Gstomx1_src version problem

Hi folk.
Recently due to work reasons, I need to manually compile the library.

my device is TX2, Jetpack version is

cat /etc/nv_tegra_release
# R32 (release), REVISION: 4.4, GCID: 23942405, BOARD: t186ref, EABI: aarch64, DATE: Fri Oct 16 19:37:08 UTC 2020

I have checked the version of after refreshing jetpack 4.4,, it shows the version is 1.2.3 .

then, I download source code from download center (, and compile gstomx1_src to get, but I found the version is

Does anyone know why? where should I download the correct source code?

The source code is correct. Not sure why the versions do not match, but the code is directly packetized from our code base. Since we have deprecated omx plugins, suggest you try v4l2 plugins. It is also open source and you should see gst-v4l2 package.

I will try to compile v412 plugin and test it, thanks for your replay
