I have a usecase where i have the output of the decoder ( avdec_h264) I420
converted to RGB,RGBA,BGR & BGRA respectively.

using a 1920x1080 video

 gst-top-1.0 gst-launch-1.0 filesrc location=<FILE-NAME.mp4>
num-buffers=3500 ! decodebin ! videoconvert ! video/x-raw,format=BGRA !
videoconvert ! fpsdisplaysink

>From I420 TO  BGRA : 4.2 ms
                        RGBA :  10.4 ms
                        RGB : 13.1 ms
                        BGR: 13.6 ms 

Is the timings normal  here?
It would great if someone could give bit more insight towards the
videoconversion in gstreamer.
