If if reproduce the video Clean.mp4 with the subtitles file Clean.ass in the same directory, the subtitles areshown correctly.
Instead if I try to add the ass file to the mp4 container the subtitle are no more shown correctly.
The ffmpeg command I used is:
ffmpeg.exe -i Clean.mp4 -i Clean.itIT.ass -c copy -c:s mov_text add_sub.mp4
I have ffmpeg with this settings: --enable-fontconfig.
Constraints
- Cannot change video container, I need an mp4 file (no mkv)
- Cannot impress the subtitles (no hardsub)
- Have a single file with video, audio and subtitle in it.
Is it possible to have the requested result with thiese constraints?
