For a school project my partner and I are trying to push video from an android tablet (Nexus 7) to a server (as an ip webcam), pull from the server into OpenCV 2.4.6, process that, send it back to a server, and have the tablet display the feed in real or near-real time.

We arent using opencv for android because the goal is for a remote user to decide how to process the video (i.e. selecting a template to match from the stream).

Our question is this: we have managed to get the android webcam stream onto a server as an h264 rtsp stream. All the documentation for how to pull an rtsp stream is either outdated, really confusing, or altogether non-existent. We tried using a VideoCapture object and then tried using cvCreateFileCapture but neither seem to be working. How do we do this?

This is a very general question, but in my professor's research lab he is wanting a cheaper, powerful tablet to run OpenCV on. However, we do not want to buy even a $200 tablet if we can't use OpenCV on it. So my question is probably a stupid one, but I can't find a definitive answer anywhere.

Does the Google Nexus 7 (2013) work with OpenCV? Has anyone used it? Are there better, cheaper options? It needs a rear facing camera and Wifi connectivity.

Thanks!
