[...] Do note that calculating the reduced DAR requires some mathematics which may not be simple to do from e.g. shell or simple scripting languages. This is the primary reason why I was hoping ffprobe to do this for me. Would it be acceptable to print the reduced "raw" height:width ratio as surface_aspect_ratio (or with some other better name)? The application interpreting the info can then use that instead of display_aspect_ratio when it's N/A.
Depending on the application use-case it might be sufficient to use a float DAR, i.e. when comparing to a list of values like 4:3, 16:9, etc (within some "epsilon" delta, of course).
