Buffer Address Verification Error Due to Buffer Allocation with an Incorrect API

Symptom

When a VPC API is called, the HI_ERR_VPC_BADADDR (0xA0078011) error code is returned, and an error message is recorded in the log. The error logs vary according to the version.

• Log example 1

  device 0, vpc address is illegal, please make sure it has been allocated with hi_mpi_dvpp_malloc or acldvppMalloc.

• Log example 2

  dvpp_check_mem_usable [Line]:85 mem:0x****f000****4020 is not usable, please check:1. mem not alloced or has been freed;2. make sure mem actual size should be:8017920

Possible Cause

According to the log information, the specified API is not used to allocate buffer.

Solution

Check the code to see whether acldvppMalloc in media data processing V1 or hi_mpi_dvpp_malloc in media data processing V2 is used to allocate buffer for storing the VPC input or output data.
