|
|
====================
|
|
|
|
This is an streamer feed from :

|
|
|
|
The RTSP server support :
|
|
- RTP/UDP unicast
|
|
- RTP/UDP multicast
|

|
|
|
|
Authentification is enable when almost one user is defined. You can configure credentials :
|
|
* using plain text password:
|
|
|
|
-U foo:bar -U admin:admin
|
|
* using md5 password:
|
|
|
|
-R myrealm -U foo:$(echo -n foo:myrealm:bar | md5sum | cut -d- -f1) -U admin:$(echo -n admin:myrealm:admin | md5sum | cut -d- -f1)
|
|
|
|
It is possible to compose the RTSP session is different ways :
|
|
* v4l2rtspserver /dev/video0 : one RTSP session with RTP video capturing V4L2 device /dev/video0
|
|
* v4l2rtspserver ,default : one RTSP session with RTP audio capturing ALSA device default
|
|
* v4l2rtspserver /dev/video0,default : one RTSP session with RTP audio and RTP video
|
|
* v4l2rtspserver /dev/video0 ,default : two RTSP sessions first one with RTP video and second one with RTP audio
|
|
* v4l2rtspserver /dev/video0 /dev/video1 : two RTSP sessions with an RTP video
|
|
* v4l2rtspserver /dev/video0,/dev/video0 : one RTSP session with RTP audio and RTP video (ALSA device associatd with the V4L2 device)

|
Build
|
|
-------
|
|
- Before build (optional)
|
|
The build try to install live555 package using apt-get, however in order to install live555 disabling check of port reuse, you can proceed like this:
|
|
|
|
wget http://www.live555.com/liveMedia/public/live555-latest.tar.gz -O - | tar xvzf -
|
|
cd live
|
|
./genMakefiles linux
|
|
sudo make CPPFLAGS=-DALLOW_RTSP_SERVER_PORT_REUSE=1 install
|
|
|
|
- Build
|
|
|
|
cmake . && make
|
|
|
|
If it fails you will need to install liblivemedia-dev liblog4cpp5-dev.
|
|
If it still not work you will need to read Makefile.
|
|
|
|
- Install (optional)
|
|
|
|
sudo make install
|
|
|
|
- Packaging (optional)
|
|
|
|
cpack .
|
|
|
|
Using Raspberry Pi Camera
|
|
-------------------------
|
|
This RTSP server works with Raspberry Pi camera using :
|
|
- the unofficial V4L2 driver for the Raspberry Pi Camera Module http://www.linux-projects.org/uv4l/
|
|
|
|
sudo uv4l --driver raspicam --auto-video_nr --encoding h264
|
|
- the official V4L2 driver bcm2835-v4l2
|
|
|
|
sudo modprobe -v bcm2835-v4l2
|
|
|
|
Using v4l2loopback
|
|
-----------------------
|
|
For camera providing uncompress format [v4l2tools](https://github.com/mpromonet/v4l2tools) can compress the video to an intermediate virtual V4L2 device [v4l2loopback](https://github.com/umlaeute/v4l2loopback):
|
|
|
|
/dev/video0 (camera device)-> v4l2compress_h264 -> /dev/video10 (v4l2loopback device) -> v4l2rtspserver
|
|
|
|
This workflow could be set using :
|
|
|
|
modprobe v4l2loopback video_nr=10
|
|
v4l2compress_h264 /dev/video0 /dev/video10 &
|
|
v4l2rtspserver /dev/video10 &
|
|
|
|
|
|
Playing HTTP streams
|
|
-----------------------
|
|
When v4l2rtspserver is started with '-S' arguments it also give access to streams through HTTP.
|
|
These streams could be played :
|
|
|
|
* for MPEG-DASH with :
|
|
MP4Client http://..../unicast.mpd
|
|
|
|
* for HLS with :
|
|
vlc http://..../unicast.m3u8
|
|
gstreamer-launch-1.0 playbin uri=http://.../unicast.m3u8
|
|
|
|
It is now possible to play HLS url directly from browser :
|
|
|
|
* using Firefox installing [Native HLS addons](https://addons.mozilla.org/en-US/firefox/addon/native_hls_playback)
|
|
* using Chrome installing [Native HLS playback](https://chrome.google.com/webstore/detail/native-hls-playback/emnphkkblegpebimobpbekeedfgemhof)
|
|
|
|
There is also a small HTML page that use hls.js and dash.js, but dash still not work because player doesnot support MP2T format.
