API/Interface Changes

The following sections cover API and interface changes such as DriveWorks, Camera, NvStreams, NvMedia, cuPVA. The sections also cover dynamic changes, such as the programming sequence and static changes to header files.

Note

The cuPVA SDK API is backwards compatible when migrating to version 7.0, and the PVA SDK maintains source compatibility between major releases. Download the version of the PVA SDK that corresponds to your NVIDIA DriveOS™ version and rebuild your application.
