[FFmpeg-user] Closed Caption Stream

Hello everyone!!!

I'm doing some R&D about using ffmpeg in a transcoding script, and I got
stuck in a serious problem.

I must, let's say, transcode a video that has CEA708 Closed Caption embed
on it, I tried to search the Web for some info on how to deal with it using
ffmpeg, since it complains about the stream that contains about it's data...

    Stream #0:9: Data: none
      file_package_name: Source Package
      data_type       : vbi_vanc_smpte_436M
Data stream encoding not supported yet (only streamcopy)

I  tried to do -map 0:9 with -c:d copy and it just corrupts the file

Any thoughts 'bout how to solve it?

Thanks and regards!
