Cannot stream over 4G

Version 1.2.12
Nice app !
Stream behind a router/wifi to a RTMP server is okay.
But on 4G, app throw connection error.
I tried to disable network connection : do not work.
Using another phone as a hotspot (with 4G) do work !
Really strange behavior !

Il manque une seul paramètre

Version 1.0.58
Ajouter adaptation du brightness svp


Version 1.0.45
J’aime beaucoup et pas de bug

Excellente appli !

Version 1.0.34
Fait exactement ce qu’on lui demande. 👍 Les paramètres sont simples d’accès et variés. Nice work. Est-ce possible d’intégrer des vu-mètres audio ?

Une application efficace

Version 1.0.32
Pour être un peu plus professionnel il faudrait un VU mètre pour contrôler le niveau audio. Et quelques contrôles de base de la caméra focus couverture.
