Well, it's not easy. A modified kernel is required to detect and interact with an HDMI device. To get the HDMI input from the device itself, you will need to write the NDK code. Then, after changing the input data to the appropriate format, which is compatible , for example, encoding it on H264, you can submit it to VideoView.
