Sorry description and logs are wrong :P

Pipeline is:

GST_DEBUG=ffmpegcolorspace:4 gst-launch -v videotestsrc num-buffers=1 !
"video/x-raw-yuv" ! ffmpegcolorspace !
"video/x-raw-rgb,bpp=(int)32,depth=(int)24,endianness=(int)4321,width=(int)320,height=(int)240,framerate=(fraction)30/1,red_mask=(int)65280,green_mask=(int)16711680,blue_mask=(int)-16777216;video/x-raw-rgb,bpp=(int)32,depth=(int)32,endianness=(int)4321,width=(int)320,height=(int)240,framerate=(fraction)30/1,red_mask=(int)65280,green_mask=(int)16711680,blue_mask=(int)-16777216,alpha_mask=(int)255"

and in the logs:
