Emerge video and audio and subtitle together

[CrymanChen]

Hi guys,
I'm meeting a problem of using ffmpeg to emerge different videos and audios and subtitles together so I came here to find some answers.

Here's what I've got:
1 Video: v_dec.mp4
2 Audios: a_eng.mp4 & a_zho.mp4
2 Subtitles: CHI.srt & ENG.srt
and how to put them together in a new mp4 file using ffmpeg?

Thank you in advance.

Below is the code that I tried typing in, and I'm wondering what would be the reason of the failure:

ffmpeg -i v_dec.mp4 -i a_eng.mp4 -i a_zho.mp4 -i CHI.srt -i ENG.srt -map 0:v:0 -map 1:a -map 2:a -map 3:s -map 4:s final_new.mp4

Any suggestion or advice is highly appreciated.

P.S. I tried emerging video and audios——without the subtitle part, and it worked.

ffmpeg -i v_dec.mp4 -i a_eng.mp4 -i a_zho.mp4 -map 0:v:0 -map 1:a -map 2:a final.mp4

But I don't really know how to deal with the subtitle stuff.

Use clever Ffmpeg-GUI.
Load the video file, click main, click multiplex, click add stream, add your audio and subtitle files, select all streams on the left side, select the container you want (mp4 or mkv), click multiplex.
Done.

It is so nice of you. Thank you for your advice, it worked.
