Video calls don't connect

[takiainen]

Riot might say "connecting" but displays just black screen or just constant "calling" despite receiver accepting the incoming call". It doesn't matter if I'm the caller or if I try to receive a video call.

Latest Riot on android 7.1.2 (no GAPPS).

For the call to get through with F-Droid version, I need to clear cache (even without killing the apps, only through the settings within the app) just before calling.
It seems that the issue raised at #1744 is correct, or at least the solution works for me.

@takiainen I have the same problem. My phone is a xiaomi redmi pro with double camera
