hi_mpi_vo_enable

The Atlas 200/300/500 Inference Product does not support this API.

The Atlas Training Series Product does not support this API.

Enables a VO device to use the VO function.

Configure the public attributes of a VO device before calling this API. Otherwise, an error is returned, indicating that the VO device is not configured.
If the device is enabled, calling this API returns an error indicating that the device is not disabled. The device cannot be enabled repeatedly.
To ensure smooth switching between the startup screen and the operation GUI, check whether the VO hardware is enabled. If yes, a success message is returned, and the existing API and timing configuration are used.
To change the VO API or timing configuration, call hi_mpi_vo_disable to forcibly disable the VO hardware and then enable it.
Currently, this API does not support multiple processes.
