Comment (by Marth64):

 It is not possible in this way.
 Closed Caption bytes are embedded into the video stream's SEI bytes or
 user data, so a stream copy will not achieve a presentable result (also I
 do not believe MP4 can house a discrete EIA608 stream, not that it would
 be useful). Likely this will have to be a BSF filter.
