Rounding out Figure 2, video delivered via progressive streaming is typically enabled via a single encoded file. As you can see in Figure 2, CMAF was supported by 21% of respondents in 2021, but 36% of respondents plan to adopt it in 2021. Rather, itРІР‚в„ўs a technology that allows producers to create one set of files they can deliver to multiple ABR delivery technologies, including HLS, DASH, Smooth Streaming, and HDS. As explained in more detail below, CMAF isnРІР‚в„ўt an ABR technology. The Common Media Application Format (CMAF) is a standards-based container format launched in 2018. Adobe introduced HTTP Dynamic Streaming (HDS) in 2010, though it never really caught on and today is only supported by 5% of Bitmovin respondents. Microsoft shipped their own HTTP-based ABR technology called Smooth Streaming in 2008, which is still supported by 24% of survey respondents, mostly to support game platforms like the Xbox. This cuts the implementation cost over RTMP technologies that require a server, improves scalability, and because HTTP packets arenРІР‚в„ўt blocked by firewalls, improves delivery reliability.

Since both of these technologies are HTTP-based, they can run on a plain HTTP web server without a streaming server. HLS is followed by the MPEG standard Dynamic Adaptive Streaming over HTTP (DASH) which shipped in 2012. Most prominent is AppleРІР‚в„ўs HTTP Live Streaming (HLS ), which launched in 2009 and accounts for the lionРІР‚в„ўs share of ABR streaming today. Though there are alternatives, most new ABR deployments are based upon HTTP-based ABR technologies. They also rely upon the Flash player, which was end-of-lifed by Adobe in January 2021. ABR formats deployed per the 2020 Bitmovin Video Developer Report RTMP-based technologies require a server to communicate with the player which makes them more expensive to implement, and some firewalls reject RTMP packets which can cause delivery issues.Р”Р‡igure 2.

As you can see in Figure 2, from the Bitmovin 2020 Video Developer Report, approximately 36% of survey respondents continue to use RTMP-based ABR streaming, with 13% planning to implement RTMP-based streaming in 2021. As shown in Figure 1, however, the YouTube Player, many also allow the viewer to choose the stream to be viewed.Р”Р„BR streaming achieved mass-market success as a technology deployed by Adobe using the Flash Media Server and compatible products using the RTMP protocol. Most ABR technologies work automatically without user input.

YouTubeРІР‚в„ўs implementation of ABR streaming uses a six-rung ladder and can work in either auto or manual mode.

This allows ABR technologies to deliver an optimum viewing experience to those watching on a range of devices over many different connection speeds.Р”Р‡igure 1. ABR technologies adapt in at least two ways sending different files in the encoding ladder to different devices depending upon their playback capabilities and adapting the file sent to a particular client to changing bandwidth conditions. You can deliver a single set of CMAF files to multiple ABR formats (not my diagram РІР‚вЂњ if itРІР‚в„ўs yours, ping me at and IРІР‚в„ўll add the credit).Р”Р„BR technologies encode live and on-demand videos into multiple files (called an encoding ladder) for delivery to a range of playback devices connecting via different speeds. Enter the Common Media Application Format (CMAF).
