Restrictions
- After enabling an HDMI by calling hi_mpi_hdmi_open and before starting the HDMI by calling hi_mpi_hdmi_start, call this API to set the HDMI attributes. Ensure that the value of hi_hdmi_id in hi_mpi_hdmi_open is the same as that in this API.
If you have started the HDMI by calling hi_mpi_hdmi_start, you need to stop the HDMI by calling hi_mpi_hdmi_stop, set the attributes, and then restart the HDMI. The behavior that does not comply with this process is undefined and is not supported currently.
- If only some attributes need to be set, obtain the attributes by calling hi_mpi_hdmi_get_attr, assign values to these attributes, and then set them.
- Currently, this API does not support multiple processes.
