Low latency remains a key component in any live streaming application. Video chat, distance learning, live auctions, event broadcasts and many more use case cases all need fast stream delivery to ensure a positive user experience. The challenge lies in providing low latency that is consistent and scalable. Complicating matters further, is the fact that live streaming video is itself nuanced with many subtle yet impactful considerations that must be taken into account. In order to simplify this process and cut through any confusion, Red5 Pro and Videon have joined forces to bring real-time latency live video streaming to the…

Creating a fully functioning Android live streaming app can be complex. You have to configure all of the backend system infrastructure required for a basic web application, plus all the additional considerations (i.e. potential pain points) for native app integration. Accordingly, some live streaming software companies have added mobile SDKs to their offerings in order to make that process easier. Why build something from scratch and needlessly spend extra money and time to recreate something that already exists? However, it does need to work well, lest all that saved money and efforts will go right back into fixing everything.…

Content Delivery Networks (CDNs) are a popular way that many video streaming services send out their video so it can be watched by all the people that want to see it. CDNs work by caching information on the various data centers they have distributed across the globe. As each data center is a server, it could be said that each CDN is made up of a series of CDN Video Streaming Servers. Akamai, one of the largest CDN providers, defines a video streaming server this way: “A video streaming server delivers video content over the Internet to a user with…

Building a live streaming application requires many moving pieces. Not only is the process of live streaming complicated, but the number of companies offering to help “simplify” the process can have the opposite effect. Let’s take a look at some of the key features you should consider in choosing a platform to build your live streaming application on. 1) LatencyHaving the lowest possible latency is a keystone to live experiences. Live auctions, drone guidance, event broadcasts, even basic conversations all need real-time latency. Any sort of delay between the broadcaster and subscriber will have negative consequences. High latency results…

When the internet was born only few people would have imagined the amount of data that it would need to handle decades later. The Internet and its original protocols were designed to send small packets of data (like emails) that could traverse the network and go from computer A to computer B. Nowadays, Internet traffic has evolved to include the delivery of video. Not only is video a part of internet traffic, it far exceeds all other content. Cisco estimated that by 2022 82% will consist of Internet Protocol (IP) video content while the sum of all forms of IP…

The recent shift of most office environments to a completely online platform has resulted in a substantial increase in the use of the conferencing platform Zoom, However, this increased use has also resulted in increased scrutiny which has revealed some of Zoom’s shortcomings. A major issue in security has recently come to light resulting in bans from school districts, SpaceX and the FBI. Stream security is not as tight as it should be resulting in people easily hacking into stream URLs and disrupting meetings. Some disruptions are mostly playful interruptions from bored teenagers, but some are much more insidious,…

As much as the coronavirus has wreaked uncertainty around the world, educating students remains something that is very important. The question lies in how to educate while avoiding the gathering of people at a school. The most logical way is to move to a virtual classroom and teach through video chat applications, otherwise known as distance learning. Some educators have turned to the popular application Zoom to conduct distance learning classes. However, Zoom was built as a general-purpose conferencing tool. Some teachers and students are discovering that it doesn’t always work as well as they would like. It’s…

As the novel coronavirus (COVID-19) has spread across the world, it has severely impacted businesses. Most companies depend upon some form of face to face interaction to conduct business. That means that the social distancing, quarantine periods, and crowd restrictions required to stem the spread of the virus have disrupted a wide variety of different industries. The obvious benefactors of home quarantine are streaming services such as Netflix, but there are others that have benefited as well. While the full coronavirus business impact is still emerging, we know the severe issues it is currently creating. This post examines some of…

Now, more than ever, live-streaming is important due to how the coronavirus is forcing businesses and people to limit physical interactions. However, implementing a live streaming solution remains a (potentially) daunting task. There are a lot of moving pieces which means there are many places where things can go wrong. Further complication comes from the fact that your live streaming setup may need to be adjusted according to the type of event being broadcast. Fortunately, there are a few people out there who have devoted their lives (professional and otherwise) to live streaming. Join some of them (including our Technical…

Live video substantially increases user engagement. This fact has dramatically increased the growth of the live video streaming industry. The rise of popular social video streaming apps like Periscope, Tik Tok or Facebook Live, along with live e-Sports and video games broadcasts like Twitch, prove the value of interactivity which can only be attained through real-time latency. With this in mind, the current low latency streaming solutions can be divided into two categories of latency: those that are within a two to three second range (not practical for true interactive use cases), and others in the sub-second or real-time category.…

Red5 Pro Release 6.2.0

Though our latest release was a big one, that certainly doesn't mean we took any time off. Following the big release of Red5 Pro version 6.0 comes 6.2! This update improves shared objects behavior and introduces the inspector webapp. The inspector allows you to get details about your stream in real-time for diagnostic purposes. While Chrome's WebRTC internals gives a tremendous amount of data on live streams from the client side perspective, the Inspector by contrast gives you details about the published stream coming into a Red5 Pro server. The Inspector evaluates the latency of a published stream…

