How low can you go? Not low enough. At least with HLS that is. The engineers over at Periscope have described their process for getting HLS latency down from 10 seconds to between 2-5 seconds using a technique they call Low-Latency HLS (LHLS). Two seconds? I mean that's kinda low. Sort of like your friend who does an "awesome" Darth Vader impression. It's all well and good but there's only one James Earl Jones. As we discussed in our last post, there are a great number of low-latency applications, and the demand for them is always growing. The…

WebRTC is enjoying an ever-expanding influence over the tech market in general and live-streaming specifically. From increased security to plug-in free communication, we've covered the many benefits of WebRTC. However, not all platforms support it. As a server-side media processor, Red5 Pro can effectively handle streams from different sources and networks so that video and audio sessions can be launched with any device. This is why Red5 Pro built failover support into our WebRTC implementation. When publishing or subscribing with a WebRTC application, any platform that does not support WebRTC will failover to Flash (RTMP) or HLS. So How Does…

Jetpacks have been a mainstay for starry-eyed dreamers and futurists for a long time. Despite the occasional story from some engineer a-la stunt-double, that potential continues unrealized, a mere daydream of all those frustrated commuters stuck in traffic. At Red5 Pro, we're also focused on the future and strive to build it (albeit more concretely). As such, we actively appraise and adopt ground-breaking technologies that have both real-world impact and promising potential. Take for example, our WebRTC implementation. WebRTC has been gaining widespread use and has made large strides in creating interoperability between browsers. With Apple's progress on integrating WebRTC…

Live video streaming is taking off like crazy, and you want to get in on this new technology by building your own cat streaming app. "Periscope for Cats will be the next big thing" you say. You start looking into what's out there for a software developer to build on, and immediately are inundated with way too many choices. One of the biggest points of confusion we see from newcomers to live stream programming is: "what is the best protocol to use for my app?". Just this week I wrote an answer to this really great…

Dan Rayburn recently wrote a blog post stating that Content Delivery Networks are quickly moving away from the Flash streaming protocol RTMP. I've been hearing this from a number of our customers as well, and I agree that this is the direction that the CDN industry is taking. The solution that they all seem to be moving towards is HTTP based protocols like HLS and MPEG-dash. This is great for them because HTTP is way easier to support at scale, and it's widely supported across a huge number of players/clients. As I've written before though, HTTP based protocols come…

HLS, or HTTP Live Streaming is a video streaming format first introduced by Apple in May, 2009. It’s a format that breaks streams into small file-based segments made available for download over HTTP. It now is a widely supported format for viewing streams in almost real time. I say almost only because the protocol, by its very nature, introduces a lot of latency. We’ve been getting a lot of questions and inbound interest from our customers about HLS. What are the advantages of using it? What are the disadvantages? How does HLS compare to WebRTC? Will Apple approve…

We have been working hard on a number of features that we are super excited about including clustering and HLS support. You can get the new release here. Make sure to be signed in with your account first. Also, expect new SDKs to follow soon as well. Cheers! RED5 PRO SERVER 0.2 RELEASE NOTES This release has two new features our customers have been requesting. CLUSTERING This version of the server allows for configuring servers together to achieve infinite scale. This is the first version of the feature and is limited to round robin style load balancing of Edge…
