  1. My head is bloody from several days of working on this. I could not find any previous posts, so here is my problem.

    I think I have the latest version of ffmpeg running on Windows 7. I have tried multiple subtitle file formats (srt, ssa, stl) and each of the scodecs that support encryption (xsub, dvdsub). They all have the same issue; output pasted below.

    C:\Users\Bill\Videos\testdir>ffmpeg -i here.mp4 -i here.srt -y -sameq -scodec xsub -acodec copy -vcodec copy there.mp4 -newsubtitle

    I would be grateful for any assistance.

    Thanks.

  2. Are you trying to mux in soft subs ?

    Another approach would be to use mp4box (yamb is a GUI for it)

  3. Yes, soft subs or hard subs would work for me. I spent some time working with Yamb, but it seemed complex to set up. Is it worthwhile to invest the time to get it working? I would prefer a command line application that I can write bat files to execute.

    Thanks.

  4. mp4box is a command line utility . You should be able to set up .bat files
    http://gpac.sourceforge.net/doc_mp4box.php

    hard subs would require re-encoding . This means quality loss, takes much longer, but it would be more compatible (some players do not have proper splitters for subs in mp4 container; also mp4 container only supports text based subs e.g. srt) . If you wanted to hardsub you could use batch avisynt / ffmpeg scripts
