package main

import "C"
import "github.com/Tryanks/go-rkcodec"

func main() {
    decoder := rkcodec.NewMppCodec()
    decoder.Control(rkcodec.MppDecSetParserSplitMode, C.int(1))
    decoder.Init(rkcodec.MppCtxDec, rkcodec.MppCodingAVC)

    frame, err := rkcodec.MppFrameInit()
    if err != rkcodec.MppSuccess {
        panic(err)
    }
    defer frame.Deinit()

    packet, err := rkcodec.NewMppPacket()
    if err != rkcodec.MppSuccess {
        panic(err)
    }

    h264NALU := make([]byte, 1024) // H.264 NALU data

    packet.SetData(h264NALU)

    err = decoder.DecodePutPacket(*packet)
    if err != rkcodec.MppSuccess {
        panic(err)
    }

    err = decoder.DecodeGetFrame(frame)
    if err != rkcodec.MppSuccess {
        panic(err)
    }

    // Do something with the frame
