USAGE

  1. 如何解析sps/pps/vps 以解析sps为例

    
//sps原始数据,不带start code(0x00000001)
var rawsps []byte = []byte{0x67,....}

//step1 创建BitStream
bs := codec.NewBitStream(rawsps)

//step2 解析sps
sps := &SPS{}
sps.Decode(bs)

  2. 获取视频宽高 以h264为例子

    //sps原始数据,以startcode开头(0x00000001)
var rawsps []byte = []byte{0x00,0x00,0x00,0x01,0x67,.....}
w, h := codec.GetH264Resolution(rawsps)

  3. 生成Extradata 以h264为例子

    
//多个sps原始数据,以startcode开头(0x00000001)
var spss [][]byte = [][]byte{
    []byte{0x00,0x00,0x00,0x01,0x67,...},
    []byte{0x00,0x00,0x00,0x01,0x67,...},
    ....
}

 //多个pps原始数据,以startcode开头(0x00000001)
var ppss [][]byte = [][]byte{
    []byte{0x00,0x00,0x00,0x01,0x68,...},
    []byte{0x00,0x00,0x00,0x01,0x68,...},
    ....
}
extranData := codec.CreateH264AVCCExtradata(spss,ppss)

  4. Extradata转为Annex-B格式的sps,pps 以h264为例子

    
//一般从flv/mp4格式中获取 extraData
//解析出来多个sps,pps, 且sps pps 都以startcode开头
spss,ppss := codec.CovertExtradata(extraData)

  5. 生成H265 extrandata

    // H265的extra data 生成过程稍微复杂一些
//创建一个 HEVCRecordConfiguration 对象

hvcc := codec.NewHEVCRecordConfiguration()

//对每一个 sps/pps/vps,调用相应的UpdateSPS,UpdatePPS,UpdateVPS接口
hvcc.UpdateSPS(sps)
hvcc.UpdatePPS(pps)
hvcc.UpdateVPS(vps)

//调用Encode接口生成
extran := hvcc.Encode()

  6. 获取对应的sps id/vps id/pps id

    //以h264为例子，有四个接口
//sps 以startcode 开头
codec.GetSPSIdWithStartCode(sps)

//sps2 不以startcode 开头
codec.GetSPSId(sps2)

//pps 以startcode 开头
codec.GetPPSIdWithStartCode(pps)

//pps2 不以startcode 开头
codec.GetPPSId(pps2)
