[FFmpeg-user] shuffleplanes

[Michael Koch]

Hello,

I have a question about the shuffleplanes filter. In this example the 
pixel format is RGB24. So the first plane is red and the second plane is 
green. I want to swap the red and green planes.

ffmpeg -f lavfi -i testsrc2 -lavfi 
format=rgb24,split[a][b];[b]shuffleplanes=1:0:2[b];[a][b]vstack -frames 
1 -y out.png

But in the output green is swapped with blue. I don't understand why.
I'm using the latest Windows build, just a few days old.
