Description

  • row_iter() for Frame: it would return a &[&[Pixel]], chroma slices can appear two times if the subsampling.
  • tile_iter() for Frame: would provide a lightweight version of our current tiles machinery, decoupled from the encoder settings.

Contributor guide

Research direction
Implement the row iter() method that returns a slice of pixel rows, handling chroma subsampling by repeating chroma slices. Implement tile iter() to provide a lightweight tile iterator decoupled from encoder settings.
