h264_v4l2_rtspserver
====================

It is an RTSP server feed from an Video4Linux device that support H264 format.

It is based on :
- libv4l-dev to capture video frames
- liblivemedia-dev (http://www.live555.com) to implement RTSP server

The RTSP server support :
- RTP/UDP unicast
- RTP/UDP multicast
- RTP/TCP
- RTP/RTSP/HTTP

Dependencies
------------
 - liblivemedia-dev > live.2012.01.07 (need StreamReplicator)
 - libv4l-dev
 - liblog4cpp5-dev
 
Build
------- 
	git submodule init
	git submodule update
	cmake .
	make

If it fails you will need to install libv4l-dev liblivemedia-dev liblog4cpp5-dev.  
If it still not work you will need to read Makefile.  

Install
--------- 
	cpack .
	dpkg -i h264_v4l2_rtspserver*.deb

Raspberry Pi
------------ 
This RTSP server works on Raspberry Pi using :
- the unofficial V4L2 driver for the Raspberry Pi Camera Module http://www.linux-projects.org/modules/sections/index.php?op=viewarticle&artid=14
	sudo uv4l --driver raspicam --auto-video_nr --encoding h264
- the official V4L2 driver bcm2835-v4l2
	sudo modprobe -v bcm2835-v4l2
