HLS 支持哪些音频编解码器?

Which audio codecs are supported for HLS?

HLS 协议是否指定音频编解码器?如果支持,支持哪些?

我尝试搜索,但找到了不同的列表:

MP3, HE-AAC or AC-3

根据wikipedia

AAC, AAC-LC, HE-AAC (accPlus) v1 & v2, MP3

根据this

AAC-LC, HE-AACV1-2, AC-3, and EC-3

根据FairPlay overview(HLS 的子集)

我会参考 HLS 规范。来自 section 3.4:

Supported Packed Audio formats are AAC with ADTS framing [ISO_13818_7]; MP3 [ISO_13818_3]; AC-3 [AC_3]; and Enhanced AC-3 [AC_3].
