[FFmpeg-user] Option -brand does nothing

[Ulf Zibis]

Hi,

I used option "-brand" to manually set the major brand name, but here is what I got:

$ ~/Projects/ffmpeg/dev_2/ffmpeg -i MVI_1324.MOV -c:a copy -profile:v baseline -level 4.1 -colorspace smpte170m -color_primaries bt709 -color_trc bt709 -refs 1 -g 15 -map_metadata 0 -brand "qt  CAEP" MVI_1324_smpte170m_git.mov
