Hello, i am trying to start a rtspserver via gstreamer on android device. I am getting some error messages and i think i have some misconfiguration in android stuio because i get several file not found Errors

following you can find the error messages

In short they say that

- android cannot find libgstreamer\_android.so
- gst\_amc\_codec\_info\_to\_caps Unable to map AAC profile
- Didn’t find class “org/freedesktop/gstreamer/androidmedia/GstAhsCallback”
- GStreamer initialization complete

howerver i can see the files inside my project directory and they also seme to be at the right place. Since i also get the GStreamer initialization complete message i dont know if my c-code or my configuration is is wrong.

I appreciate any advice that you can give me to resolve that errors.
