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 descAclLiteError atlRet = CreateInputStreamDesc(frameData);if (atlRet != ACLLITE_OK) {ACLLITE_LOG_ERROR("Create stream desc failed");return atlRet;}if (!frameData->isFinished) {// create out descatlRet = 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 decoderet = 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，

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 sizeret = acldvppSetStreamDescData(streamInputDesc_, inBufferDev);ret = acldvppSetStreamDescSize(streamInputDesc_, inBufferSize);// Device memory g_picOutBufferDev is used to store output data decoded by VDECret = acldvppMalloc(&g_picOutBufferDev, dataSize);// Create output image description information, set the image description information properties// picOutputDesc_ is acldvppPicDescpicOutputDesc_ = 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 automaticallycalls callback callback function to write the decoded data to the file, and then timely releaserelevant resources */ret = aclvdecSendFrame(vdecChannelDesc_, streamInputDesc_, picOutputDesc_, nullptr, nullptr);printf("ret  =================%d\n", ret);restLen = restLen - 1;}

运行结果如下

demo报同样的错误，但是我发现如果原视频用华为的std::string filePath =  "../data/vdec_h265_1frame_rabbit_1280x720.h265"就不报错，换成我自己的几个视频就报错。

4 最终解决方法

华为技术支持让试试：samples: CANN Samples - Gitee.com

https://gitee.com/ascend/samples/tree/master/cplusplus/level1_single_api/7_dvpp/vdec_sample

 我试了下这个，发现是可以，没报错，那么需要将我的工程中的解码代码全都替换成这个sample的这些接口，需要把解码代码重写。

另外下图是这个sample对应的解码原理
