- streamID
-
UInt32
unsigned int
uint32_t
正在分析的媒体流的标识符。
- streamType
- NDMediaStreamType
媒体流的类型。 此值可以是 “音频” 或 “视频”。
- streamSample
- MediaStreamSample
流样本的数组。
- pts
-
Int64
long long
long
表示时间戳，指示何时播放示例（以毫秒为单位）。 此值相对于演示文稿中的先前示例。 例如，如果给定的样本的演示时间戳为 1000，而一些后续示例的演示时间戳为 2000，则后面的样本在给定样本后 (1000 毫秒) 发生一秒。
- ccFormat
- NDClosedCaptionFormat
关闭描述文字格式。 此值可以是 ATSC、 SCTE20 或 Unknown。
- ccDataBytes
-
Byte[]
byte[]
包含闭合描述文字数据的数组。
