hi_mpi_vi_set_pipe_frame_dump_attr
The
The
Description
Sets the dump attributes of a physical VI pipe.
Restrictions
- This API can be called only after a VI pipe is created by calling hi_mpi_vi_create_pipe.
- To dump data in different pixel formats, you can specify the pixel format when creating a pipe by calling hi_mpi_vi_create_pipe before dumping data. The pixel format must be aligned with the actual output format of the sensor module.
- To dump cropped images, you can call hi_mpi_vi_set_pipe_pre_crop to set pipe cropping before dumping.
- To dump compressed or non-compressed images, you can specify the compression type when creating a pipe by calling hi_mpi_vi_create_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.
