VideoLabeler could not read file; Unable to initialize video properties

Hi - I am trying to use videoLabeler, but I am unable to read the file due to the following error:

Error using groundTruthDataSource/parseAndPopulateInputs
Could not read file due to an unexpected error. Reason: Unable to initialize
the video properties

Error in groundTruthDataSource (line 194)

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:

Hope it helps!
