I just can see L4T Multimedia API Reference version 32.3.1.

Is the version 32.3.1 of L4T Multimedia API on the way?
can I use the version 32.2.3 of L4T Multimedia API with L4T Sources(verson:32.3.1) together?

Please install it through SDKManager. After installation, you will see it in

No. The release versions have to be matched.
