[Linphone-developers] Liblinphone Android video call IO error

[Hieu Tang]

Hi,

I have been implementing Linphone in my Android app. The library is so great. I have followed closely with the Linphone-android source code.

I run into this error a few weeks ago and failed to find the cause ever since. When I tried to initiate video from one phone to another, receiving end would get this error message

When I use my app to call the official Linphone app from Play Store, same issue, Linphone app displays a popup “Unknown error – I/O error”.

It doesn’t happen for voice call. Where should I look into to find the cause?

Thanks in advance,
