  • How to embed subtitles to .mp4 movie using ffmpeg

    25 novembre 2016, par hudac

    I’m trying to embed subtitles I wrote to a movie I created.
    I’m using FFmpeg version : ffmpeg-20150418-git-edbb9b5-win64-static with the command :
    ffmpeg -i in.mp4 -f srt -i subs.srt -c:v copy -c:a copy -c:s mov_text out.mp4 I saw here.

    But I get errors during the process, and when the process is done there’s an output file out.mp4 without subtitles embedded.
    When I play the in.mp4 in some player such as media player classic with the subtitles separately, the subtitles are sync and everything is fine.

    The subtitles are subrip encoded in UTF8.

    I tried to look out for these errors but didn’t find anything useful. it seems something ridiculous.
    What am I doing wrong ?

    Errors such as :

    [mp4 @ 00000000003fe020] Codec for stream 0 does not use global headers but container format requires global headers
    [mp4 @ 00000000003fe020] Codec for stream 1 does not use global headers but container format requires global headers
