[FFmpeg-user] Setting color is strange showvolume filter

[nicolab]

Setting color RGB(0xffffff), Green is fine, but Red, Blue is reversed?

example
ffplay -f lavfi aevalsrc="sin(440*2*PI*t):s=8000,showvolume=c=0x00ff00"
color is 0x00ff00

ffplay -f lavfi aevalsrc="sin(440*2*PI*t):s=8000,showvolume=c=0xff0000"
color is 0x0000ff, not 0xff0000
