环境

• CANN：8.0RC1
• SDK：6.0RC1
• 设备：Atlas 300I Pro

流程

• 调用昇腾版本ffmpeg接口：av_hwdevice_ctx_create构造deviceCtx并初始化解码器

• 解码视频流得到AVFrame

• 使用AVFrame的数据构造MxBase::Image

• 将Image转为Tensor时报错并死亡

  //部分代码
  
  // 1.初始化deviceCtx
  AVBufferRef* hwCtx = nullptr;
  int err = av_hwdevice_ctx_create(&hwCtx, AV_HWDEVICE_TYPE_ASCEND, deviceId.c_str(), NULL, 0);
  
  // 2.使用ffmpeg解码得到AVFrame
  
  // 3.构造Image并转为Tensor
  size_t size = src->linesize[0] * h + src->linesize[1] * (h * 0.5);
  std::shared_ptr<uint8_t> data(src->data[0]);
  MxBase::Image image(data, size, acl::deviceId, MxBase::Size(w, h));
  MxBase::Tensor tensor(std::vector<uint32_t>{(uint32_t)h, (uint32_t)w, 3}, MxBase::TensorDType::UINT8, acl::deviceId);
  tensor = image.ConvertToTensor();

• 运行到最后一行时出现如下报错
