Hi, I’m trying to compile gst-nvarguscamerasrc from source because I need to modify the hard-coded gain and exposure time ranges. I cloned the code from [https://nv-tegra.nvidia.com/r/tegra/gst-src/gst-nvarguscamera.git](https://nv-tegra.nvidia.com/r/tegra/gst-src/gst-nvarguscamera.git) and checkouted tag **jetson\_35.3.1**. To make sure that this build process works, I first ran `make` and built a new `libgstnvarguscamerasrc.so` without changing any code. Then I proceeded to put this new .so file at `/usr/lib/aarch64-linux-gnu/gstreamer-1.0/libgstnvarguscamerasrc.so`. My Jetson Linux version is R35.3.1. I ran the following command to capture and save a test image: `gst-launch-1.0 nvarguscamerasrc sensor-id=0 num-buffers=1 ! "video/x-raw(memory:NVMM), format=(string)NV12, width=(int)3840, height=(int)2160" ! nvvidconv ! pngenc ! filesink location=test1.png` Then I encountered this error: ![image](https://global.discourse-cdn.com/nvidia/original/4X/c/5/e/c5efa0e7443be43b7d99e7402d67c50ad3e45fee.jpeg) This command worked before I replaced the `libgstnvarguscamerasrc.so` I noticed that the md5sum of the original libgstnvarguscamerasrc.so is identical to the one shipped in `Linux_for_Tegra/nv_tegra/nv_sample_apps/nvgstapps.tbz2` after nvgstapps.tbz2 is untarred by `apply_binaries.sh`. Note: this Linux\_for\_Tegra comes from the driver package (Jetson\_Linux\_R35.3.1\_aarch64.tbz2) downloaded from the office website. The new libgstnvarguscamerasrc.so that I built however has a different checksum and it’s much bigger in size. I have also compared the gst-nvarguscamerasrc source code (r35.3.1) that I cloned with the source code in gst-nvarguscamera\_src.tbz2 from the Driver Package source (public\_sources.tbz2 for 35.3.1) downloaded from the website. They are identical. Another thing I have tried was building libgstnvarguscamerasrc.so for R35.1 from the source cloned from [https://nv-tegra.nvidia.com/r/tegra/gst-src/gst-nvarguscamera.git](https://nv-tegra.nvidia.com/r/tegra/gst-src/gst-nvarguscamera.git) and placing it onto a Jetson with r35.1. The gst capture command worked fine. So is there a bug in the R35.3.1 gst-nvarguscamera source code? Thanks ---

Could you download the source from below instead of clone from the git to check.

I realized that the version of the dependencies very likely matter. I got it to work by building it on Jetson with R35.3.1. And I was building it on another Jetson with R35.1. Also the source code from git and from the downloaded tarball is the same. ---
