      • extractClosedCaptions

        Blob extractClosedCaptions​(Blob video,
                           String outputFormat,
                           String startAt,

        Extracts the closed captions from a video blob.
        Parameters:
        video - the input blob
        outputFormat - the outformat of the captions (srt, txt, ttxt is the default)
        startAt - the start time in format "xx:xx"
        endAt - the end time in format "xx:xx"
        Returns:
        the closed captions if any were found
