CUDA编码结果码流转发

[想飞的笨猴]

小弟最近因为实验室项目需要，开始学习一些基于CUDA的图像压缩和转发的东西。使用的CudaSDK自带的CudaEncode示例，这个demo里面使用 NVEncodeFrame函数对图像进行逐帧压缩，把压缩的结果写进对应的H264文件，但是得不到每一帧压缩结果的字符串，想请教各位大咖，如何才能得到压缩后的字符串或者码流？

按理说得从

static unsigned char *_stdcall NVDefault_HandleAcquireBitStream(int *pBufferSize, void *pUserData)
static void _stdcall NVDefault_HandleReleaseBitStream(int nBytesInBuffer, unsigned char *cb,void *pUserData)
这两个函数找思路，但是因为NVEncodeFrame函数封装在"NVEncoderAPI.h"，看不到具体函数调用的过程，求各位大神指点
附demo中的编码函数：

bool VideoEncoder::EncodeFrame(NVVE_EncodeFrameParams &sFrameParams, CUdeviceptr dptr_VideoFrame, CUvideoctxlock ctxLock)
{
    // If this is the first frame, we can start timing
    if (m_nFrameCount == 0)
    {
        Start();
    }

    HRESULT hr = S_OK;

    if (m_pEncoderParams->iUseDeviceMem)
    {
        // Copies video frame from system memory, and passes it as a System pointer to the API
        switch (m_pEncoderParams->iSurfaceFormat)
        {
            case UYVY: // UYVY (4:2:2)
            case YUY2:  // YUY2 (4:2:2)
                CopyUYVYorYUY2Frame(sFrameParams, dptr_VideoFrame, ctxLock);
                break;

            case YV12: // YV12 (4:2:0), Y V U
            case IYUV: // IYUV (4:2:0), Y U V
                CopyYV12orIYUVFrame(sFrameParams, dptr_VideoFrame, ctxLock);
                break;

            case NV12: // NV12 (4:2:0)
                CopyNV12Frame(sFrameParams, dptr_VideoFrame, ctxLock);
                break;

            default:
                break;
        }

        sFrameParams.picBuf = NULL;  // Must be set to NULL in order to support device memory input
        hr = NVEncodeFrame(m_pEncoder, &sFrameParams, 0, (void *)dptr_VideoFrame); //send the video (device memory) to the
    }
    else
    {
        // Copies video frame from system memory, and passes it as a System pointer to the API
        hr = NVEncodeFrame(m_pEncoder, &sFrameParams, 0, m_pSNRData);
		
    }

    if (FAILED(hr))
    {
        printf("VideoEncoder::EncodeFrame() error when encoding frame (%d)\n", m_nFrameCount);
        return false;
    }

    if (sFrameParams.bLast)
    {
        m_bLastFrame  = true;
        m_nLastFrameNumber = m_nFrameCount;
    }
    else
    {
        frameSummation(m_nFrameCount);
        m_nFrameCount++;
    }

    return true;
}
