Only the mpeg2 and h264 decoders provide these. Default is 0 (off). This is one of the options for the x264 encoder, which has to be used with the "-x264opts" parameter. According to the above description, this filters is meant for source MPG-2 or H.264 content which already have A/53 Closed Captions embedded, and it will pass them on to the destination x264 file. Here is an example: ffmpeg -i INPUT.mpg -c:v libx264 -x264opts keyint=123:min-keyint=20:a53cc=1 -an -f mpegts OUTPUT.ts I haven't tried this command myself, but AFAIK this is the only support FFmpeg currently has for Closed Captions. _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe". _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".
