Restrictions
- This API must be called after a pipe is created by calling hi_mpi_vi_create_pipe and before hi_mpi_vi_start_pipe is called.
- The VC 1 and VC 2 are output by some sensors in the 2-to-1 WDR scenario. If the VC IDs are not specified separately by calling this API, the VC IDs do not match the default VC 0 and 1 in the system. As a result, data fails to be obtained.
- Virtual pipes are not supported.
