- Description:
This module contains the implementation of PPM->YUV conversion. It is a wrapper class for calling FFMPEG. FFMPEG will perform the conversion considering the aspects of the LF, such as width, height, number of views, encoding order. Also, more importantly, it will deal with the colour conversion.

Generate a list of views for FFMPEG conversion.
- Parameters:
n_views_width (int) – Number of views in width
n_views_height (int) – Number of views in height
initial_width (int) – Initial width offset
initial_height (int) – Initial height offset
step_width (int) – Step size in width
step_height (int) – Step size in height
views_path (Union[str, Path]) – Path to the views
scan_order (ScanFunctionType) – Function defining the scan order
- Returns:
List string for FFMPEG
- Return type:
str
