Video-specific ProcessorContext for graph execution. More...
| Header: | #include <VideoContext> |
| Since: | 1.0 |
| Inherits: | media::graph::ProcessorContext |
Provides video frame data and metadata to graph processors during execution. Wraps a QVideoFrame with sample access that conforms to the media::graph::ProcessorContext interface.
The "samples" in video context are pixels: sourceSamples() returns the input frame data and destinationSamples() returns the output frame data. sampleCount() returns the total number of bytes.
