Hi There,
I run the same gst-launch-1.0 ximagesrc command in different platform， it work well in jetson tx2, but when I run in jetson nx, I got the following error:

The resolution ratio is 1280*720, and I want to cut it to 1233x688, please kindly suggest. Thanks!

Hi,
Please check if it works in 1280x720. If 1280x720 works, you can then downscale to 1234x688 through nvvidconv plugin. Odd width 1233 may not work properly. The command is like:

$ gst-launch-1.0 ximagesrc use-damage=0 ! video/x-raw ! nvvidconv ! 'video/x-raw(memory:NVMM),format=NV12,width=1280,height=720' ! nvvidconv ! 'video/x-raw(memory:NVMM),format=NV12,width=1234,height=688' ! ...

Hi，
Yes, it works in 1280x720, and I want to crop the image, nvvidconv plugin just scale the image, I already tried nvvidconv plugin parameter (bottom, top, left, right), but it dosen’t work
