people in real-time, and actually feel whatever they do on live is authentic and not scripted. It basically connects with the viewers that any recorded content. 

Have you felt this – when you’re watching live, you feel like you’re actually there with the streamer. This is also a reason why people love to hop in live streams just to look at what the person they follow is up to, for real.  

From a business perspective, this drives a lot of viewers and keeps them on the app for a long time. 

2. Real-Time Interaction 

Comments on pre-recorded content are great. But, what’s real fun is the opportunity to interact with the favorite influencer/ star on live. You simply can ask them stuff, and they can answer really quick. While it matters to the streamer to keep things real and responsive to retain viewer trust, the audience feel more personally connected, wanting to hang on the content. 

3. Authenticity 

When you’re watching live, you’re seeing things as they happen. No one’s setting it up or following a script. You just get to see the real person talking, or what’s really going on behind the scenes at a company.

This realness is what makes people trust your product/ service more. It doesn’t matter if it’s a boss who’s talking to customers or just some influencer showing what they’re up to. Simply put, it makes the person or company seem more down-to-earth and easier to relate to.

4. Independent Broadcasting 

In-app live streaming lets users become broadcasters themselves. It’s like putting the power to create content in everyone’s hands. Anyone with a good idea can share it with the world. 

Got a smartphone? You can start your own live stream. You can share experiences, thoughts, or talents with others. 

For businesses, this means they can encourage user-generated content. For people using these apps, it’s like getting a stage to be yourself. You can show off who you really are and what you’re into. 

Plus, it’s a great way to find your tribe – you know, other people who like the same stuff you do.

5. Monetization Opportunities 

Live streaming in apps can help people earn money. If you are a streamer, you can make money out of ads, sponsorships, or fans who want to contribute. Some apps let viewers buy gifts or tokens to support streamers they like. 

For businesses, this is another easiest way to promote their products to millions of viewers. This will eventually increase sales, convert leads and attract more revenue.

Key Technical Aspects of In-App Live Streaming

In-app live streaming can sound fun and engaging. But there are loads of technical aspects that are involved behind the working of the technology. Let’s explore each of them one-by-one. 

We’d like to breakdown the entire working into 3 main processes:

1. Video and Audio Compression 
2. Streaming Protocols
3. Network and Transmission

Here is the a detailed note one each process:

1. Video and Audio Compression

Before a stream is transmitted, their data must be processed and brought down to smaller chunks to avoid speed and performance degradation. This is where you’ll need to focus on compressing both the video and audio data. 

To do this, you’ll need the following:

1. Codecs
2. Bitrate management 

1. Codecs

Codecs are the hardware- or software-based processes that compress raw audio and video data before transmission and decompresses it for playback. Both these processes are important to significantly reduce the amount of data that needs to be sent over the network. 

If the data is not compressed, huge chunks of data might have to be transmitted, which will slow down the streaming, and cause serious performance issues. 

To do this you’ll need 2 different codecs.

• Video Codecs 
• Audio Codecs

Video Codecs

• H.264 (AVC): Most often mobile apps use this codec to achieve a good balance between compression efficiency and computational requirements. 
• H.265 (HEVC): Want a more advanced codec that’s 50% better than H.264? You’ll need the H.265 codec, which handles compression and maintains quality. However, while this codec requires more processing power and might affect battery life on mobile devices, it performs efficiently on CTV devices, providing a high-quality streaming experience on larger screens without significant impact on performance.
• VP9: This is an open-source codec developed by Google that is primarily used on YouTube. It offers compression efficiency similar to H.265 but the licensing costs are comparatively low. 
• AV1: This codec was developed by Alliance for Open Media. It promises even better compression when compared to H.265 and VP9, on the other hand, it requires significant computational resources.

Audio Codecs

• AAC (Advanced Audio Coding): AAC is an audio codec for streaming that offers excellent sound quality at relatively low bitrates. It’s particularly effective for music and speech.
• Opus: This is an open-source codec that excels in both speech and music compression. It offers low latency and a wide range of bitrates, making it adaptable to varying network conditions.

2. Bitrate Management

Bitrate management in live streaming is about controlling the amount of data sent per second. This is very important for delivering smooth video to viewers whatever be their internet speed. 

Streaming platforms use adaptive bitrate, which adjusts video quality based on the viewer’s connection. 

• Higher bitrates mean better quality but require faster internet. 
• Lower bitrates work on slower connections but reduce video quality. 

The goal ultimately is to find the right balance between quality and stability. This is where we’ll useeEncoders compress the video in real-time, so that we can achieve the best possible quality within the chosen bitrate. 

