Gstreamer-1.0 video crop

I have question regarding nvvidconv, which is similar to your answer to https://devtalk.nvidia.com/default/topic/999178/jetson-tx1/cropping-image-using-nvvidconv/

I am trying to run the following command for saving a video stream from an IMX290 sensors having fish-eye lens attached to it (cropping is necessary to cut out black pixels on the sides:

$ sudo gst-launch-1.0 -v nvcamerasrc sensor-id=0 ! ‘video/x-raw(memory:NVMM),width=1948, height=1096, framerate=60/1, format=NV12’ ! nvvidconv top=0 bottom=0 left=100 right=100 ! ‘video/x-raw(memory:NVMM), width=1748, height=1096, format=I420’ ! omxh265enc control-rate=2 bitrate=16000000 ! ‘video/x-h265, stream-format=(string)byte-stream’ ! h265parse ! matroskamux ! filesink sync=true location=/home/nvidia/Documents/Stream0.mp4

This returns the following error message:

ERROR: from element /GstPipeline:pipeline0/GstNvCameraSrc:nvcamerasrc0: Internal data flow error.
Additional debug info:
gstbasesrc.c(2948): gst_base_src_loop (): /GstPipeline:pipeline0/GstNvCameraSrc:nvcamerasrc0:

/GstPipeline:pipeline0/GstFileSink:filesink0.GstPad:sink: caps = video/x-matroska

Why does this not work?

Does nvvidvonc only accept parameters that yield a cropped video having a standard display resolution format (1920x1080, 640x480,…etc.)? Does the aspect-ratio have to be kept?

If you could provide me a command for cutting approximately 100-100 left pixels on the left and right I would be delighted. No problem if you have to cut a little from top-bottom.

The information displayed with gst-inspect is a bit confusing. These properties are not the number of pixels to be cropped, but rather the starting and ending coordinates in the original image.

So you may try instead:

gst-launch-1.0 -v nvcamerasrc ! 'video/x-raw(memory:NVMM),width=1948, height=1096, framerate=60/1, format=NV12' ! nvvidconv top=0 bottom=1096 left=100 right=1848 ! 'video/x-raw(memory:NVMM),width=1748, height=1096, framerate=60/1, format=NV12' ! omxh265enc ...

Thank you for your help.
