This is good, this could indicate progress !
Maybe next time before u have ur temper tantrum, u can put the bottle aside, and read posts properly. Zorr did directly mention weights to u in regards to ffmpeg's implementation but u seem to have chosen to ignore that... until u remembered.
well, to quote u: what gives ?

@VS_Fan and Poisondeathray. Thanks. Alot to think about there.
