[FFmpeg-user] How to embed subtitles to .mp4 movie using ffmpeg

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
*http://stackoverflow.com/questions/8672809/use-ffmpeg-to-add-text-subtitles
<http://stackoverflow.com/questions/8672809/use-ffmpeg-to-add-text-subtitles>*.


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*

*This error doesn't happen when using*
*ffmpeg -i in.mp4 -f srt -i subs.srt -c:v copy -c:a copy -c:s mov_text
out.mp4, *but still there are no subtitles.
