index=2
codec_name=unknown
codec_long_name=unknown
TAG:language=chi
TAG:title=中文（简体）
index=3
codec_name=unknown
codec_long_name=unknown
TAG:language=chi
TAG:title=中文（繁體）

index=2

codec_name=unknown

codec_tag_string=[0][0][0][0]

codec_tag=0x0000

index=3

codec_name=unknown

codec_tag_string=[0][0][0][0]

codec_tag=0x0000

in this case，the sever cannot recognize and render the subtitle.
