How to add subtitles to a mp4 file permanently?
 
Hi,
How do you add subtitles to video file permanently in Linux?

Try this.
Code:
ffmpeg -i inputfile.mp4 -vcodec copy -acodec copy -i input_subfile.srt -scodec mov_text -map 0:0 -map 0:1 -map 1:0 -y outfile.mp4

I've use handbrake and bake them into the file, but that requires re sampling them.

Wrote something up a while back about using MKV's for this, and how to extract subtitles etc.

I used this command. It worked fine except it didn't save the background behind the text..

Code:
ffmpeg -i infile.mp4 -vf subtitles=subtitles.srt outfile.mp4

Try downloading the static build of ffmpeg from their download site.

Note, though, that mov_text seems to be a hit-and-miss situation; sometimes it works, sometimes it doesn't. You might have much better results re-muxing into a matroska container (.mkv), and play it using VLC.
