Re: [Linphone-users] Black screen when using video call

[Guillaume Beraudo]

Hi,

You should try to lower video size to qcif, in both directions.
This is done in linphonerc. In part by manipulating bandwidth limits.

Could you send logs of a call session?


Regarding srtp, I guess you disabled it.
If you are not building with belle-sip, you can ignore error message.
Conversely, you should compile from our git.


Could you please send the errors you had with -Werror?



Cheers,
Guillaume
