[FFmpeg-user] Change container/encoder used to create a file without re-encoding

Hello Carl, sorry for the error, i'm new on this encoding things and surely
i made a mistake.

What I'm trying is to get several videos that were remuxed, to it's
original state, with the same original metadata/headers. But i only have
one of those videos in original were i can get the original metadata/header
information.

The format profile of the original video is "Base Media / Version 2" and
the format profile of the remuxed ones is "Base Media". I saw that i can
remuxed them again and get "Base Media / Version 2" passing the switch
"-brand mp42". But i'm still have other metadata difference.

To make the question simple what i want to do is
1) Remove the metadata "Writing application" that is being added when using
FFMPEG.
2) Add the metadata fields "Tagged date", "TIM", "TSC" and "TSZ". I tried
for example with
-metadata -tsc="1001"
and
-metadata -TSC=1001"
but it doesn't seem to work.

3) When using ffmpeg i see on the video stream that a "GOP" format setting
is added, not sure if i can be disabled.

By the way i'm gathering the video information with MediaInfo.

Thanks in advace
