Comment (by navilor):

 Thank you very much for providing me information on the -a53cc option. It
 is working as expected. What baffles me entirely is that the -ac option
 removes EIA-608 captions when I do not use decimate. I have been using
 that option for years.

 Will the mpeg2_metadata_bsf option work with both MPEG Video Version 2 and
 H.264 content in an MPEG-TS container, specifically the m2ts container? I
 ask because I am hoping that it will be a codec neutral option.
