Description
Push-mode source Node.
The application feeds samples via Run::push().
Add this Node when the application owns frame production. Because it carries InputRole::Push, the Graph must be driven through Graph::build() plus Run::push() per sample (not Run::run(), which is for source-role pipelines).
