Matroska cropping question

[shambles]

I know it's possible to set crop parameters for a video track in the container, but would it be possible to toggle the cropping on or off during playback or somehow else have a cropped and an uncropped version without having to double the filesize or to remux the file prior to playback?

Sorry for asking this here shambles, but how do you set crop parameters in Matroska?

In mkvmerge it's: --cropping <TID:left,top,right,bottom>

Thx :)

EDIT: it seems the cropping values are written into the file, but with various splitters and decoders the video doesn't get cropped at all :confused:
