AV1 can deliver the same picture quality as H.264 at about half the bitrate. For a live service, where delivery traffic grows with every viewer, that is the most direct way to cut CDN costs. And you do not have to change how you broadcast: keep sending H.264 from OBS or your existing encoder, and let OvenMediaEngine convert it to AV1 for viewers.

If you are evaluating AV1 for a live service on OvenMediaEngine (OME), this post walks you through the numbers, the hardware you need, and a working configuration for LL-HLS and WebRTC.

We are living in an era where anyone can easily broadcast content. In the past, broadcasting was limited to television stations, but now, with the power of smartphones and computers, anyone can effortlessly stream their content to the world. Streaming platforms and services have revolutionized the way we consume media, offering creators a convenient and fast way to share their creations with the world.

The pandemic has forced people to stay indoors, significantly changing today’s digital content consumption patterns. Many individuals have become aware of the latency issues in traditional streaming services and are now seeking digital content that can provide immediate responses.

This is the 4th session of the Metadata series, and let me explain Audio Metadata. Note that this article is talking about the basics of audio metadata, not a reference to professional audio technology.

This is the third session of the Metadata series. First, let’s study the Aspect Ratio. Aspect Ratio means the ratio of the screen. However, the ratio of the screen is a different concept from Frame Size that we learned before. While the Frame Size is the length of the width and height, the Aspect Ratio is the ratio of the width and height based on the size determined by the Frame Size.

Today, we will talk about Frame Size following Frame Rate. The** Frame** is defined as one still image. The word Size is combined with the frame, so you can see that the phrase size means the video screen size.

Today, we would like to talk to you about **Frame rate **(Framerate, Frame-rate), one of the factors making up a video, and it has always been used when we are shooting, encoding, streaming, or even playing. Frame-rate is a word combining two words — frame and speed.

What are Property and Asset?

Everyone has a rough idea of the media asset. But it’s hard to tell precisely, “Hey! listen carefully, and the media asset is this!” This is applied to me as well. So, before talking about media assets, we should know the general concept of property and assets first.

When you watch a live broadcast on the Internet, it usually takes 6 to 20 seconds to view the scenes delivered by the streamer. Even if you send a chat message now to the streamer, you can’t see the streamer’s response unless 6 to 20 seconds have elapsed. Therefore, you should keep watching for 6 to 20 seconds after sending a chat message so that you can communicate with the streamer. The chat message is in text format, sending it immediately, but the streamer responds with a video stream, so it takes 6 to 20 seconds to reach you. This situation is called Latency.
