Thank you Marcelo great job congratulations.
The statement you send me work pretty good.
Preserve my close caption using this instruction.
Let me ask you a question.
What software do you use to put closed captions inside the video when the videos are .mpg, no embedded . I need to turn on / off closed caption.
FFmpeg only work with subtitles embedded, but no really with closed caption.
Exist any command line software to do that?
Thank you again.

Ahh, nothing like actually trying the command. The "a53cc" option has to be
used outside the internal parameters of x264.
ffmpeg -i INPUT.mpg -c:v libx264 -x264opts keyint=123:min-keyint=20 -a53cc
1 -an -f mpegts OUTPUT.ts
Here is a (working and tested) command line version, and the full command
output:
C:\>ffmpeg -i cea708_dtv.mpg -c:v libx264 -x264opts keyint=60:min-keyint=30
-a53cc 1 -an -f mpegts OUTPUT.TS
