Comment (by cehoyos):
Your posts are a little confusing, please try to clarify a few things:
You write that you want us to change major_brand and minor_version in
libavformat/movenc.c (that is correct, isn't it?) which is of course
trivial. But I suspect this would not fix your actual problem which is -
if I understand correctly - playback with some player: When you write "if
I change the brand via MP4Box", please understand that MP4Box does not
just change the brand but it actually writes a new, different file with
(many) different properties, not just the brand.
So please either use a binary editor to change the values in the file
produced by FFmpeg (and test) or simply change 0x200 in the line {{{int
minor = 0x200;}}} in libavformat/movenc.c to 0 and test. If this really
fixes your issue, please clarify this here and it will get fixed quickly.
If - as I expect - this is not sufficient, please explain how we can
reproduce your (actual!) issue: Which player refuses FFmpeg's files?
