hi_mpi_vi_send_pipe_yuv

Description

Sends YUV data through a VI pipe.

Restrictions

• Call hi_mpi_vi_start_pipe to start the pipe before calling this API.
• Before sending YUV data, set the data source of the pipe to HI_VI_PIPE_FRAME_SOURCE_USER by calling hi_mpi_vi_set_pipe_frame_source. In this case, the data from the sensor is not sent to the ISP BE for processing, and the ISP BE processes only the frame data sent by the user.
• When YUV data is sent by calling this API, the YUV data must meet the following requirements:
  • The width and height of the YUV data must be the same as those specified when a pipe is created by calling hi_mpi_vi_create_pipe.
  • The YUV frame information that is sent must be authentic and valid, which is obtained by calling hi_mpi_vi_pipe_get_buffer.
  • The pixel format of the YUV data must be the same as that configured when a pipe is created by calling hi_mpi_vi_create_pipe.
  • field of the YUV data must be set to HI_VIDEO_FIELD_FRAME.
  • video_format of the YUV data must be set to HI_VIDEO_FORMAT_LINEAR.
  • compress_mode of the YUV data must be HI_COMPRESS_MODE_NONE.
  • dynamic_range of the YUV data must be HI_DYNAMIC_RANGE_SDR8, HI_DYNAMIC_RANGE_SDR10, or HI_DYNAMIC_RANGE_XDR.
• This API cannot be called in WDR mode.
• Data can be sent only from the BE, not from the FE.