Some platforms automatically adjust bitrates, while others let streamers set them manually. Overall, good bitrate management makes sure that your viewers get the best possible experience without buffering or lag.

Here are 2 different ways you can manage bitrate streaming. 

• Adaptive Bitrate Streaming (ABR)

ABR is a method where the streaming solution is set to automatically adjust the quality of a video stream real-time based on the viewer’s available bandwidth and CPU capacity. 

This is undoubtedly the best way to make sure that viewers enjoy the highest quality stream without much buffering and interruptions.

• Bitrate Ladder

This one is an old-style way of controlling the number of bits used per second.

A bitrate ladder includes a collection of different encodings at varying quality levels and bit rates for the same video content.

For instance, a ladder could include a 360p version, a 720p version, and a 1080p version of the same video file at different data rates.

The streaming client has the capability to switch between those different editions without interruption so that it offers optimal watching experience regardless of changes in internet speed or bandwidth.

2. Streaming Protocols

• HLS (HTTP Live Streaming)

HLS, the live streaming protocol, developed by Apple stands as one of the most supported protocols for live streaming. 

Now, what’s the deal with how it functions? It splits the whole stream into a series of small file downloads using HTTP. 

Each file has a brief playback time from the full stream. While it’s great for compatibility and can adjust bitrates, it adds more delay (10-30 seconds) than RTMP.

• RTMP (Real-Time Messaging Protocol)

Macromedia first made RTMP for their Flash Player, and people still use it a lot to send live streams to servers. 

It has a short delay (2-5 seconds) but doesn’t work well for playback on many mobile devices.

• WebRTC (Web Real-Time Communication)

WebRTC is a free open-source project that lets web browsers and mobile apps communicate in real-time through simple APIs. 

It aims to have very little delay (less than a second) for direct communication between users. And that is why it is perfect for video conferencing and interactive live streams.

• SRT (Secure Reliable Transport)

SRT, an open-source video transport protocol, helps to improve streaming performance on unreliable networks during live broadcasts. 

It works well to deliver high-quality video even when the user’s network quality is poor. SRT also offers other advantages such as the ability to recover lost packets, encrypt data, and keep an eye on network health.

• DASH (Dynamic Adaptive Streaming over HTTP)

Just like HLS, DASH allows high-quality streaming of media content over the Internet from regular HTTP web servers. It adapts the bitrate to suit the viewer’s connection strength. 

One fascinating thing about DASH is, it works with any codec and supports smooth streaming of both on-demand and live content.

3. Network and Transmission

1. Error Correction and Packet Loss Recovery

No one can avoid packet loss when the internet condition is quite unpredictable. But there are 2 main techniques that are commonly used to mitigate this:

• Forward Error Correction (FEC): This method adds extra data to the live stream. 

It helps the receiver rebuild lost packets without asking for them again plus it sends more data overall, but can cut down on any noticeable delays when the network drops packets.

• Automatic Repeat reQuest (ARQ): This is a reactive approach involving the receiver requesting retransmission of lost packets. 

ARQ renders perfect reconstruction of the original data, it can introduce additional latency.

2. Content Delivery Networks (CDNs)

CDNs play a key role in live streaming setups that are really big. They spread servers across different locations to store and deliver content. 

When someone wants to watch a stream, the nearest CDN server sends it, cutting down on delay and making the stream actually look better.

• Multi-CDN Strategies

To make things even more reliable and faster, many streaming services use multiple CDNs. 

This means they work with several CDN providers and send viewer requests to the CDN that’s performing best at that moment, based on real-time data.

3. Edge Computing

Edge computing moves data storage and computation nearer to end-users cutting down on delays and bandwidth usage. 

For live streaming, edge computing helps with tasks such as real-time video transcoding, packaging, and content moderation. You know? This leads to quicker and more effective content delivery when compared to other technologies. 

Low Latency: A Key Factor In In-app Live Streaming 

Low latency refers to the time difference between an event happening at the source and viewers seeing it on their screens. In live streaming reduced latency makes the experience feel more ‘live’ and closer to real-time. 

Latency plays a very important role in interactive events and when quick information delivery is really the focus of the business. 

The effect of low latency extends beyond user satisfaction – it has an impact on stream engagement, performance, and even the core purpose of some streaming applications. 

Here’s why your live streams need to have low latency:

• Provides a more immersive and “live” feeling for viewers
• Reduces frustration caused by noticeable delays
• Allows for timely responses to comments and questions
• Can be a key selling point for your streaming service
• Keeps viewers more engaged and connected to the content
