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

License

Domain public

Dependencies

• liblivemedia-dev > live.2012.01.07 (need StreamReplicator)
• libv4l-dev
• liblog4cpp5-dev

Build

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

Usage

./h264_v4l2_rtspserver [-v[v]][-m] [-P RTSP port][-P RTSP/HTTP port][-Q queueSize] [-M mulcast group] [-r] [-s] [-W width] [-H height] [-F fps] [-O file] [device]
	 -v       : verbose
	 -vv      : very verbose
	 -Q length: Number of frame queue  (default 10)
	 -O output: Copy captured frame to a file or a V4L2 device
	 RTSP options :
	 -I addr  : RTSP interface (default autodetect)
	 -P port  : RTSP port (default 8554)
	 -T port  : RTSP over HTTP port (default 0)
	 -u url   : unicast url (default unicast)
	 -m url   : multicast url (default multicast)
	 -M addr  : multicast group  (default is a random address)
	 -c       : don't repeat config (default repeat config before IDR frame)
	 -t secs  : RTCP expiration timeout (default 65)
	 V4L2 options :
	 -r       : V4L2 capture using read interface (default use memory mapped buffers)
	 -s       : V4L2 capture using live555 mainloop (default use a separated reading thread)
	 -F fps   : V4L2 capture framerate (default 25)
