appsink is slow

[aircheese]

Hi all. I'm newbie here.

I'm using fallowing pipelines. (with TX1 and IMX274 Camera)

Pipeline 1) 3840x2160, YUV, No Converting,  60 FPS(can get images)
nvcamerasrc sensor-id=0 ! video/x-raw(memory:NVMM), width=(int)3840,
height=(int)2160, format=(string)I420, framerate=(fraction)60/1 ! nvtee !
nvvidconv flip-method=0 ! video/x-raw, format=(string)I420 ! appsink

Pipeline 2) 3840x2160, RGB, Converting, 18 FPS (can get images)
nvcamerasrc  sensor-id=0 ! video/x-raw(memory:NVMM), width=(int)3840,
height=(int)2160,format=(string)I420, framerate=(fraction)60/1 ! nvtee !
nvvidconv flip-method=2 ! video/x-raw, format=(string)BGRx ! videoconvert !
video/x-raw, format=(string)BGR ! appsink

Pipeline 3) 3840x2160, RGB, Converting, 60 FPS (Just Displaying, can't get
images)
nvcamerasrc fpsRange=\"60.0 60.0\" sensor-id=0 ! video/x-raw(memory:NVMM),
width=(int)3840, height=(int)2160, format=(string)I420,
framerate=(fraction)60/1 ! nvtee ! nvvidconv flip-method=0 !
video/x-raw(memory:NVMM), format=(string)I420 ! nvoverlaysink sync=false
name=mysink

I need to get camera images with 3840x2160, RGB, 60FPS. But,  I can't get
images with 60 fps.
When I use "Pipeline 3", I can see camera images with 60fps, however, it's
not possible to get raw data. just possible to display. I think the problem
is sink.(appsink, nvoverlaysink) 

Could you please anybody help me?

thank you for reading.
Have a nice day everyone.

Regards,
Claude
