  • replace a word in subtitle with ffmpeg

    19 mars 2020, par wotanii

    I want to use ffmpeg to replace all occurrences of a word in all subtitles of a video file with ffmpeg. All non-subtitles channels should be copied (not reencoded) and all formatting from the original subtitles should stay if possible.

    example :

    ffmpeg -i input.mkv -SUBTITLEFILER='old_word/new_word' output.mkv

    I am using ubuntu 19.04 and bash (in case additional steps or dependencies would be required for this)

  • avcodec/dca_parser : Extend DTS core sync word and fix existing check

    avcodec/dca_parser : Extend DTS core sync word and fix existing check

    Check extended sync word for 16-bit LE and BE core streams to reduce
    
probability of alias sync detection. Previously sync word extension was
    
checked only for 14-bit streams (and this check did not properly work
    
across buffer boundary).
    

    Use 64-bit parser state to make extended sync word detection work across
    
buffer boundary.
    

    This is sufficient to make the sample in ticket #4492 parse
    
successfully.
