1 [ERROR] Send frame to vdec failed, errorno:507018

某项目中的代码运行报错 [ERROR] Send frame to vdec failed, errorno:507018

    AclLiteError VdecHelper::Process(shared_ptr<FrameData> frameData, void* userData) {
        // create input desc
        AclLiteError atlRet = CreateInputStreamDesc(frameData);
        if (atlRet != ACLLITE_OK) {
            ACLLITE_LOG_ERROR("Create stream desc failed");
            return atlRet;
        }

        if (!frameData->isFinished) {
            // create out desc
            atlRet = CreateOutputPicDesc(outputPicSize_.load());
            if (atlRet != ACLLITE_OK) {
                ACLLITE_LOG_ERROR("Create pic desc failed");
                return atlRet;
            }
        }
        else {
            outputPicDesc_ = acldvppCreatePicDesc();
            if (outputPicDesc_ == nullptr) {
                ACLLITE_LOG_ERROR("Create vdec output pic desc failed");
                return ACLLITE_ERROR_CREATE_PIC_DESC;
            }
        }

        // send data to dvpp vdec to decode
        ret = aclvdecSendFrame(vdecChannelDesc_, inputStreamDesc_,
            outputPicDesc_, nullptr, userData);
        if (ret != ACL_SUCCESS) {
            ACLLITE_LOG_ERROR("Send frame to vdec failed, errorno:%d", ret);
            return ACLLITE_ERROR_VDEC_SEND_FRAME;
        }

        return ACLLITE_OK;
    }

    void VdecHelper::SetOutputPicSize(uint32_t picSize) {
        if (picSize < outputPicSize_.load()) {
            outputPicSize_.store(picSize);
        }
    }

用vscode调试发现

发现正常和报错时的一些变量也没什么区别，

2 bug解决尝试1

然后网上搜507018的错误码，找到如下链接昇腾社区-官网丨昇腾万里让智能无所不及

这上面就是说每次都要重新配置描述类型，但是我看了下我的代码里面已经是每次都重新配置描述类型了，该方法行不通。

3 bug解决尝试2

不知道怎么做了，去下载华为官方的sample，然后先跑demo试试，去下载samples: CANN Samples - Gitee.com

https://gitee.com/ascend/samples/tree/master/cplusplus/level2_simple_inference/0_data_process

然后编译运行这个samples-master/cplusplus/level2_simple_inference/0_data_process/vdec

在代码中增加这一行打印

    while (restLen > 0) {
        //INFO_LOG("------------------------- ");
        // inBufferDev means the memory for input video data by Device, and inBufferSize means the memory size
        ret = acldvppSetStreamDescData(streamInputDesc_, inBufferDev);
        ret = acldvppSetStreamDescSize(streamInputDesc_, inBufferSize);

        // Device memory g_picOutBufferDev is used to store output data decoded by VDEC
        ret = acldvppMalloc(&g_picOutBufferDev, dataSize);

        // Create output image description information, set the image description information properties
        // picOutputDesc_ is acldvppPicDesc
        picOutputDesc_ = acldvppCreatePicDesc();
        ret = acldvppSetPicDescData(picOutputDesc_, g_picOutBufferDev);
        ret = acldvppSetPicDescSize(picOutputDesc_, dataSize);
        ret = acldvppSetPicDescFormat(picOutputDesc_, static_cast<acldvppPixelFormat>(format_));

        /* Perform video stream decoding. After decoding each frame of data, the system automatically
         calls callback callback function to write the decoded data to the file, and then timely release
         relevant resources */
        ret = aclvdecSendFrame(vdecChannelDesc_, streamInputDesc_, picOutputDesc_, nullptr, nullptr);
        printf("ret  =================%d\n", ret);
        restLen = restLen - 1;
    }

运行结果如下
