WeвЂ™re going to cover three scenarios, all working with the same segmented video streams.

We wonвЂ™t spend a lot of time on video encoding in this tutorial, but as an overview, our 1080p source video was encoded into eight video-only variant streams, each of which were segmented into multiple MPEG-2 transport stream chunks using AppleвЂ™s Media File Segmenter, which also created an M3u8 playlist for each variant.

You can find system compatibility information for many systems and devices at the Dolby Developer website. and optionally, a legacy Dolby Digital 5.1 stream to maintain compatibility with older systems that donвЂ™t support Dolby Digital Plus. YouвЂ™ll also want to produce an AAC stereo stream for systems without Dolby support. If you start from a surround sound audio source, youвЂ™ll typically create two encodes in Dolby Digital Plus format a stereo encode for optimized delivery to stereo devices like iPhones and iPads, and a multichannel encode for systems that support it, like Apple TV. Because of its advanced features, itвЂ™s a good idea to make Dolby Digital Plus the preferred audio format on platforms and devices that support it.

Also called EC3В or E-AC-3, Dolby Digital Plus produces clear and powerful sound for a remarkably versatile set of outputs, from stereo headphones and speakers to 7.1 surround sound systems.Д«oth Dolby Digital Plus and Dolby Digital are supported natively across iOS, macOS, and tvOS, as well as MicrosoftвЂ™s Windows 10 platform. It is supported in HLS for compatibility with systems that donвЂ™t support native Dolby playback.Дolby Digital, also known as AC-3, is an advanced, metadata-rich audio format that can deliver up to six channels of audio at data rates between 384 and 640 Kbps.Дolby Digital Plus, evolved from Dolby Digital, is a more capable audio format that brings higher audio quality, lower data rates, more powerful metadata-driven features and support for 7.1 audio channels. Let's start with a brief discussion of audio formats.ДЄACВ is a widely deployed audio codec in online video, often used as a baseline stereo audio codec.

But you can read up on these materials in this post on the Dolby Developer blog, which also provides full access to the various master playlists youвЂ™ll learn to create, as well as the actual HLS video clips they enable, and the presentations you'll see in these videos.ДЇor more information HLS encoding in general, check out Apple's HLS Authoring Specification on the Apple Developer site. ThereвЂ™s a lot of detail in all presentations and they move pretty fast.

In the third tutorial, youвЂ™ll learn how to segment your streams and create media playlist files with AppleвЂ™s Media File Segmenter, and how to create the master playlist file that tells the playback client what audio formats and variants are available, including how to support multiple languages.ДЇinally, you will learn how to validate your streams with AppleвЂ™s Media Stream Validator tool. In the second tutorial, youвЂ™ll learn how to measure audio loudness and how to encode files in Dolby Digital Plus, Dolby Digital, and AAC formats to support all devices and audio end points. In the first tutorial, weвЂ™ll provide an overview of the workflow and show examples of the tools youвЂ™ll need to get the job done.

Over the course of this three-part tutorial series, weвЂ™ll show you how to do just that. Since the release of iOS 10, tvOS 10, and MacOS Sierra, you can now deliver Dolby Audio via HLS and play it back on any audio endpoint, including device speakers, headphones, or external sound systems via AirPlay or HDMI. This video tutorial series is sponsored by Dolby.Дolby Audio is a family of premium sound format(s) that provides enhanced clarity, easy-to-hear dialogue, consistent volume, and also surround sound when played on a 5.1 or 7.1 channel system.
