IP camera: open source software for recording H.264 [closed]

Question

I have an IP camera (Axis M1054) and I would like to record video stream. I would probably start with continuous recording, but then I would like to switch to clips triggered by motion detection (with pre-rec of couple seconds before the trigger occured), recording being encoded in MPEG4 (H.264), not in MJPEG.

Is there a free open source Linux software that can do it? I did not find anything by searching the Internet. Can you recommend something that works and you successfully use? Or am I stuck with commercial software?

I have no problem replacing the camera if different model would work better with Linux.

Answer 1

What about giving a try to open source openh264 backed by Cisco? It supports Long Term Reference (LTR) frames which might help you with motion detection.
