RTSP Stream into OpenCV

Question

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 (ie selecting a template to match or something 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 All the documentation for how to pull an rtsp stream is either outdated, really confusing, or altogether non-existent.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?

Answer 1

There is an open source project that does precisely this combination.

1. Android generating the content from front or rear camera
2. RTSP protocol for streaming
3. h264
