TX2 video compress performance more weaker than TX1, why ?

I have test video compress performance of TX1 and TX2, but result show TX2 more weaker than TX1

first TX1

gst-launch-1.0 nvcamerasrc num-buffers=1800 ! 'video/x-raw(memory:NVMM), format=(string)I420, width=(int)4096, height=(int)3076, framerate=(fraction)30/1' ! nvvidconv !

it take 1 min

Hi, can you try with 2592 x 1944? The max resolution of onboard 5693 is 2592x1944, not 4K.

but i use videotestsrc on TX2 also take 1 min 42s

i use TX2 module on board of TX1, is it will influence performance of TX2 ?

Hi gunagjie,
videotestsrc is a CPU-buffer source. The best performance needs NVMM-buffer source like nvcamerasrc.

i test nvcamerasrc can supply 4k@30fps video raw data

Available sensor modes show you are using onboard ov5693, which does not have 4K…

how can i test 4K@30fps performance ?

hello gunagjie,

you could contact NV partners for 4k@30 bayer sensors.
