h264_v4l2_rtspserver
====================
2013-11-09 23:34:56 +00:00
2014-09-13 15:33:45 +00:00
It is an RTSP server feed from an Video4Linux device that support H264 format.
2013-11-09 23:34:56 +00:00
2014-09-13 15:33:45 +00:00
It is based on :
2013-11-10 14:41:05 +00:00
- libv4l-dev to capture video frames
- liblivemedia-dev (http://www.live555.com) to implement RTSP server
2013-11-09 23:34:56 +00:00
The RTSP server support :
- RTP/UDP unicast
- RTP/UDP multicast
- RTP/TCP
- RTP/RTSP/HTTP

cmake .
make
2014-11-22 14:35:59 +00:00
If it fails you will need to install libv4l-dev liblivemedia-dev liblog4cpp5-dev.
2014-08-15 22:33:02 +00:00
If it still not work you will need to read Makefile.

Raspberry Pi
------------
2014-08-18 21:35:23 +00:00
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
2015-01-22 21:37:35 +00:00

sudo uv4l --driver raspicam --auto-video_nr --encoding h264
2014-08-18 21:35:23 +00:00
- the official V4L2 driver bcm2835-v4l2
2015-01-22 21:37:35 +00:00
2015-01-22 21:30:27 +00:00
