What features FFmpeg doesn’t provide, and How FFmpeg satisfies most of the live transcoding requirements, These variants have different bitrates so that viewers with different levels of download bandwidth are able to consume live video streams at the best possible quality for their connection.įigure 2 depicts the input and output of the transcoder module in our live video CDN. Within the live stream processing pipeline, the transcoder module is in charge of converting an incoming RTMP stream into the HLS format with multiple variants (e.g., 1080p, 720p, etc.). To then scale our live stream content to countless viewers, Twitch uses HTTP Live Streaming ( HLS), an HTTP-based media streaming communications protocol that most video websites also use. RTMP is a protocol designed to stream video and audio on the Internet, and is mainly used for point to point communication. Twitch, like many other live streaming services, receives live stream uploads in Real-Time Messaging Protocol ( RTMP) from its broadcasters. At its peak, Twitch ingests tens of thousands of concurrent live video streams and delivers them to viewers across the world.įigure 1 depicts the architecture of our live video Content Delivery Network (CDN) which delivers tens of thousands of concurrent live streams internationally. Every month, more than 2.2 million unique content creators stream or upload video on our website. Twitch is the world’s leading live streaming platform for video games, esports, and other emerging creative content. Please read part 2 after finishing this article.

Is there anything I can do to fix this? I don't think the problem is with my connection.ĮDIT: From reading more on this sub it may appear that the issue has to do with the latest Plex server update? I just updated my Windows 10 version to the latest version as well, KB4345421.By: Jeff Gong, Software Engineer, Sahil Dhanju, Software Engineer Intern Chih-Chiang Lu, Senior Software Engineer, Yueshi Shen, Principal Research Engineer, thanks go to Christopher Kennedy, Staff Video Engineer at Crunchyroll/Ellation John Nichols, Principal Software Engineer at Xilinx, for their information on FFmpeg and reviewing this article. With a 40 mbps down connection I should be able to stream a 10 mbps transcode to my understanding, however the result is choppy, skips a little, and hangs often. Now when I try to transcode a remux, the experience is bad. Recently, I've added to my library a few Remuxes that are 25 - 35 GiB in size with bit rates between 30 - 35 mbps. #Remux vs transcode movieI was always able to stream any movie I wanted through transcoding to a lower bit rate with whatever bit rate my connection was able to handle at that point in time. The encodes range in size from 10 - 18 GiB and 9 - 18 mbps. I have a server with with a 900/900 mbps connection and a library of 100 high quality Blu-Ray encodes. Hi, I'm just looking for some help/insight into a problem I'm having.
