How to add a MOOV atom in a mp4 video file

Question

I am working on live device to server streaming in android. I am able to send data in bytes on server but when i play that file during recording on server VLC

Answer 1

the mp4 format needs the moov atom information to play the video, and to generate the moov atom the video must be finished, you can't play a mp4 file while it is recording because you still don't have all the information to create the moov atom part.

What you want to do is some kind of real-time-streaming (play while is recroding) so you need to use another formats. HLS streaming and mpeg-dash stores the video in tiny chunks (2seconds to 10seconds) and send to the users, this way the users plays many finished files one after the other.

as @Sebastian Annies suggested, to create many tiny mp4 files and concatenate is the same approach: to have tiny finished files and play as a list, here you could get more information What exactly is Fragmented mp4(fMP4)? How is it different from normal mp4?
