how to merge mp4 and m4a files (ffmpeg method)

[minibattleship]

Thank you works very well. Note to Windows users: add "video.mp4" and "audio.m4a" files to the "bin" folder in program root folder before merging because with this command line default work folder is set to bin ("output.mp4" also goes there).

Worked like a charm!! Thanks for teaching me about how to use ffmpeg a little :)

I created a batch file in a specific folder. Input and output all work fine.
Thanks!

hey, one question; does ffmpeg only mux it or do they completely become one file?

Hi. I'm on windows 7 it says no such file or directory. Please help! Thanks!

Serious question: how will ffmpeg even KNOW which video and which audio I want to merge?

Thanks for the tip, Man! This works 1000 times faster than the "free for a while" JFuse Movie Joiner :-)

Hi, I'm using Ubuntu 14.04, and i input: "ffmpeg -i 1 -i 2 -acodec copy -vcodec copy output.mp4", but the output file is identical tothe first file. Please help! :)

Looks like it's working for me, but the output file is just the same as the video file without the sound merged in.
