I am currently trying to develop an Android video conference application on a Android TV set-top box. As all of us know, Android TV box does not have a camera and therefore I tried to use a USB web camera but the OS does not recognize the USB camera and is unable to retrieve video feed from it.
Is there anyway to make sure my Android application is able to receive video feed from the USB camera?
Thank you and sorry if I wrote this question inappropriately, it's my first time using Stackoverflow.
You have two choices:
1) Find a Android TV device which supports external camera(s). From the Android Compatibility Definition Document
Section 7.5.3. External Camera
Device implementations MAY include support for an external camera that is not necessarily
always connected. If a device includes support for an external camera, it:
* MUST declare the platform feature flag
android.hardware.camera.external and android.hardware camera.any .
* MAY support multiple cameras.
* MUST support USB Video Class (UVC 1.0 or higher) if the
external camera connects through the USB port.
* SHOULD support video compressions such as MJPEG to enable transfer
of high-quality unencoded streams (i.e. raw or independently compressed picture streams).
* MAY support camera-based video encoding. If supported, a simultaneous
unencoded / MJPEG stream (QVGA or greater resolution) MUST be
accessible to the device implementation.
OR
2) Create your own Custom ROM which would require having the code and drivers to satisfy the above requirement. This is non-trivial and involves creating/integrating/testing your own driver which is too broad for StackOverflow question.
