How to change SAR(DAR) in x2645 stream

[pkirill]

Hi guys

I got wrong DAR after long hours coding.
Megui put --sar 15:16 without my interaction and without any reason to do this.

There was no global MeGUI_darx(y) in the scripts.

Now i need to change this in resulting .mp4 files without recoding.

Is it possible ?
If yes, How to do this ?
Is there a commandline utility to change indly sar(dar) parameter in mp4 files.

Thanks

yes...mp4box...demux the .mp4 to raw and remux again with the desired dar (par)...
