Problems with runtime CAMERA permission in video calls

I am working on video support via pjsip/pjsua2 for android.

My problem is with runtime camera permisson. No matter if I grant the
permission, video always fails on

Method)
at org.pjsip.pjsua2.VidDevManager.setCaptureOrient(VidDevManager.java:91)
at com.foo.bar.sip.client.core.SipCallManager$callListener$1.onCallMediaActivated(SipCallManager.kt:534)

at org.pjsip.pjsua2.pjsua2JNI.SwigDirector_Call_onCallMediaState(pjsua2JNI.java:2539)

However, next app launch everything works (after the crash)

Also, if I try catch it and restart the library it works

(since permission is already now granted)

My hypothesis is that the library predates runtime permissions and caches
something on startup, to which it wont have access to since permission is
not granted yet at library startup, And then even if granted, it uses
cached (invalid) values.

Anyone any idea about this? Has anyone got video working on targetSdk 23+?

TLDR; I initialize endpoint / library at app startup. I ask for permission
after clicking on Make call button. Only after granting the permission I
actually make the call via pjsip.

Starting endpoint only after granting permission is problematic since I
need the account registration status from the library to show / hide the
makeCall button.
But solution could be to to restart the pjsip after granting the permission
after clicking makeCall button.

However while incoming call, it is very problematic, since restarting the
pjsip stack would decline to call essentially.

Thanks
