Video Processing

Video processing functions (VPP) take raw frames as input and provide raw frames as output.

The actual conversion process is a chain operation with many single-function filters.

Video processing operation pipeline

The application specifies the input and output format; oneVPL configures the pipeline according to the specified input and output formats. The application can also attach one or more hint structures to configure individual filters or turn them on and off. Unless specifically instructed, oneVPL builds the pipeline in a way that best utilizes hardware acceleration or generates the best video processing quality.

The Video Processing Features table shows oneVPL video processing features. The application can configure supported video processing features through the video processing I/O parameters. The application can also configure optional features through hints. See Video Processing Procedures for more details on how to configure optional filters.
