Dump attributes of a physical VI pipe.

Before calling this API, you must call the hi_mpi_vi_create_pipe API to create a pipe.

To dump data in different pixel formats, you can call the hi_mpi_vi_create_pipe API to specify the pixel format when creating a pipe before dumping. The pixel format must be aligned with the actual output format of the sensor module.
To dump the cropped image, you can call the hi_mpi_vi_set_pipe_pre_crop API to set the pipe cropping before dumping.
To dump compressed or non-compressed images, you can call the hi_mpi_vi_create_pipe API to specify the compression type when creating a pipe before dumping.
Virtual pipes are not supported.
If the current API is called after the pipe is started by calling hi_mpi_vi_start_pipe, the images that are not fetched by calling hi_mpi_vi_get_pipe_frame in the internal buffer are cleared.
