[Q] < external USB UVC camera to tablet > - Android Q&A, Help & Troubleshooting

Hi,
I am looking for a solution to support external USB cameras on commercially available Android tablets (tablets that already contain internal camera).
The objective is to use a standard external USB UVC webcam to provide video to existing standard Android video conferencing apps (Skype, Ustream, LiveStream or other).
To do this, we need that it will support streaming video from a USB UVC camera using standard, unmodified versions of Android applications for voice and video. The external UVC camera device will be instead the front or back camera.
Do you have any idea?
Thanks.

HDMI vs. Internal Display in Android 5.0+

Hello all,
I was wondering if there is a workaround or an app to trick Android that you are on an internal display rather than connected to HDMI Port, similar with the "fake WI-FI" apps.
As a reason, I own a 5.1.1 Android Player, connected to a TV via HDMI, and when I try to use a paid movie streaming app, it is requesting to disconnect the external display. Similarly when I connect my Note 3 to a TV with MHL cable, same app is requesting to disconnect the external display. So it is working ONLY on internal displays, whether phone, tablet or SMART TV, which is a rude limitation for the payer, probably for copyright worries of the owner.
I would be very grateful if someone could point me a solution. The Android player manufacturer is stating that since Android 5.0 there is a signal regarding HDMI connection in Android system which triggers the app to block its usage, and I can confirm that on Android 4.4.4 there were no problems running the app on an external display (tested on another player running on 4.4.4).
Many thanks, in anticipate!
Enjoy!
