Summary

TLDR;

This document is an EXT-X-MEDIA playlist file that specifies various media streams for a video, including subtitles, audio, and video resolutions. It includes multiple options for each, such as different languages for subtitles and audio, and various resolutions and bitrates for video, using both AVC and HVC codecs.

  • The file provides URLs for subtitles in multiple languages like German, English, Spanish, French, Japanese, Korean, Portuguese (Brazil), and Chinese.
  • It offers audio in English with stereo AAC and Atmos EAC3 formats, including audio descriptions.
  • The video streams are available in SDR (Standard Dynamic Range) with AVC and HVC codecs, resolutions from 360p to 2160p, and various bitrates.

Subtitle Options

The playlist includes subtitle options in multiple languages. These are defined using the #EXT-X-MEDIA tag with TYPE=SUBTITLES. The available languages are:

  • Deutsch (German)
  • English
  • Español (Spanish)
  • Français (French)
  • 日本語 (Japanese)
  • 한국어 (Korean)
  • Português (Brasil)
  • 简体中文 (Simplified Chinese)

Each subtitle option has AUTOSELECT=YES and FORCED=NO, meaning they can be automatically selected by the player but are not forced to display.

Audio Options

The playlist provides several audio options, specified using the #EXT-X-MEDIA tag with TYPE=AUDIO. These options include:

  • English Stereo AAC: Standard stereo audio encoded with AAC at 128 kbps.
  • English Atmos EAC3: Immersive audio encoded with EAC3 at 640 kbps, providing a 16-channel (16/JOC) experience.
  • English Audio Descriptions: Both stereo AAC and Atmos EAC3 versions are available, designed to provide descriptions of the video content for accessibility. These are marked with CHARACTERISTICS="public.accessibility.describes-video".

Both main audio and audio description tracks are available in stereo AAC and immersive Atmos EAC3 formats.

SDR AVC Video Streams

The playlist lists several video streams encoded with the AVC (Advanced Video Coding) codec in Standard Dynamic Range (SDR). These streams are defined using the #EXT-X-STREAM-INF tag and include various resolutions and bitrates:

  • 540p @ 2000 kbps: 960x540 resolution with an average bandwidth of 1559625 kbps.
  • 360p @ 600 kbps: 640x360 resolution with an average bandwidth of 610728 kbps.
  • 360p @ 1200 kbps: 640x360 resolution with an average bandwidth of 911738 kbps.
  • 720p @ 3000 kbps: 1280x720 resolution with an average bandwidth of 2330671 kbps.
  • 720p @ 4500 kbps: 1280x720 resolution with an average bandwidth of 2727640 kbps.
  • 1080p @ 6000 kbps: 1920x1080 resolution with an average bandwidth of 4646796 kbps.
  • 1080p @ 8500 kbps: 1920x1080 resolution with an average bandwidth of 5531793 kbps.

Each AVC stream has corresponding I-frame stream information for trick-play functionality.

SDR HVC Video Streams

The playlist also includes video streams encoded with the HVC (High-Efficiency Video Coding, also known as HEVC or H.265) codec in SDR. These streams offer similar resolutions to the AVC streams but generally at lower bitrates due to the increased efficiency of the HVC codec:

  • 540p @ 1930 kbps: 960x540 resolution with an average bandwidth of 1017662 kbps.
  • 360p @ 1090 kbps: 640x360 resolution with an average bandwidth of 591684 kbps.
  • 720p @ 2900 kbps: 1280x720 resolution with an average bandwidth of 1566995 kbps.
  • 720p @ 4080 kbps: 1280x720 resolution with an average bandwidth of 1640883 kbps.
  • 1080p @ 5400 kbps: 1920x1080 resolution with an average bandwidth of 2934739 kbps.
  • 1080p @ 7000 kbps: 1920x1080 resolution with an average bandwidth of 3113669 kbps.
  • 1440p @ 8100 kbps: 2560x1440 resolution with an average bandwidth of 4605810 kbps.
  • 2160p @ 11600 kbps: 3840x2160 resolution with an average bandwidth of 7832289 kbps.
  • 2160p @ 16800 kbps: 3840x2160 resolution with an average bandwidth of 9710987 kbps.

Like the AVC streams, each HVC stream includes corresponding I-frame stream information.
