Nvcompositor crashes with more than one camera source

thanks for your reply,

I applied the patch meningitis here,

And it didn’t fix the issue.

I believe I would need this fix you mentioned here as well(“add a check if the attribute pointer exists before accessing it, it’ll go through that loop again later on anyway and set things up correctly”), so I wanted to know how did you manage to add this fix and build your own nvcompositor library. I tried to download the source code and it only include the header files and make file, so how could you get the c files to apply the fix?
