RFC 4646 language tag

On Apple Devices, elng determines how the player displays the mp4 track name.

Tags list: https://www.iana.org/assignments/language-subtag-registry/language-subtag-registry

Here are some common tags:

Elng	Display Name (简体中文系统显示)
zh-CN	中文
zh-Hans	简体中文
zh-Hant	繁体中文
zh-Hant-TW	繁体中文（台湾）
zh-Hant-HK	繁体中文（香港）
en-US	英文
...	...
...	...

You can also use some trick to make player show clear track name. For example, different audio codecs (Dolby Digital Plus and AAC) in the same language are not distinguishable by default, you can set elng like this:

elng=zh-DDP => 中文（DDP）
elng=zh-AAC => 中文（AAC）

Apple Devices Tips

• HEVC tag must be hvc1 or dvh1
• Timed text hdlr set to sbtl
• Video tracks, audio tracks and subtitle tracks in different alternate group
• Display name depends on the extended language tag instead of reading the name property of udta as most players on Windows do

Todo

• Dual layer DoVi
