Types

type AVPacket

type AVPacket struct {
	Timestamp   uint32
	PayloadType int
	Payload     []byte
}

目前供package rtsp使用。以后可能被多个package使用。 不排除不同package使用时，字段含义也不同的情况出现。 使用AVPacket的地方，应注明各字段的含义。

type RTMPHeader

type RTMPHeader struct {
	CSID         int
	MsgLen       uint32 // 不包含header的大小
	MsgTypeID    uint8  // 8 audio 9 video 18 metadata
	MsgStreamID  int
	TimestampAbs uint32 // 经过计算得到的流上的绝对时间戳
}

type RTMPMsg

type RTMPMsg struct {
	Header  RTMPHeader
	Payload []byte // 不包含 rtmp 头
}
