Here is the bugbase ticked: Bug#4130641 - [Android] Camera miniature display at top-left corner when StageVideo video playback
Camera miniature (about 10*10 pixels) display at top-left corner over video when StageVideo video playback. Note that I use simple video object to connect camera and even not add it to display list.
It has been tested with AIR 20, AIR 22.214.171.124 on Android 4.4.4 and Android 5.1.1. That works fine (fixed earlier) with AIR 126.96.36.199 beta.
