Streaming#
Combining the buffer and synchronization functions from the previous chapters allows you to develop applications that stream sequences of data from one rendering component to another, building an efficient processing pipeline. For developers who wish to have complete control over the process, no additional functionality is required.
However, use cases for streaming can become quite complex, making the details difficult to manage. This is particularly true when portions of the pipeline are provided by independent developers who must coordinate the stream management. NVIDIA therefore provides an additional NvSciStream library layered on NvSciBuf and NvSciSync with utilities for constructing streaming application suites. For additional information, see NvSciStream APIs in the NVIDIA DriveOS API Reference.
