[FFmpeg-user] mp4 generate moov atom at beginning of recording

[simon mares]

Hello, is it possible to generate a pre-defined moov atom for fixed 
lenght of fe. 8 hours with use of 
http://ffmpeg.org/ffmpeg-all.html#MOV_002fMP4_002fISMV arguments? Video 
would never be seeked beyond the real duration, as I would not allow.

Reason for doing this is that I'm experimenting with something and I 
would like to playback the file that I'm still recording, so it's kind 
of a live-streaming, but it's only used locally. As I'm only transcoding 
from .ts to .mp4 file no CPU is used, this is also my goal.

Codec is h264, 720p, 25pfs. Video is generated with blackmagic pro-recorder.

Any help or tip is highly appreciable!

Simon
