问题

能够提供一个H264 新接口的编码DEMO ?

背景

#旧接口--可正常使用
DPRCT_W virtual int encode(const void* inputBuf, unsigned int inputLen,
                               void* outputBuf, unsigned int outputLen) = 0;

# 新接口
virtual int encode(AVPacket* inPacket) = 0;

使用上述接口编码NV12->H264. 可以正常工作. 但根据官方提示, 该接口已废弃. 推荐使用新的接口

新接口问题描述

// init part

 if (!m_avPacket )
    {
        m_avPacket = (AVPacket*)calloc(1,sizeof(AVPacket));
        if (!m_avPacket->pAddrVir0)
        {
            int32_t frameSize = encode_param_.srcW * encode_param_.srcH *1.5;
            m_avPacket->pAddrVir0 = (unsigned char* )calloc(frameSize, sizeof(int8_t));
            m_avPacket->pAddrVir1 = m_avPacket->pAddrVir0+ encode_param_.srcW * encode_param_.srcH;
        }    
    }

 p_encoder_ = AWVideoEncoder::create();
  p_encoder_->init(&encode_param_,this);


int32_t Encoder::EncodeFrame(int8_t *buff, uint32_t buffSize, int64_t pts, int32_t format)
{

    if (buff == NULL || !m_avPacket)
    {
    	PLOGE.printf("raw image data is null and return!\n");
    	return -1;
    }
    static int64_t frameIndex  =0;
    m_avPacket->id = frameIndex ++;
    m_avPacket->pts = pts;
    int32_t frameUint = encode_param_.srcW * encode_param_.srcH ;
    m_avPacket->dataLen0  = frameUint;
    m_avPacket->dataLen1  = frameUint/2;
    memcpy(m_avPacket->pAddrVir0 ,  buff,frameUint*1.5);
    // memcpy(m_avPacket->pAddrVir1 ,  buff+frameUint,frameUint/2);
    int32_t ret =  p_encoder_->encode(m_avPacket);
    LOGI("encode input    pts:%d , index:%d result:%d", buffSize, pts, m_avPacket->id,ret);
    
}

替换使用新的接口, 编码第二帧数据的时候, 编码器内部一直提示一下错误

ERROR  : cedarc <ReturnOneAllocateInputBuffer:424>: this buffer isn't allocate buffer,can't return
ERROR  : cedarc <ReturnOneAllocInputBuffer:390>: ReturnOneAllocInputBuffer failed

根据提示信息大意为未分配内存. 但实际输入的avpacket已经正常分配内存. 这个问题是SDKbug? 还是外部接口调用需要修改?