Both RTMP and RTSP have a long-established foothold in media delivery technology.  They helped develop the internet into the transformative information sharing platform that it is today. However, there are a variety of uses when it comes to RTMP vs. RTSP.   What is RTMP? RTMP (Real-Time Messaging Protocol) is an application-level video streaming protocol with a long history in the media streaming marketplace. Developed by Macromedia and now owned by Adobe, RTMP was designed for the delivery of on-demand and live media between a Flash player and a Media Server over the Internet. While the Flash player is quickly being…

Last week we teamed up with Brightcove and hosted the Boston streaming video meetup at our Boston offices. This was intended as an intro to video streaming technologies and the various approaches to reducing latency. Thiago Teixiera, Alex Barstow, and Chis Allen all presented on three different approaches to live streaming latency: HLS, CMAF, and WebRTC. As we’ve covered before, live streaming latency in video comes from all the complexity involved in sending large amounts of data over the internet. No matter which way you choose to stream your video, there are some things you have to do no…

In 1996, people browsed the Internet(s) with Netscape Navigator, still did searches via Yahoo (not to mention AltaVista) and the first flip phone was the coolest gadget available. ‘96 also marks the year of RTSP’s creation. While many of its technological peers have fallen into disuse (remember the Gopher protocol?), RTSP has still somehow managed to stay relevant. The question is: why? How, in the ever-changing tech world, has RTSP survived?  This post presents four reasons. What is RTSP?First, let’s examine the roots of RTSP. The Real-Time Streaming Protocol (RTSP) is a network control protocol designed…

AV1 is a new video codec with a very promising –and this cannot be emphasized enough– future. The buzz around AV1 centers upon its ability to more effectively compress video. This is really exciting for large VOD based companies like Netflix as AV1 can reduce bandwidth requirements by 30-50% beyond currently employed codecs. Being able to stream the same content while paying for less data is important for VOD and OTT applications. However, for live video use-cases concerned with latency (i.e. everything not VOD), bandwidth is only a part of the equation. This brings us to our main point:…

It’s been a long time coming. Flash is well on its way out with 2020 marking the last official year for support. Flash was a cornerstone of the live-streaming technology sector and, with the use of the underlying RTMP protocol, lay the groundwork for where we are today. The general-purpose streaming platform Justin TV was powered by Flash before it turned into the game streaming platform Twitch. As demand for live video grew, Flash's limitations (plugin-in dependent, proprietary technology, performance issues, etc.) proved an impediment to the advancement of live-streaming. It is worth mentioning that Flash also served as…

RTMP (Real-Time Messaging Protocol) has a long-established history as one of the original methods for live streaming.  Originally developed by Macromedia and now owned by Adobe. RTMP was designed for delivering on-demand media and live media (i.e live audio, video, and data) over the Internet between a Flash player and a Media Server. However, there are big changes coming for Flash... in that it’s going away. The new year of 2020 marks the last year of official Flash support. By losing Flash, we also lose the ability to run RTMP in internet browsers. That leads to the question…

History RTMP (Real-Time Messaging Protocol) is an application-level video streaming protocol originally developed by Macromedia and now owned by Adobe. With a long history in the media streaming market, RTMP was originally designed for delivering on-demand media and live media (i.e live audio, video, and data) over the Internet between a Flash player and a Media Server. Without Flash, we more than likely wouldn’t have low-latency video communication through WebRTC, nor would Internet video protocols like HLS and MPEG-DASH be so prevalent. Flash Player was the dominant usage of RTMP for a long time. At one point, Flash…

Functionality of RTSPThe Real Time Streaming Protocol (RTSP) is a network control protocol designed for use in entertainment and communications systems to control streaming media servers. Developed by experts from RealNetworks, Netscape and Columbia University around 1996, the protocol is used for establishing and controlling media sessions between end points. Clients of media servers issue “remote control” style commands, such as play (when to begin delivery), record, and pause. This facilitates real-time control of the media streaming from the server to a client. More specifically, RTSP is used by the client application to communicate to the server information such as…

Content Delivery Networks (CDNs) are geographically distributed networks of proxy servers and data centers (caches). Emerging in the ’90s as a way to ease some of the bottlenecks in media delivery (websites, video, etc.), CDNs work by caching information. To summarize the way a CDN works: Every time website visitors and application users request for content (e.g., play a video, open a blog post, enlarge a picture) a CDN transmits the data to the closest server to them rather than the original server where the content is hosted. This is done through the use of edge servers that sit…

Nginx is open-source software for web serving, reverse proxying, caching, load balancing, media streaming, and more. It was originally created as a web server for delivering websites and has evolved into a multifaceted solution for proxying content. Today it’s the most widely deployed web server. Eventually, NGINX added RTMP support to address scalability problems with plain RTMP streaming. That provided good performance and stability for live streaming over less scalable solutions like Flash Media Server and Wowza. RTMP (Real-Time Messaging Protocol) is an application-level protocol owned by Adobe.  It was originally designed for delivering on-demand media and live media…
