Android app that users gStreamer to stream live video from android device

I need a developer to develop an android app that will utilize the GStreamer libraries to encode video from 2 camera sources simultaneously. Composite the video into picture in picture, while also using gpixbufoverlay and cairo to overlay graphics and data in real time. Will utilize RTMPSink and SRTsink as outputs.

All configuration will be sourced from a webAPI. The app will need to call the API on a regular basis to check for configuration updates.

User interface will simply be stop/start and preview (preview can be a T off of the H.264 pipeline to a local video sink).

Example working pipelines with gst-launch will be provided, but the app must hook glib/gst to do dynamic updating of elements in realtime so that changes can be made on the fly (and as new data comes in).
