hi i am developing an application with wowza that records a audio/video conversation with multiple persons,

so wowza generates a mp4 file for each person that is sharing your microphone/camera

Until here is everything right, my doubt is how to play all this media in a synchronized way.

Example:

Person 1 starts to share his audio/video on time 00:05s.

Person 2 starts to share his audio/video on time 00:10s.

Those 2 persons keeping talking during 1 minute.

i would like to merge this files in a single file, i tried to use ffmpeg but i kind give up.

Someone with experience in this kind of application can suggest some tools or way to implement this?

thanks

You might be able to do it with VLC:

You might have syncing issues, but if the videos are exactly the same encoding and start at the same time, it might work.
