Describe the issue

My issue is when I start the app, i have this error:
ERR: libcamera is 64-bit, you need the 64-bit server version

I found what is causing, the "findLibrary" function checks the url with ldconfig is that contains the "arm-linux-gnueabihf" part.

mediamtx/internal/rpicamera/rpicamera.go

Line 89 in 21756a4

func findLibrary(name string) (string, error) {

With the v0.22.0 my yocto environment works(without the check). Maybe we can check that somehow else is this an 32bit or 64bit OS?

my ldconfig -p is contains this
libcamera.so.0.0.4 (libc6) => /usr/lib/libcamera.so.0.0.4
libcamera-base.so.0.0.4 (libc6) => /usr/lib/libcamera-base.so.0.0.4

Describe how to replicate the issue

Did you attach the server logs?

no

Did you attach a network dump?

no

Hello, due to #1644, the 32/64 bit check has to be performed on the library, not elsewhere. We can certainly find a better way to do it than checking the path name, for instance by analyzing the ELF header of the library, that may contain the 32/64 bit information.

I've moved the 64 bit check from the path to the ELF header of the library, please test this nightly release and confirm that the fix works:

I can confirm that is working in this way! Thanks!
