 Dear ffmpeg team

 isom cannot be a MAJOR BRAND in MP4, please could you apply a fix to
 correctly record this by default as:

 <FileTypeBox MajorBrand="mp42" MinorVersion="0">

 'isom' cannot be used as a major brand, it is currently prohibited by
 ISO/IEC 14496-12 sec 6.3 paragraph 2.

 This is causing problems down the line!
