Question on gst-nvv4l2 source code

Hi there.

I downloaded the r32v6.1 L4T sources and extracted gst-nvv4l2 source code.
I compiled the source code on NX.
But I found that generated file is larger than expected (compared with the one under /usr/lib/aarch64-linux-gnu/gstreamer-1.0/).

So where can I download the source code that matches the libs installed on NX?
If not possible, is there any side effect if I only replace


It should work if you have downloaded correct version. Please make sure both system and source code are r32.6.1. Please backup original before replacement.

And clean gstreamer cache for each replacement:

$ rm .cache/gstreamer-1.0/registry.aarch64.bin

Both system and source code are r32.6.1.
It seems my generated lib has more symbols than official one.
I didn’t change anything on the Makefile.
So is it because Nvidia applied different compilation options like -fvisibility=hidden?
