#7055: Using decimate allows EIA-608 captions to pass through to MP4 files even when the -sn option is used -------------------------------------+------------------------------------- Reporter: navilor | Owner: Type: defect | Status: new Priority: normal | Component: Version: unspecified | undetermined Keywords: decimate cc | Resolution: Blocking: | Blocked By: Analyzed by developer: 0 | Reproduced by developer: 0 -------------------------------------+-------------------------------------
Comment (by tmm1): I'm not sure why decimate changes behavior, but caption data is embedded in mpeg2 user data and is not considered a subtitle by ffmpeg. You can control whether or not the libx264 encoder includes the caption data in the output video using the -a53cc option. There is also a patch on the list I submitted a couple days ago for a mpeg2_metadata_bsf option to remove a53 data from the mpeg2 bitstream. -- Ticket URL: <https://trac.ffmpeg.org/ticket/7055#comment:10> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker _______________________________________________ FFmpeg-trac mailing list FFmpeg-trac@avcodec.org http://ffmpeg.org/mailman/listinfo/ffmpeg-trac
