Hi,
I understand that you faced an issue while using the “videoLabeler” function in MATLAB. This may occur if MATLAB cannot access the appropriate codec properties.
I advise you to follow the instructions provided in the ensuing documentation:
https://in.mathworks.com/help/matlab/import_export/supported-video-file-formats.html?lang=en#mw_4b3385ce-096d-4d3d-9c68-e95fd4d5dc0a
Hope it helps!
